(libavformat + * always returns refcounted AVPackets, and av_frame_get_buffer() allocates + * refcounted AVFrames.) + * - Receive output in a loop. Periodically call one of the avcodec_receive_*() + * functions and process their output: + * - For decoding, call avcodec_receive_frame(). On success, it will return + * an AVFrame containing uncompressed audio or video data. + * - For encoding, call avcodec_receive_packet(). On success, it will return + * an AVPacket with a compressed frame. + * Repeat this call until it returns AVERROR(EAGAIN) or an error. The + * AVERROR(EAGAIN) return value means that new input data is required to + * return new output. In this case, continue with sending input. For each + * input frame/packet, the codec will typically return 1 output frame/packet, + * but it can also be 0 or more than 1. + * + * At the beginning of decoding or encoding, the codec might accept multiple + * input frames/packets without returning a frame, until its internal buffers + * are filled. This situation is handled transparently if you follow the steps + * outlined above. + * + * In theory, sending input can result in EAGAIN - this should happen only if + * not all output was received. You can use this to structure alternative decode + * or encode loops other than the one suggested above. For example, you could + * try sending new input on each iteration, and try to receive output if that + * returns EAGAIN. + * + * End of stream situations. These require "flushing" (aka draining) the codec, + * as the codec might buffer multiple frames or packets internally for + * performance or out of necessity (consider B-frames). + * This is handled as follows: + * - Instead of valid input, send NULL to the avcodec_send_packet() (decoding) + * or avcodec_send_frame() (encoding) functions. This will enter draining + * mode. + * - Call avcodec_receive_frame() (decoding) or avcodec_receive_packet() + * (encoding) in a loop until AVERROR_EOF is returned. The functions will + * not return AVERROR(EAGAIN), unless you forgot to enter draining mode. + * - Before decoding can be resumed again, the codec has to be reset with + * avcodec_flush_buffers(). + * + * Using the API as outlined above is highly recommended. But it is also + * possible to call functions outside of this rigid schema. For example, you can + * call avcodec_send_packet() repeatedly without calling + * avcodec_receive_frame(). In this case, avcodec_send_packet() will succeed + * until the codec's internal buffer has been filled up (which is typically of + * size 1 per output frame, after initial input), and then reject input with + * AVERROR(EAGAIN). Once it starts rejecting input, you have no choice but to + * read at least some output. + * + * Not all codecs will follow a rigid and predictable dataflow; the only + * guarantee is that an AVERROR(EAGAIN) return value on a send/receive call on + * one end implies that a receive/send call on the other end will succeed, or + * at least will not fail with AVERROR(EAGAIN). In general, no codec will + * permit unlimited buffering of input or output. + * + * This API replaces the following legacy functions: + * - avcodec_decode_video2() and avcodec_decode_audio4(): + * Use avcodec_send_packet() to feed input to the decoder, then use + * avcodec_receive_frame() to receive decoded frames after each packet. + * Unlike with the old video decoding API, multiple frames might result from + * a packet. For audio, splitting the input packet into frames by partially + * decoding packets becomes transparent to the API user. You never need to + * feed an AVPacket to the API twice (unless it is rejected with AVERROR(EAGAIN) - then + * no data was read from the packet). + * Additionally, sending a flush/draining packet is required only once. + * - avcodec_encode_video2()/avcodec_encode_audio2(): + * Use avcodec_send_frame() to feed input to the encoder, then use + * avcodec_receive_packet() to receive encoded packets. + * Providing user-allocated buffers for avcodec_receive_packet() is not + * possible. + * - The new API does not handle subtitles yet. + * + * Mixing new and old function calls on the same AVCodecContext is not allowed, + * and will result in undefined behavior. + * + * Some codecs might require using the new API; using the old API will return + * an error when calling it. All codecs support the new API. + * + * A codec is not allowed to return AVERROR(EAGAIN) for both sending and receiving. This + * would be an invalid state, which could put the codec user into an endless + * loop. The API has no concept of time either: it cannot happen that trying to + * do avcodec_send_packet() results in AVERROR(EAGAIN), but a repeated call 1 second + * later accepts the packet (with no other receive/flush API calls involved). + * The API is a strict state machine, and the passage of time is not supposed + * to influence it. Some timing-dependent behavior might still be deemed + * acceptable in certain cases. But it must never result in both send/receive + * returning EAGAIN at the same time at any point. It must also absolutely be + * avoided that the current state is "unstable" and can "flip-flop" between + * the send/receive APIs allowing progress. For example, it's not allowed that + * the codec randomly decides that it actually wants to consume a packet now + * instead of returning a frame, after it just returned AVERROR(EAGAIN) on an + * avcodec_send_packet() call. + * @} + */ + +/** + * @defgroup lavc_core Core functions/structures. + * @ingroup libavc + * + * Basic definitions, functions for querying libavcodec capabilities, + *

Its main two purposes are demuxing - i.e. splitting a media file + * into component streams, and the reverse process of muxing - writing supplied + * data in a specified container format. It also has an @ref lavf_io + * "I/O module" which supports a number of protocols for accessing the data (e.g. + * file, tcp, http and others). Before using lavf, you need to call + * av_register_all() to register all compiled muxers, demuxers and protocols. + * Unless you are absolutely sure you won't use libavformat's network + * capabilities, you should also call avformat_network_init(). + * + * A supported input format is described by an AVInputFormat struct, conversely + * an output format is described by AVOutputFormat. You can iterate over all + * registered input/output formats using the av_iformat_next() / + * av_oformat_next() functions. The protocols layer is not part of the public + * API, so you can only get the names of supported protocols with the + * avio_enum_protocols() function. + * + * Main lavf structure used for both muxing and demuxing is AVFormatContext, + * which exports all information about the file being read or written. As with + * most Libavformat structures, its size is not part of public ABI, so it cannot be + * allocated on stack or directly with av_malloc(). To create an + * AVFormatContext, use avformat_alloc_context() (some functions, like + * avformat_open_input() might do that for you). + * + * Most importantly an AVFormatContext contains: + * @li the @ref AVFormatContext.iformat "input" or @ref AVFormatContext.oformat + * "output" format. It is either autodetected or set by user for input; + * always set by user for output. + * @li an @ref AVFormatContext.streams "array" of AVStreams, which describe all + * elementary streams stored in the file. AVStreams are typically referred to + * using their index in this array. + * @li an @ref AVFormatContext.pb "I/O context". It is either opened by lavf or + * set by user for input, always set by user for output (unless you are dealing + * with an AVFMT_NOFILE format). + * + * @section lavf_options Passing options to (de)muxers + * It is possible to configure lavf muxers and demuxers using the @ref avoptions + * mechanism. Generic (format-independent) libavformat options are provided by + * AVFormatContext, they can be examined from a user program by calling + * av_opt_next() / av_opt_find() on an allocated AVFormatContext (or its AVClass + * from avformat_get_class()). Private (format-specific) options are provided by + * AVFormatContext.priv_data if and only if AVInputFormat.priv_class / + * AVOutputFormat.priv_class of the corresponding format struct is non-NULL. + * Further options may be provided by the @ref AVFormatContext.pb "I/O context", + * if its AVClass is non-NULL, and the protocols layer. See the discussion on + * nesting in @ref avoptions documentation to learn how to access those. + * + * @section urls + * URL strings in libavformat are made of a scheme/protocol, a ':', and a + * scheme specific string. URLs without a scheme and ':' used for local files + * are supported but deprecated. "file:" should be used for local files. + * + * It is important that the scheme string is not taken from untrusted + * sources without checks. + * + * Note that some schemes/protocols are quite powerful, allowing access to + * both local and remote files, parts of them, concatenations of them, local + * audio and video devices and so on. + * + * @{ + * + * @defgroup lavf_decoding Demuxing + * @{ + * Demuxers read a media file and split it into chunks of data (@em packets). A + * @ref AVPacket "packet" contains one or more encoded frames which belongs to a + * single elementary stream. In the lavf API this process is represented by the + * avformat_open_input() function for opening a file, av_read_frame() for + * reading a single packet and finally avformat_close_input(), which does the + * cleanup. + * + * @section lavf_decoding_open Opening a media file + * The minimum information required to open a file is its URL, which + * is passed to avformat_open_input(), as in the following code: + * @code + * const char *url = "file:in.mp3"; + * AVFormatContext *s = NULL; + * int ret = avformat_open_input(&s, url, NULL, NULL); + * if (ret < 0) + * abort(); + * @endcode + * The above code attempts to allocate an AVFormatContext, open the + * specified file (autodetecting the format) and read the header, exporting the + * information stored there into s. Some formats do not have a header or do not + * store enough information there, so it is recommended that you call the + * avformat_find_stream_info() function which tries to read and decode a few + * frames to find missing information. + * + * In some cases you might want to preallocate an AVFormatContext yourself with + * avformat_alloc_context() and do some tweaking on it before passing it to + * avformat_open_input(). One such case is when you want to use custom functions + * for reading input data instead of lavf internal I/O layer. + * To do that, create your own AVIOContext with avio_alloc_context(), passing + * your reading callbacks to it. Then set the @em pb field of your + * AVFormatContext to newly created AVIOContext. + * + * Since the format of the opened file is in general not known until after + * avformat_open_input() has returned, it is not possible to set demuxer private + * options on a preallocated context. Instead, the options should be passed to + * avformat_open_input() wrapped in an AVDictionary: + * @code + * AVDictionary *options = NULL; + * av_dict_set(&options, "video_size", "640x480", 0); + * av_dict_set(&options, "pixel_format", "rgb24", 0); + * + * if (avformat_open_input(&s, url, NULL, &options) < 0) + * abort(); + * av_dict_free(&options); + * @endcode + * This code passes the private options 'video_size' and 'pixel_format' to the + * demuxer. They would be necessary for e.g. the rawvideo demuxer, since it + * cannot know how to interpret raw video data otherwise. If the format turns + * out to be something different than raw video, those options will not be + * recognized by the demuxer and therefore will not be applied. Such unrecognized + * options are then returned in the options dictionary (recognized options are + * consumed). The calling program can handle such unrecognized options as it + * wishes, e.g. + * @code + * AVDictionaryEntry *e; + * if (e = av_dict_get(options, "", NULL, AV_DICT_IGNORE_SUFFIX)) { + * fprintf(stderr, "Option %s not recognized by the demuxer.\n", e->key); + * abort(); + * } + * @endcode + * + * After you have finished reading the file, you must close it with + * avformat_close_input().

The caller then sets up + * the muxer by filling the various fields in this context: + * + * - The @ref AVFormatContext.oformat "oformat" field must be set to select the + * muxer that will be used. + * - Unless the format is of the AVFMT_NOFILE type, the @ref AVFormatContext.pb + * "pb" field must be set to an opened IO context, either returned from + * avio_open2() or a custom one. + * - Unless the format is of the AVFMT_NOSTREAMS type, at least one stream must + * be created with the avformat_new_stream() function. The caller should fill + * the @ref AVStream.codecpar "stream codec parameters" information, such as the + * codec @ref AVCodecParameters.codec_type "type", @ref AVCodecParameters.codec_id + * "id" and other parameters (e.g. width / height, the pixel or sample format, + * etc.) as known. The @ref AVStream.time_base "stream timebase" should + * be set to the timebase that the caller desires to use for this stream (note + * that the timebase actually used by the muxer can be different, as will be + * described later). + * - It is advised to manually initialize only the relevant fields in + * AVCodecParameters, rather than using @ref avcodec_parameters_copy() during + * remuxing: there is no guarantee that the codec context values remain valid + * for both input and output format contexts. + * - The caller may fill in additional information, such as @ref + * AVFormatContext.metadata "global" or @ref AVStream.metadata "per-stream" + * metadata, @ref AVFormatContext.chapters "chapters", @ref + * AVFormatContext.programs "programs", etc. as described in the + * AVFormatContext documentation. Whether such information will actually be + * stored in the output depends on what the container format and the muxer + * support. + * + * When the muxing context is fully set up, the caller must call + * avformat_write_header() to initialize the muxer internals and write the file + * header. Whether anything actually is written to the IO context at this step + * depends on the muxer, but this function must always be called. Any muxer + * private options must be passed in the options parameter to this function. + * + * The data is then sent to the muxer by repeatedly calling av_write_frame() or + * av_interleaved_write_frame() (consult those functions' documentation for + * discussion on the difference between them; only one of them may be used with + * a single muxing context, they should not be mixed). Do note that the timing + * information on the packets sent to the muxer must be in the corresponding + * AVStream's timebase. That timebase is set by the muxer (in the + * avformat_write_header() step) and may be different from the timebase + * requested by the caller. + * + * Once all the data has been written, the caller must call av_write_trailer() + * to flush any buffered packets and finalize the output file, then close the IO + * context (if any) and finally free the muxing context with + * avformat_free_context(). + * @} + * + * @defgroup lavf_io I/O Read/Write + * @{ + * @section lavf_io_dirlist Directory listing + * The directory listing API makes it possible to list files on remote servers. + * + * Some of possible use cases: + * - an "open file" dialog to choose files from a remote location, + * - a recursive media finder providing a player with an ability to play all + * files from a given directory. + * + * @subsection lavf_io_dirlist_open Opening a directory + * At first, a directory needs to be opened by calling avio_open_dir() + * supplied with a URL and, optionally, ::AVDictionary containing + * protocol-specific parameters.

Conversely it allows a client application to + * set metadata when muxing. + * + * Metadata is exported or set as pairs of key/value strings in the 'metadata' + * fields of the AVFormatContext, AVStream, AVChapter and AVProgram structs + * using the @ref lavu_dict "AVDictionary" API. Like all strings in FFmpeg, + * metadata is assumed to be UTF-8 encoded Unicode. Note that metadata + * exported by demuxers isn't checked to be valid UTF-8 in most cases. + * + * Important concepts to keep in mind: + * - Keys are unique; there can never be 2 tags with the same key. This is + * also meant semantically, i.e., a demuxer should not knowingly produce + * several keys that are literally different but semantically identical. + * E.g., key=Author5, key=Author6. In this example, all authors must be + * placed in the same tag. + * - Metadata is flat, not hierarchical; there are no subtags. If you + * want to store, e.g., the email address of the child of producer Alice + * and actor Bob, that could have key=alice_and_bobs_childs_email_address. + * - Several modifiers can be applied to the tag name. This is done by + * appending a dash character ('-') and the modifier name in the order + * they appear in the list below -- e.g. foo-eng-sort, not foo-sort-eng. + * - language -- a tag whose value is localized for a particular language + * is appended with the ISO 639-2/B 3-letter language code. + * For example: Author-ger=Michael, Author-eng=Mike + * The original/default language is in the unqualified "Author" tag. + * A demuxer should set a default if it sets any translated tag. + * - sorting -- a modified version of a tag that should be used for + * sorting will have '-sort' appended. E.g. artist="The Beatles", + * artist-sort="Beatles, The". + * - Some protocols and demuxers support metadata updates. After a successful + * call to av_read_packet(), AVFormatContext.event_flags or AVStream.event_flags + * will be updated to indicate if metadata changed. In order to detect metadata + * changes on a stream, you need to loop through all streams in the AVFormatContext + * and check their individual event_flags. + * + * - Demuxers attempt to export metadata in a generic format, however tags + * with no generic equivalents are left as they are stored in the container. + * Follows a list of generic tag names: + * + @verbatim + album -- name of the set this work belongs to + album_artist -- main creator of the set/album, if different from artist. + e.g. "Various Artists" for compilation albums. + artist -- main creator of the work + comment -- any additional description of the file. + composer -- who composed the work, if different from artist. + copyright -- name of copyright holder. + creation_time-- date when the file was created, preferably in ISO 8601. + date -- date when the work was created, preferably in ISO 8601. + disc -- number of a subset, e.g. disc in a multi-disc collection. + encoder -- name/settings of the software/hardware that produced the file. + encoded_by -- person/group who created the file. + filename -- original name of the file. + genre -- . + language -- main language in which the work is performed, preferably + in ISO 639-2 format. Multiple languages can be specified by + separating them with commas. + performer -- artist who performed the work, if different from artist. + E.g for "Also sprach Zarathustra", artist would be "Richard + Strauss" and performer "London Philharmonic Orchestra". + publisher -- name of the label/publisher. + service_name -- name of the service in broadcasting (channel name). + service_provider -- name of the service provider in broadcasting. + title -- name of the work. + track -- number of this work in the set, can be in form current/total. + variant_bitrate -- the total bitrate of the bitrate variant that the current stream is part of + @endverbatim + * + * Look in the examples section for an application example how to use the Metadata API. + * + * @} + */ + +/* packet functions */ + + +/** + * Allocate and read the payload of a packet and initialize its + * fields with default values. + * + * @param s associated IO context + * @param pkt packet + * @param size desired payload size + * @return >0 (read size) if OK, AVERROR_xxx otherwise + */ +int av_get_packet(AVIOContext *s, AVPacket *pkt, int size); + + +/** + * Read data and append it to the current content of the AVPacket. + * If pkt->size is 0 this is identical to av_get_packet. + * Note that this uses av_grow_packet and thus involves a realloc + * which is inefficient.

Therefore + * the first member of the struct should be a pointer to an AVClass describing it. + * The option field of the AVClass must be set to a NULL-terminated static array + * of AVOptions.

In such a case, it is possible to set up the + * parent struct to export a child's options. To do that, simply + * implement AVClass.child_next() and AVClass.child_class_next() in the + * parent struct's AVClass. + * Assuming that the test_struct from above now also contains a + * child_struct field: + * + * @code + * typedef struct child_struct { + * AVClass *class; + * int flags_opt; + * } child_struct; + * static const AVOption child_opts[] = { + * { "test_flags", "This is a test option of flags type.", + * offsetof(child_struct, flags_opt), AV_OPT_TYPE_FLAGS, { .i64 = 0 }, INT_MIN, INT_MAX }, + * { NULL }, + * }; + * static const AVClass child_class = { + * .class_name = "child class", + * .item_name = av_default_item_name, + * .option = child_opts, + * .version = LIBAVUTIL_VERSION_INT, + * }; + * + * void *child_next(void *obj, void *prev) + * { + * test_struct *t = obj; + * if (!prev && t->child_struct) + * return t->child_struct; + * return NULL + * } + * const AVClass child_class_next(const AVClass *prev) + * { + * return prev ? NULL : &child_class; + * } + * @endcode + * Putting child_next() and child_class_next() as defined above into + * test_class will now make child_struct's options accessible through + * test_struct (again, proper setup as described above needs to be done on + * child_struct right after it is created). + * + * From the above example it might not be clear why both child_next() + * and child_class_next() are needed. The distinction is that child_next() + * iterates over actually existing objects, while child_class_next() + * iterates over all possible child classes. E.g. if an AVCodecContext + * was initialized to use a codec which has private options, then its + * child_next() will return AVCodecContext.priv_data and finish + * iterating. OTOH child_class_next() on AVCodecContext.av_class will + * iterate over all available codecs with private options. + * + * @subsection avoptions_implement_named_constants Named constants + * It is possible to create named constants for options. Simply set the unit + * field of the option the constants should apply to a string and + * create the constants themselves as options of type AV_OPT_TYPE_CONST + * with their unit field set to the same string. + * Their default_val field should contain the value of the named + * constant. + * For example, to add some named constants for the test_flags option + * above, put the following into the child_opts array: + * @code + * { "test_flags", "This is a test option of flags type.", + * offsetof(child_struct, flags_opt), AV_OPT_TYPE_FLAGS, { .i64 = 0 }, INT_MIN, INT_MAX, "test_unit" }, + * { "flag1", "This is a flag with value 16", 0, AV_OPT_TYPE_CONST, { .i64 = 16 }, 0, 0, "test_unit" }, + * @endcode + * + * @section avoptions_use Using AVOptions + * This section deals with accessing options in an AVOptions-enabled struct. + * Such structs in FFmpeg are e.g. AVCodecContext in libavcodec or + * AVFormatContext in libavformat. + * + * @subsection avoptions_use_examine Examining AVOptions + * The basic functions for examining options are av_opt_next(), which iterates + * over all options defined for one object, and av_opt_find(), which searches + * for an option with the given name. + * + * The situation is more complicated with nesting. An AVOptions-enabled struct + * may have AVOptions-enabled children. Passing the AV_OPT_SEARCH_CHILDREN flag + * to av_opt_find() will make the function search children recursively. + * + * For enumerating there are basically two cases. The first is when you want to + * get all options that may potentially exist on the struct and its children + * (e.g. when constructing documentation). In that case you should call + * av_opt_child_class_next() recursively on the parent struct's AVClass. The + * second case is when you have an already initialized struct with all its + * children and you want to get all options that can be actually written or read + * from it. In that case you should call av_opt_child_next() recursively (and + * av_opt_next() on each result). + * + * @subsection avoptions_use_get_set Reading and writing AVOptions + * When setting options, you often have a string read directly from the + * user. In such a case, simply passing it to av_opt_set() is enough. For + * non-string type options, av_opt_set() will parse the string according to the + * option type. + * + * Similarly av_opt_get() will read any option type and convert it to a string + * which will be returned.

(libavformat + * always returns refcounted AVPackets, and av_frame_get_buffer() allocates + * refcounted AVFrames.) + * - Receive output in a loop. Periodically call one of the avcodec_receive_*() + * functions and process their output: + * - For decoding, call avcodec_receive_frame(). On success, it will return + * an AVFrame containing uncompressed audio or video data. + * - For encoding, call avcodec_receive_packet(). On success, it will return + * an AVPacket with a compressed frame. + * Repeat this call until it returns AVERROR(EAGAIN) or an error. The + * AVERROR(EAGAIN) return value means that new input data is required to + * return new output. In this case, continue with sending input. For each + * input frame/packet, the codec will typically return 1 output frame/packet, + * but it can also be 0 or more than 1. + * + * At the beginning of decoding or encoding, the codec might accept multiple + * input frames/packets without returning a frame, until its internal buffers + * are filled. This situation is handled transparently if you follow the steps + * outlined above. + * + * In theory, sending input can result in EAGAIN - this should happen only if + * not all output was received. You can use this to structure alternative decode + * or encode loops other than the one suggested above. For example, you could + * try sending new input on each iteration, and try to receive output if that + * returns EAGAIN. + * + * End of stream situations. These require "flushing" (aka draining) the codec, + * as the codec might buffer multiple frames or packets internally for + * performance or out of necessity (consider B-frames). + * This is handled as follows: + * - Instead of valid input, send NULL to the avcodec_send_packet() (decoding) + * or avcodec_send_frame() (encoding) functions. This will enter draining + * mode. + * - Call avcodec_receive_frame() (decoding) or avcodec_receive_packet() + * (encoding) in a loop until AVERROR_EOF is returned. The functions will + * not return AVERROR(EAGAIN), unless you forgot to enter draining mode. + * - Before decoding can be resumed again, the codec has to be reset with + * avcodec_flush_buffers(). + * + * Using the API as outlined above is highly recommended. But it is also + * possible to call functions outside of this rigid schema. For example, you can + * call avcodec_send_packet() repeatedly without calling + * avcodec_receive_frame(). In this case, avcodec_send_packet() will succeed + * until the codec's internal buffer has been filled up (which is typically of + * size 1 per output frame, after initial input), and then reject input with + * AVERROR(EAGAIN). Once it starts rejecting input, you have no choice but to + * read at least some output. + * + * Not all codecs will follow a rigid and predictable dataflow; the only + * guarantee is that an AVERROR(EAGAIN) return value on a send/receive call on + * one end implies that a receive/send call on the other end will succeed, or + * at least will not fail with AVERROR(EAGAIN). In general, no codec will + * permit unlimited buffering of input or output. + * + * This API replaces the following legacy functions: + * - avcodec_decode_video2() and avcodec_decode_audio4(): + * Use avcodec_send_packet() to feed input to the decoder, then use + * avcodec_receive_frame() to receive decoded frames after each packet. + * Unlike with the old video decoding API, multiple frames might result from + * a packet. For audio, splitting the input packet into frames by partially + * decoding packets becomes transparent to the API user. You never need to + * feed an AVPacket to the API twice (unless it is rejected with AVERROR(EAGAIN) - then + * no data was read from the packet). + * Additionally, sending a flush/draining packet is required only once. + * - avcodec_encode_video2()/avcodec_encode_audio2(): + * Use avcodec_send_frame() to feed input to the encoder, then use + * avcodec_receive_packet() to receive encoded packets. + * Providing user-allocated buffers for avcodec_receive_packet() is not + * possible. + * - The new API does not handle subtitles yet. + * + * Mixing new and old function calls on the same AVCodecContext is not allowed, + * and will result in undefined behavior. + * + * Some codecs might require using the new API; using the old API will return + * an error when calling it. All codecs support the new API. + * + * A codec is not allowed to return AVERROR(EAGAIN) for both sending and receiving. This + * would be an invalid state, which could put the codec user into an endless + * loop. The API has no concept of time either: it cannot happen that trying to + * do avcodec_send_packet() results in AVERROR(EAGAIN), but a repeated call 1 second + * later accepts the packet (with no other receive/flush API calls involved). + * The API is a strict state machine, and the passage of time is not supposed + * to influence it. Some timing-dependent behavior might still be deemed + * acceptable in certain cases. But it must never result in both send/receive + * returning EAGAIN at the same time at any point. It must also absolutely be + * avoided that the current state is "unstable" and can "flip-flop" between + * the send/receive APIs allowing progress. For example, it's not allowed that + * the codec randomly decides that it actually wants to consume a packet now + * instead of returning a frame, after it just returned AVERROR(EAGAIN) on an + * avcodec_send_packet() call. + * @} + */ + +/** + * @defgroup lavc_core Core functions/structures. + * @ingroup libavc + * + * Basic definitions, functions for querying libavcodec capabilities, + *

Its main two purposes are demuxing - i.e. splitting a media file + * into component streams, and the reverse process of muxing - writing supplied + * data in a specified container format. It also has an @ref lavf_io + * "I/O module" which supports a number of protocols for accessing the data (e.g. + * file, tcp, http and others). Before using lavf, you need to call + * av_register_all() to register all compiled muxers, demuxers and protocols. + * Unless you are absolutely sure you won't use libavformat's network + * capabilities, you should also call avformat_network_init(). + * + * A supported input format is described by an AVInputFormat struct, conversely + * an output format is described by AVOutputFormat. You can iterate over all + * registered input/output formats using the av_iformat_next() / + * av_oformat_next() functions. The protocols layer is not part of the public + * API, so you can only get the names of supported protocols with the + * avio_enum_protocols() function. + * + * Main lavf structure used for both muxing and demuxing is AVFormatContext, + * which exports all information about the file being read or written. As with + * most Libavformat structures, its size is not part of public ABI, so it cannot be + * allocated on stack or directly with av_malloc(). To create an + * AVFormatContext, use avformat_alloc_context() (some functions, like + * avformat_open_input() might do that for you). + * + * Most importantly an AVFormatContext contains: + * @li the @ref AVFormatContext.iformat "input" or @ref AVFormatContext.oformat + * "output" format. It is either autodetected or set by user for input; + * always set by user for output. + * @li an @ref AVFormatContext.streams "array" of AVStreams, which describe all + * elementary streams stored in the file. AVStreams are typically referred to + * using their index in this array. + * @li an @ref AVFormatContext.pb "I/O context". It is either opened by lavf or + * set by user for input, always set by user for output (unless you are dealing + * with an AVFMT_NOFILE format). + * + * @section lavf_options Passing options to (de)muxers + * It is possible to configure lavf muxers and demuxers using the @ref avoptions + * mechanism. Generic (format-independent) libavformat options are provided by + * AVFormatContext, they can be examined from a user program by calling + * av_opt_next() / av_opt_find() on an allocated AVFormatContext (or its AVClass + * from avformat_get_class()). Private (format-specific) options are provided by + * AVFormatContext.priv_data if and only if AVInputFormat.priv_class / + * AVOutputFormat.priv_class of the corresponding format struct is non-NULL. + * Further options may be provided by the @ref AVFormatContext.pb "I/O context", + * if its AVClass is non-NULL, and the protocols layer. See the discussion on + * nesting in @ref avoptions documentation to learn how to access those. + * + * @section urls + * URL strings in libavformat are made of a scheme/protocol, a ':', and a + * scheme specific string. URLs without a scheme and ':' used for local files + * are supported but deprecated. "file:" should be used for local files. + * + * It is important that the scheme string is not taken from untrusted + * sources without checks. + * + * Note that some schemes/protocols are quite powerful, allowing access to + * both local and remote files, parts of them, concatenations of them, local + * audio and video devices and so on. + * + * @{ + * + * @defgroup lavf_decoding Demuxing + * @{ + * Demuxers read a media file and split it into chunks of data (@em packets). A + * @ref AVPacket "packet" contains one or more encoded frames which belongs to a + * single elementary stream. In the lavf API this process is represented by the + * avformat_open_input() function for opening a file, av_read_frame() for + * reading a single packet and finally avformat_close_input(), which does the + * cleanup. + * + * @section lavf_decoding_open Opening a media file + * The minimum information required to open a file is its URL, which + * is passed to avformat_open_input(), as in the following code: + * @code + * const char *url = "file:in.mp3"; + * AVFormatContext *s = NULL; + * int ret = avformat_open_input(&s, url, NULL, NULL); + * if (ret < 0) + * abort(); + * @endcode + * The above code attempts to allocate an AVFormatContext, open the + * specified file (autodetecting the format) and read the header, exporting the + * information stored there into s. Some formats do not have a header or do not + * store enough information there, so it is recommended that you call the + * avformat_find_stream_info() function which tries to read and decode a few + * frames to find missing information. + * + * In some cases you might want to preallocate an AVFormatContext yourself with + * avformat_alloc_context() and do some tweaking on it before passing it to + * avformat_open_input(). One such case is when you want to use custom functions + * for reading input data instead of lavf internal I/O layer. + * To do that, create your own AVIOContext with avio_alloc_context(), passing + * your reading callbacks to it. Then set the @em pb field of your + * AVFormatContext to newly created AVIOContext. + * + * Since the format of the opened file is in general not known until after + * avformat_open_input() has returned, it is not possible to set demuxer private + * options on a preallocated context. Instead, the options should be passed to + * avformat_open_input() wrapped in an AVDictionary: + * @code + * AVDictionary *options = NULL; + * av_dict_set(&options, "video_size", "640x480", 0); + * av_dict_set(&options, "pixel_format", "rgb24", 0); + * + * if (avformat_open_input(&s, url, NULL, &options) < 0) + * abort(); + * av_dict_free(&options); + * @endcode + * This code passes the private options 'video_size' and 'pixel_format' to the + * demuxer. They would be necessary for e.g. the rawvideo demuxer, since it + * cannot know how to interpret raw video data otherwise. If the format turns + * out to be something different than raw video, those options will not be + * recognized by the demuxer and therefore will not be applied. Such unrecognized + * options are then returned in the options dictionary (recognized options are + * consumed). The calling program can handle such unrecognized options as it + * wishes, e.g. + * @code + * AVDictionaryEntry *e; + * if (e = av_dict_get(options, "", NULL, AV_DICT_IGNORE_SUFFIX)) { + * fprintf(stderr, "Option %s not recognized by the demuxer.\n", e->key); + * abort(); + * } + * @endcode + * + * After you have finished reading the file, you must close it with + * avformat_close_input(). It will free everything associated with the file. + * + * @section lavf_decoding_read Reading from an opened file + * Reading data from an opened AVFormatContext is done by repeatedly calling + * av_read_frame() on it. Each call, if successful, will return an AVPacket + * containing encoded data for one AVStream, identified by + * AVPacket.stream_index. This packet may be passed straight into the libavcodec + * decoding functions avcodec_send_packet() or avcodec_decode_subtitle2() if the + * caller wishes to decode the data. + * + * AVPacket.pts, AVPacket.dts and AVPacket.duration timing information will be + * set if known. They may also be unset (i.e. AV_NOPTS_VALUE for + * pts/dts, 0 for duration) if the stream does not provide them. The timing + * information will be in AVStream.time_base units, i.e. it has to be + * multiplied by the timebase to convert them to seconds. + * + * If AVPacket.buf is set on the returned packet, then the packet is + * allocated dynamically and the user may keep it indefinitely. + * Otherwise, if AVPacket.buf is NULL, the packet data is backed by a + * static storage somewhere inside the demuxer and the packet is only valid + * until the next av_read_frame() call or closing the file. If the caller + * requires a longer lifetime, av_dup_packet() will make an av_malloc()ed copy + * of it. + * In both cases, the packet must be freed with av_packet_unref() when it is no + * longer needed. + * + * @section lavf_decoding_seek Seeking + * @} + * + * @defgroup lavf_encoding Muxing + * @{ + * Muxers take encoded data in the form of @ref AVPacket "AVPackets" and write + * it into files or other output bytestreams in the specified container format. + * + * The main API functions for muxing are avformat_write_header() for writing the + * file header, av_write_frame() / av_interleaved_write_frame() for writing the + * packets and av_write_trailer() for finalizing the file. + * + * At the beginning of the muxing process, the caller must first call + * avformat_alloc_context() to create a muxing context. The caller then sets up + * the muxer by filling the various fields in this context: + * + * - The @ref AVFormatContext.oformat "oformat" field must be set to select the + * muxer that will be used. + * - Unless the format is of the AVFMT_NOFILE type, the @ref AVFormatContext.pb + * "pb" field must be set to an opened IO context, either returned from + * avio_open2() or a custom one. + * - Unless the format is of the AVFMT_NOSTREAMS type, at least one stream must + * be created with the avformat_new_stream() function. The caller should fill + * the @ref AVStream.codecpar "stream codec parameters" information, such as the + * codec @ref AVCodecParameters.codec_type "type", @ref AVCodecParameters.codec_id + * "id" and other parameters (e.g. width / height, the pixel or sample format, + * etc.) as known. The @ref AVStream.time_base "stream timebase" should + * be set to the timebase that the caller desires to use for this stream (note + * that the timebase actually used by the muxer can be different, as will be + * described later). + * - It is advised to manually initialize only the relevant fields in + * AVCodecParameters, rather than using @ref avcodec_parameters_copy() during + * remuxing: there is no guarantee that the codec context values remain valid + * for both input and output format contexts. + * - The caller may fill in additional information, such as @ref + * AVFormatContext.metadata "global" or @ref AVStream.metadata "per-stream" + * metadata, @ref AVFormatContext.chapters "chapters", @ref + * AVFormatContext.programs "programs", etc. as described in the + * AVFormatContext documentation. Whether such information will actually be + * stored in the output depends on what the container format and the muxer + * support. + * + * When the muxing context is fully set up, the caller must call + * avformat_write_header() to initialize the muxer internals and write the file + * header. Whether anything actually is written to the IO context at this step + * depends on the muxer, but this function must always be called. Any muxer + * private options must be passed in the options parameter to this function. + * + * The data is then sent to the muxer by repeatedly calling av_write_frame() or + * av_interleaved_write_frame() (consult those functions' documentation for + * discussion on the difference between them; only one of them may be used with + * a single muxing context, they should not be mixed). Do note that the timing + * information on the packets sent to the muxer must be in the corresponding + * AVStream's timebase. That timebase is set by the muxer (in the + * avformat_write_header() step) and may be different from the timebase + * requested by the caller. + * + * Once all the data has been written, the caller must call av_write_trailer() + * to flush any buffered packets and finalize the output file, then close the IO + * context (if any) and finally free the muxing context with + * avformat_free_context(). + * @} + * + * @defgroup lavf_io I/O Read/Write + * @{ + * @section lavf_io_dirlist Directory listing + * The directory listing API makes it possible to list files on remote servers. + * + * Some of possible use cases: + * - an "open file" dialog to choose files from a remote location, + * - a recursive media finder providing a player with an ability to play all + * files from a given directory. + * + * @subsection lavf_io_dirlist_open Opening a directory + * At first, a directory needs to be opened by calling avio_open_dir() + * supplied with a URL and, optionally, ::AVDictionary containing + * protocol-specific parameters.

Conversely it allows a client application to + * set metadata when muxing. + * + * Metadata is exported or set as pairs of key/value strings in the 'metadata' + * fields of the AVFormatContext, AVStream, AVChapter and AVProgram structs + * using the @ref lavu_dict "AVDictionary" API. Like all strings in FFmpeg, + * metadata is assumed to be UTF-8 encoded Unicode. Note that metadata + * exported by demuxers isn't checked to be valid UTF-8 in most cases. + * + * Important concepts to keep in mind: + * - Keys are unique; there can never be 2 tags with the same key. This is + * also meant semantically, i.e., a demuxer should not knowingly produce + * several keys that are literally different but semantically identical. + * E.g., key=Author5, key=Author6. In this example, all authors must be + * placed in the same tag. + * - Metadata is flat, not hierarchical; there are no subtags. If you + * want to store, e.g., the email address of the child of producer Alice + * and actor Bob, that could have key=alice_and_bobs_childs_email_address. + * - Several modifiers can be applied to the tag name. This is done by + * appending a dash character ('-') and the modifier name in the order + * they appear in the list below -- e.g. foo-eng-sort, not foo-sort-eng. + * - language -- a tag whose value is localized for a particular language + * is appended with the ISO 639-2/B 3-letter language code. + * For example: Author-ger=Michael, Author-eng=Mike + * The original/default language is in the unqualified "Author" tag. + * A demuxer should set a default if it sets any translated tag. + * - sorting -- a modified version of a tag that should be used for + * sorting will have '-sort' appended. E.g. artist="The Beatles", + * artist-sort="Beatles, The". + * - Some protocols and demuxers support metadata updates. After a successful + * call to av_read_packet(), AVFormatContext.event_flags or AVStream.event_flags + * will be updated to indicate if metadata changed. In order to detect metadata + * changes on a stream, you need to loop through all streams in the AVFormatContext + * and check their individual event_flags. + * + * - Demuxers attempt to export metadata in a generic format, however tags + * with no generic equivalents are left as they are stored in the container. + * Follows a list of generic tag names: + * + @verbatim + album -- name of the set this work belongs to + album_artist -- main creator of the set/album, if different from artist. + e.g. "Various Artists" for compilation albums. + artist -- main creator of the work + comment -- any additional description of the file. + composer -- who composed the work, if different from artist. + copyright -- name of copyright holder. + creation_time-- date when the file was created, preferably in ISO 8601. + date -- date when the work was created, preferably in ISO 8601. + disc -- number of a subset, e.g. disc in a multi-disc collection. + encoder -- name/settings of the software/hardware that produced the file. + encoded_by -- person/group who created the file. + filename -- original name of the file. + genre -- . + language -- main language in which the work is performed, preferably + in ISO 639-2 format.

In such a case, it is possible to set up the + * parent struct to export a child's options. To do that, simply + * implement AVClass.child_next() and AVClass.child_class_next() in the + * parent struct's AVClass. + * Assuming that the test_struct from above now also contains a + * child_struct field: + * + * @code + * typedef struct child_struct { + * AVClass *class; + * int flags_opt; + * } child_struct; + * static const AVOption child_opts[] = { + * { "test_flags", "This is a test option of flags type.", + * offsetof(child_struct, flags_opt), AV_OPT_TYPE_FLAGS, { .i64 = 0 }, INT_MIN, INT_MAX }, + * { NULL }, + * }; + * static const AVClass child_class = { + * .class_name = "child class", + * .item_name = av_default_item_name, + * .option = child_opts, + * .version = LIBAVUTIL_VERSION_INT, + * }; + * + * void *child_next(void *obj, void *prev) + * { + * test_struct *t = obj; + * if (!prev && t->child_struct) + * return t->child_struct; + * return NULL + * } + * const AVClass child_class_next(const AVClass *prev) + * { + * return prev ? NULL : &child_class; + * } + * @endcode + * Putting child_next() and child_class_next() as defined above into + * test_class will now make child_struct's options accessible through + * test_struct (again, proper setup as described above needs to be done on + * child_struct right after it is created). + * + * From the above example it might not be clear why both child_next() + * and child_class_next() are needed. The distinction is that child_next() + * iterates over actually existing objects, while child_class_next() + * iterates over all possible child classes. E.g. if an AVCodecContext + * was initialized to use a codec which has private options, then its + * child_next() will return AVCodecContext.priv_data and finish + * iterating. OTOH child_class_next() on AVCodecContext.av_class will + * iterate over all available codecs with private options. + * + * @subsection avoptions_implement_named_constants Named constants + * It is possible to create named constants for options. Simply set the unit + * field of the option the constants should apply to a string and + * create the constants themselves as options of type AV_OPT_TYPE_CONST + * with their unit field set to the same string. + * Their default_val field should contain the value of the named + * constant. + * For example, to add some named constants for the test_flags option + * above, put the following into the child_opts array: + * @code + * { "test_flags", "This is a test option of flags type.", + * offsetof(child_struct, flags_opt), AV_OPT_TYPE_FLAGS, { .i64 = 0 }, INT_MIN, INT_MAX, "test_unit" }, + * { "flag1", "This is a flag with value 16", 0, AV_OPT_TYPE_CONST, { .i64 = 16 }, 0, 0, "test_unit" }, + * @endcode + * + * @section avoptions_use Using AVOptions + * This section deals with accessing options in an AVOptions-enabled struct. + * Such structs in FFmpeg are e.g. AVCodecContext in libavcodec or + * AVFormatContext in libavformat. + * + * @subsection avoptions_use_examine Examining AVOptions + * The basic functions for examining options are av_opt_next(), which iterates + * over all options defined for one object, and av_opt_find(), which searches + * for an option with the given name. + * + * The situation is more complicated with nesting. An AVOptions-enabled struct + * may have AVOptions-enabled children. Passing the AV_OPT_SEARCH_CHILDREN flag + * to av_opt_find() will make the function search children recursively. + * + * For enumerating there are basically two cases. The first is when you want to + * get all options that may potentially exist on the struct and its children + * (e.g. when constructing documentation). In that case you should call + * av_opt_child_class_next() recursively on the parent struct's AVClass. The + * second case is when you have an already initialized struct with all its + * children and you want to get all options that can be actually written or read + * from it. In that case you should call av_opt_child_next() recursively (and + * av_opt_next() on each result). + * + * @subsection avoptions_use_get_set Reading and writing AVOptions + * When setting options, you often have a string read directly from the + * user. In such a case, simply passing it to av_opt_set() is enough. For + * non-string type options, av_opt_set() will parse the string according to the + * option type. + * + * Similarly av_opt_get() will read any option type and convert it to a string + * which will be returned.

(libavformat + * always returns refcounted AVPackets, and av_frame_get_buffer() allocates + * refcounted AVFrames.) + * - Receive output in a loop. Periodically call one of the avcodec_receive_*() + * functions and process their output: + * - For decoding, call avcodec_receive_frame(). On success, it will return + * an AVFrame containing uncompressed audio or video data. + * - For encoding, call avcodec_receive_packet(). On success, it will return + * an AVPacket with a compressed frame. + * Repeat this call until it returns AVERROR(EAGAIN) or an error. The + * AVERROR(EAGAIN) return value means that new input data is required to + * return new output. In this case, continue with sending input. For each + * input frame/packet, the codec will typically return 1 output frame/packet, + * but it can also be 0 or more than 1. + * + * At the beginning of decoding or encoding, the codec might accept multiple + * input frames/packets without returning a frame, until its internal buffers + * are filled. This situation is handled transparently if you follow the steps + * outlined above. + * + * In theory, sending input can result in EAGAIN - this should happen only if + * not all output was received. You can use this to structure alternative decode + * or encode loops other than the one suggested above. For example, you could + * try sending new input on each iteration, and try to receive output if that + * returns EAGAIN. + * + * End of stream situations. These require "flushing" (aka draining) the codec, + * as the codec might buffer multiple frames or packets internally for + * performance or out of necessity (consider B-frames). + * This is handled as follows: + * - Instead of valid input, send NULL to the avcodec_send_packet() (decoding) + * or avcodec_send_frame() (encoding) functions. This will enter draining + * mode. + * - Call avcodec_receive_frame() (decoding) or avcodec_receive_packet() + * (encoding) in a loop until AVERROR_EOF is returned. The functions will + * not return AVERROR(EAGAIN), unless you forgot to enter draining mode. + * - Before decoding can be resumed again, the codec has to be reset with + * avcodec_flush_buffers(). + * + * Using the API as outlined above is highly recommended. But it is also + * possible to call functions outside of this rigid schema. For example, you can + * call avcodec_send_packet() repeatedly without calling + * avcodec_receive_frame(). In this case, avcodec_send_packet() will succeed + * until the codec's internal buffer has been filled up (which is typically of + * size 1 per output frame, after initial input), and then reject input with + * AVERROR(EAGAIN). Once it starts rejecting input, you have no choice but to + * read at least some output. + * + * Not all codecs will follow a rigid and predictable dataflow; the only + * guarantee is that an AVERROR(EAGAIN) return value on a send/receive call on + * one end implies that a receive/send call on the other end will succeed, or + * at least will not fail with AVERROR(EAGAIN). In general, no codec will + * permit unlimited buffering of input or output. + * + * This API replaces the following legacy functions: + * - avcodec_decode_video2() and avcodec_decode_audio4(): + * Use avcodec_send_packet() to feed input to the decoder, then use + * avcodec_receive_frame() to receive decoded frames after each packet. + * Unlike with the old video decoding API, multiple frames might result from + * a packet. For audio, splitting the input packet into frames by partially + * decoding packets becomes transparent to the API user. You never need to + * feed an AVPacket to the API twice (unless it is rejected with AVERROR(EAGAIN) - then + * no data was read from the packet). + * Additionally, sending a flush/draining packet is required only once. + * - avcodec_encode_video2()/avcodec_encode_audio2(): + * Use avcodec_send_frame() to feed input to the encoder, then use + * avcodec_receive_packet() to receive encoded packets. + * Providing user-allocated buffers for avcodec_receive_packet() is not + * possible. + * - The new API does not handle subtitles yet. + * + * Mixing new and old function calls on the same AVCodecContext is not allowed, + * and will result in undefined behavior. + * + * Some codecs might require using the new API; using the old API will return + * an error when calling it. All codecs support the new API. + * + * A codec is not allowed to return AVERROR(EAGAIN) for both sending and receiving. This + * would be an invalid state, which could put the codec user into an endless + * loop. The API has no concept of time either: it cannot happen that trying to + * do avcodec_send_packet() results in AVERROR(EAGAIN), but a repeated call 1 second + * later accepts the packet (with no other receive/flush API calls involved). + * The API is a strict state machine, and the passage of time is not supposed + * to influence it. Some timing-dependent behavior might still be deemed + * acceptable in certain cases. But it must never result in both send/receive + * returning EAGAIN at the same time at any point. It must also absolutely be + * avoided that the current state is "unstable" and can "flip-flop" between + * the send/receive APIs allowing progress. For example, it's not allowed that + * the codec randomly decides that it actually wants to consume a packet now + * instead of returning a frame, after it just returned AVERROR(EAGAIN) on an + * avcodec_send_packet() call. + * @} + */ + +/** + * @defgroup lavc_core Core functions/structures. + * @ingroup libavc + * + * Basic definitions, functions for querying libavcodec capabilities, + *

(An + * implication is that this will prefer generic formats over opaque formats + * with arbitrary restrictions, if possible.) + * - Set the width/height fields to the coded frame size, rounded up to the + * API-specific minimum alignment. + * - Only _if_ the hwaccel requires a pre-allocated pool: set the initial_pool_size + * field to the number of maximum reference surfaces possible with the codec, + * plus 1 surface for the user to work (meaning the user can safely reference + * at most 1 decoded surface at a time), plus additional buffering introduced + * by frame threading.

Its main two purposes are demuxing - i.e. splitting a media file + * into component streams, and the reverse process of muxing - writing supplied + * data in a specified container format. It also has an @ref lavf_io + * "I/O module" which supports a number of protocols for accessing the data (e.g. + * file, tcp, http and others). + * Unless you are absolutely sure you won't use libavformat's network + * capabilities, you should also call avformat_network_init(). + * + * A supported input format is described by an AVInputFormat struct, conversely + * an output format is described by AVOutputFormat. You can iterate over all + * input/output formats using the av_demuxer_iterate / av_muxer_iterate() functions. + * The protocols layer is not part of the public API, so you can only get the names + * of supported protocols with the avio_enum_protocols() function. + * + * Main lavf structure used for both muxing and demuxing is AVFormatContext, + * which exports all information about the file being read or written. As with + * most Libavformat structures, its size is not part of public ABI, so it cannot be + * allocated on stack or directly with av_malloc(). To create an + * AVFormatContext, use avformat_alloc_context() (some functions, like + * avformat_open_input() might do that for you). + * + * Most importantly an AVFormatContext contains: + * @li the @ref AVFormatContext.iformat "input" or @ref AVFormatContext.oformat + * "output" format. It is either autodetected or set by user for input; + * always set by user for output. + * @li an @ref AVFormatContext.streams "array" of AVStreams, which describe all + * elementary streams stored in the file. AVStreams are typically referred to + * using their index in this array. + * @li an @ref AVFormatContext.pb "I/O context". It is either opened by lavf or + * set by user for input, always set by user for output (unless you are dealing + * with an AVFMT_NOFILE format). + * + * @section lavf_options Passing options to (de)muxers + * It is possible to configure lavf muxers and demuxers using the @ref avoptions + * mechanism. Generic (format-independent) libavformat options are provided by + * AVFormatContext, they can be examined from a user program by calling + * av_opt_next() / av_opt_find() on an allocated AVFormatContext (or its AVClass + * from avformat_get_class()). Private (format-specific) options are provided by + * AVFormatContext.priv_data if and only if AVInputFormat.priv_class / + * AVOutputFormat.priv_class of the corresponding format struct is non-NULL. + * Further options may be provided by the @ref AVFormatContext.pb "I/O context", + * if its AVClass is non-NULL, and the protocols layer. See the discussion on + * nesting in @ref avoptions documentation to learn how to access those. + * + * @section urls + * URL strings in libavformat are made of a scheme/protocol, a ':', and a + * scheme specific string. URLs without a scheme and ':' used for local files + * are supported but deprecated. "file:" should be used for local files. + * + * It is important that the scheme string is not taken from untrusted + * sources without checks. + * + * Note that some schemes/protocols are quite powerful, allowing access to + * both local and remote files, parts of them, concatenations of them, local + * audio and video devices and so on. + * + * @{ + * + * @defgroup lavf_decoding Demuxing + * @{ + * Demuxers read a media file and split it into chunks of data (@em packets). A + * @ref AVPacket "packet" contains one or more encoded frames which belongs to a + * single elementary stream. In the lavf API this process is represented by the + * avformat_open_input() function for opening a file, av_read_frame() for + * reading a single packet and finally avformat_close_input(), which does the + * cleanup. + * + * @section lavf_decoding_open Opening a media file + * The minimum information required to open a file is its URL, which + * is passed to avformat_open_input(), as in the following code: + * @code + * const char *url = "file:in.mp3"; + * AVFormatContext *s = NULL; + * int ret = avformat_open_input(&s, url, NULL, NULL); + * if (ret < 0) + * abort(); + * @endcode + * The above code attempts to allocate an AVFormatContext, open the + * specified file (autodetecting the format) and read the header, exporting the + * information stored there into s. Some formats do not have a header or do not + * store enough information there, so it is recommended that you call the + * avformat_find_stream_info() function which tries to read and decode a few + * frames to find missing information. + * + * In some cases you might want to preallocate an AVFormatContext yourself with + * avformat_alloc_context() and do some tweaking on it before passing it to + * avformat_open_input(). One such case is when you want to use custom functions + * for reading input data instead of lavf internal I/O layer. + * To do that, create your own AVIOContext with avio_alloc_context(), passing + * your reading callbacks to it. Then set the @em pb field of your + * AVFormatContext to newly created AVIOContext. + * + * Since the format of the opened file is in general not known until after + * avformat_open_input() has returned, it is not possible to set demuxer private + * options on a preallocated context. Instead, the options should be passed to + * avformat_open_input() wrapped in an AVDictionary: + * @code + * AVDictionary *options = NULL; + * av_dict_set(&options, "video_size", "640x480", 0); + * av_dict_set(&options, "pixel_format", "rgb24", 0); + * + * if (avformat_open_input(&s, url, NULL, &options) < 0) + * abort(); + * av_dict_free(&options); + * @endcode + * This code passes the private options 'video_size' and 'pixel_format' to the + * demuxer. They would be necessary for e.g. the rawvideo demuxer, since it + * cannot know how to interpret raw video data otherwise. If the format turns + * out to be something different than raw video, those options will not be + * recognized by the demuxer and therefore will not be applied. Such unrecognized + * options are then returned in the options dictionary (recognized options are + * consumed). The calling program can handle such unrecognized options as it + * wishes, e.g. + * @code + * AVDictionaryEntry *e; + * if (e = av_dict_get(options, "", NULL, AV_DICT_IGNORE_SUFFIX)) { + * fprintf(stderr, "Option %s not recognized by the demuxer.\n", e->key); + * abort(); + * } + * @endcode + * + * After you have finished reading the file, you must close it with + * avformat_close_input(). It will free everything associated with the file. + * + * @section lavf_decoding_read Reading from an opened file + * Reading data from an opened AVFormatContext is done by repeatedly calling + * av_read_frame() on it. Each call, if successful, will return an AVPacket + * containing encoded data for one AVStream, identified by + * AVPacket.stream_index. This packet may be passed straight into the libavcodec + * decoding functions avcodec_send_packet() or avcodec_decode_subtitle2() if the + * caller wishes to decode the data. + * + * AVPacket.pts, AVPacket.dts and AVPacket.duration timing information will be + * set if known. They may also be unset (i.e. AV_NOPTS_VALUE for + * pts/dts, 0 for duration) if the stream does not provide them. The timing + * information will be in AVStream.time_base units, i.e. it has to be + * multiplied by the timebase to convert them to seconds. + * + * If AVPacket.buf is set on the returned packet, then the packet is + * allocated dynamically and the user may keep it indefinitely. + * Otherwise, if AVPacket.buf is NULL, the packet data is backed by a + * static storage somewhere inside the demuxer and the packet is only valid + * until the next av_read_frame() call or closing the file. If the caller + * requires a longer lifetime, av_packet_make_refcounted() will ensure that + * the data is reference counted, copying the data if necessary. + * In both cases, the packet must be freed with av_packet_unref() when it is no + * longer needed. + * + * @section lavf_decoding_seek Seeking + * @} + * + * @defgroup lavf_encoding Muxing + * @{ + * Muxers take encoded data in the form of @ref AVPacket "AVPackets" and write + * it into files or other output bytestreams in the specified container format. + * + * The main API functions for muxing are avformat_write_header() for writing the + * file header, av_write_frame() / av_interleaved_write_frame() for writing the + * packets and av_write_trailer() for finalizing the file. + * + * At the beginning of the muxing process, the caller must first call + * avformat_alloc_context() to create a muxing context. The caller then sets up + * the muxer by filling the various fields in this context: + * + * - The @ref AVFormatContext.oformat "oformat" field must be set to select the + * muxer that will be used. + * - Unless the format is of the AVFMT_NOFILE type, the @ref AVFormatContext.pb + * "pb" field must be set to an opened IO context, either returned from + * avio_open2() or a custom one. + * - Unless the format is of the AVFMT_NOSTREAMS type, at least one stream must + * be created with the avformat_new_stream() function. The caller should fill + * the @ref AVStream.codecpar "stream codec parameters" information, such as the + * codec @ref AVCodecParameters.codec_type "type", @ref AVCodecParameters.codec_id + * "id" and other parameters (e.g. width / height, the pixel or sample format, + * etc.) as known. The @ref AVStream.time_base "stream timebase" should + * be set to the timebase that the caller desires to use for this stream (note + * that the timebase actually used by the muxer can be different, as will be + * described later). + * - It is advised to manually initialize only the relevant fields in + * AVCodecParameters, rather than using @ref avcodec_parameters_copy() during + * remuxing: there is no guarantee that the codec context values remain valid + * for both input and output format contexts. + * - The caller may fill in additional information, such as @ref + * AVFormatContext.metadata "global" or @ref AVStream.metadata "per-stream" + * metadata, @ref AVFormatContext.chapters "chapters", @ref + * AVFormatContext.programs "programs", etc. as described in the + * AVFormatContext documentation. Whether such information will actually be + * stored in the output depends on what the container format and the muxer + * support. + * + * When the muxing context is fully set up, the caller must call + * avformat_write_header() to initialize the muxer internals and write the file + * header. Whether anything actually is written to the IO context at this step + * depends on the muxer, but this function must always be called. Any muxer + * private options must be passed in the options parameter to this function. + * + * The data is then sent to the muxer by repeatedly calling av_write_frame() or + * av_interleaved_write_frame() (consult those functions' documentation for + * discussion on the difference between them; only one of them may be used with + * a single muxing context, they should not be mixed). Do note that the timing + * information on the packets sent to the muxer must be in the corresponding + * AVStream's timebase. That timebase is set by the muxer (in the + * avformat_write_header() step) and may be different from the timebase + * requested by the caller. + * + * Once all the data has been written, the caller must call av_write_trailer() + * to flush any buffered packets and finalize the output file, then close the IO + * context (if any) and finally free the muxing context with + * avformat_free_context(). + * @} + * + * @defgroup lavf_io I/O Read/Write + * @{ + * @section lavf_io_dirlist Directory listing + * The directory listing API makes it possible to list files on remote servers. + * + * Some of possible use cases: + * - an "open file" dialog to choose files from a remote location, + * - a recursive media finder providing a player with an ability to play all + * files from a given directory. + * + * @subsection lavf_io_dirlist_open Opening a directory + * At first, a directory needs to be opened by calling avio_open_dir() + * supplied with a URL and, optionally, ::AVDictionary containing + * protocol-specific parameters.

Conversely it allows a client application to + * set metadata when muxing. + * + * Metadata is exported or set as pairs of key/value strings in the 'metadata' + * fields of the AVFormatContext, AVStream, AVChapter and AVProgram structs + * using the @ref lavu_dict "AVDictionary" API. Like all strings in FFmpeg, + * metadata is assumed to be UTF-8 encoded Unicode. Note that metadata + * exported by demuxers isn't checked to be valid UTF-8 in most cases. + * + * Important concepts to keep in mind: + * - Keys are unique; there can never be 2 tags with the same key. This is + * also meant semantically, i.e., a demuxer should not knowingly produce + * several keys that are literally different but semantically identical. + * E.g., key=Author5, key=Author6. In this example, all authors must be + * placed in the same tag. + * - Metadata is flat, not hierarchical; there are no subtags. If you + * want to store, e.g., the email address of the child of producer Alice + * and actor Bob, that could have key=alice_and_bobs_childs_email_address. + * - Several modifiers can be applied to the tag name. This is done by + * appending a dash character ('-') and the modifier name in the order + * they appear in the list below -- e.g. foo-eng-sort, not foo-sort-eng. + * - language -- a tag whose value is localized for a particular language + * is appended with the ISO 639-2/B 3-letter language code. + * For example: Author-ger=Michael, Author-eng=Mike + * The original/default language is in the unqualified "Author" tag. + * A demuxer should set a default if it sets any translated tag. + * - sorting -- a modified version of a tag that should be used for + * sorting will have '-sort' appended. E.g. artist="The Beatles", + * artist-sort="Beatles, The". + * - Some protocols and demuxers support metadata updates.

An option can have a help text, a type and a range of possible + * values. Options may then be enumerated, read and written to. + * + * @section avoptions_implement Implementing AVOptions + * This section describes how to add AVOptions capabilities to a struct. + * + * All AVOptions-related information is stored in an AVClass. Therefore + * the first member of the struct should be a pointer to an AVClass describing it. + * The option field of the AVClass must be set to a NULL-terminated static array + * of AVOptions. Each AVOption must have a non-empty name, a type, a default + * value and for number-type AVOptions also a range of allowed values. It must + * also declare an offset in bytes from the start of the struct, where the field + * associated with this AVOption is located. Other fields in the AVOption struct + * should also be set when applicable, but are not required. + * + * The following example illustrates an AVOptions-enabled struct: + * @code + * typedef struct test_struct { + * const AVClass *class; + * int int_opt; + * char *str_opt; + * uint8_t *bin_opt; + * int bin_len; + * } test_struct; + * + * static const AVOption test_options[] = { + * { "test_int", "This is a test option of int type.", offsetof(test_struct, int_opt), + * AV_OPT_TYPE_INT, { .i64 = -1 }, INT_MIN, INT_MAX }, + * { "test_str", "This is a test option of string type.", offsetof(test_struct, str_opt), + * AV_OPT_TYPE_STRING }, + * { "test_bin", "This is a test option of binary type.", offsetof(test_struct, bin_opt), + * AV_OPT_TYPE_BINARY }, + * { NULL }, + * }; + * + * static const AVClass test_class = { + * .class_name = "test class", + * .item_name = av_default_item_name, + * .option = test_options, + * .version = LIBAVUTIL_VERSION_INT, + * }; + * @endcode + * + * Next, when allocating your struct, you must ensure that the AVClass pointer + * is set to the correct value. Then, av_opt_set_defaults() can be called to + * initialize defaults. After that the struct is ready to be used with the + * AVOptions API. + * + * When cleaning up, you may use the av_opt_free() function to automatically + * free all the allocated string and binary options. + * + * Continuing with the above example: + * + * @code + * test_struct *alloc_test_struct(void) + * { + * test_struct *ret = av_mallocz(sizeof(*ret)); + * ret->class = &test_class; + * av_opt_set_defaults(ret); + * return ret; + * } + * void free_test_struct(test_struct **foo) + * { + * av_opt_free(*foo); + * av_freep(foo); + * } + * @endcode + * + * @subsection avoptions_implement_nesting Nesting + * It may happen that an AVOptions-enabled struct contains another + * AVOptions-enabled struct as a member (e.g. AVCodecContext in + * libavcodec exports generic options, while its priv_data field exports + * codec-specific options). In such a case, it is possible to set up the + * parent struct to export a child's options. To do that, simply + * implement AVClass.child_next() and AVClass.child_class_next() in the + * parent struct's AVClass. + * Assuming that the test_struct from above now also contains a + * child_struct field: + * + * @code + * typedef struct child_struct { + * AVClass *class; + * int flags_opt; + * } child_struct; + * static const AVOption child_opts[] = { + * { "test_flags", "This is a test option of flags type.", + * offsetof(child_struct, flags_opt), AV_OPT_TYPE_FLAGS, { .i64 = 0 }, INT_MIN, INT_MAX }, + * { NULL }, + * }; + * static const AVClass child_class = { + * .class_name = "child class", + * .item_name = av_default_item_name, + * .option = child_opts, + * .version = LIBAVUTIL_VERSION_INT, + * }; + * + * void *child_next(void *obj, void *prev) + * { + * test_struct *t = obj; + * if (!prev && t->child_struct) + * return t->child_struct; + * return NULL + * } + * const AVClass child_class_next(const AVClass *prev) + * { + * return prev ? NULL : &child_class; + * } + * @endcode + * Putting child_next() and child_class_next() as defined above into + * test_class will now make child_struct's options accessible through + * test_struct (again, proper setup as described above needs to be done on + * child_struct right after it is created). + * + * From the above example it might not be clear why both child_next() + * and child_class_next() are needed. The distinction is that child_next() + * iterates over actually existing objects, while child_class_next() + * iterates over all possible child classes. E.g. if an AVCodecContext + * was initialized to use a codec which has private options, then its + * child_next() will return AVCodecContext.priv_data and finish + * iterating. OTOH child_class_next() on AVCodecContext.av_class will + * iterate over all available codecs with private options. + * + * @subsection avoptions_implement_named_constants Named constants + * It is possible to create named constants for options. Simply set the unit + * field of the option the constants should apply to a string and + * create the constants themselves as options of type AV_OPT_TYPE_CONST + * with their unit field set to the same string. + * Their default_val field should contain the value of the named + * constant. + * For example, to add some named constants for the test_flags option + * above, put the following into the child_opts array: + * @code + * { "test_flags", "This is a test option of flags type.", + * offsetof(child_struct, flags_opt), AV_OPT_TYPE_FLAGS, { .i64 = 0 }, INT_MIN, INT_MAX, "test_unit" }, + * { "flag1", "This is a flag with value 16", 0, AV_OPT_TYPE_CONST, { .i64 = 16 }, 0, 0, "test_unit" }, + * @endcode + * + * @section avoptions_use Using AVOptions + * This section deals with accessing options in an AVOptions-enabled struct. + * Such structs in FFmpeg are e.g. AVCodecContext in libavcodec or + * AVFormatContext in libavformat. + * + * @subsection avoptions_use_examine Examining AVOptions + * The basic functions for examining options are av_opt_next(), which iterates + * over all options defined for one object, and av_opt_find(), which searches + * for an option with the given name. + * + * The situation is more complicated with nesting. An AVOptions-enabled struct + * may have AVOptions-enabled children. Passing the AV_OPT_SEARCH_CHILDREN flag + * to av_opt_find() will make the function search children recursively. + * + * For enumerating there are basically two cases. The first is when you want to + * get all options that may potentially exist on the struct and its children + * (e.g. when constructing documentation). In that case you should call + * av_opt_child_class_next() recursively on the parent struct's AVClass. The + * second case is when you have an already initialized struct with all its + * children and you want to get all options that can be actually written or read + * from it. In that case you should call av_opt_child_next() recursively (and + * av_opt_next() on each result). + * + * @subsection avoptions_use_get_set Reading and writing AVOptions + * When setting options, you often have a string read directly from the + * user. In such a case, simply passing it to av_opt_set() is enough. For + * non-string type options, av_opt_set() will parse the string according to the + * option type. + * + * Similarly av_opt_get() will read any option type and convert it to a string + * which will be returned. Do not forget that the string is allocated, so you + * have to free it with av_free(). + * + * In some cases it may be more convenient to put all options into an + * AVDictionary and call av_opt_set_dict() on it. A specific case of this + * are the format/codec open functions in lavf/lavc which take a dictionary + * filled with option as a parameter. This makes it possible to set some options + * that cannot be set otherwise, since e.g. the input file format is not known + * before the file is actually opened. + */ + +enum AVOptionType{ + AV_OPT_TYPE_FLAGS, + AV_OPT_TYPE_INT, + AV_OPT_TYPE_INT64, + AV_OPT_TYPE_DOUBLE, + AV_OPT_TYPE_FLOAT, + AV_OPT_TYPE_STRING, + AV_OPT_TYPE_RATIONAL, + AV_OPT_TYPE_BINARY, ///< offset must point to a pointer immediately followed by an int for the length + AV_OPT_TYPE_DICT, + AV_OPT_TYPE_UINT64, + AV_OPT_TYPE_CONST, + AV_OPT_TYPE_IMAGE_SIZE, ///< offset must point to two consecutive integers + AV_OPT_TYPE_PIXEL_FMT, + AV_OPT_TYPE_SAMPLE_FMT, + AV_OPT_TYPE_VIDEO_RATE, ///< offset must point to AVRational + AV_OPT_TYPE_DURATION, + AV_OPT_TYPE_COLOR, + AV_OPT_TYPE_CHANNEL_LAYOUT, + AV_OPT_TYPE_BOOL, +}; + +/** + * AVOption + */ +typedef struct AVOption { + const char *name; + + /** + * short English help text + * @todo What about other languages? + */ + const char *help; + + /** + * The offset relative to the context structure where the option + * value is stored.

(libavformat + * always returns refcounted AVPackets, and av_frame_get_buffer() allocates + * refcounted AVFrames.) + * - Receive output in a loop. Periodically call one of the avcodec_receive_*() + * functions and process their output: + * - For decoding, call avcodec_receive_frame(). On success, it will return + * an AVFrame containing uncompressed audio or video data. + * - For encoding, call avcodec_receive_packet(). On success, it will return + * an AVPacket with a compressed frame. + * Repeat this call until it returns AVERROR(EAGAIN) or an error. The + * AVERROR(EAGAIN) return value means that new input data is required to + * return new output. In this case, continue with sending input. For each + * input frame/packet, the codec will typically return 1 output frame/packet, + * but it can also be 0 or more than 1. + * + * At the beginning of decoding or encoding, the codec might accept multiple + * input frames/packets without returning a frame, until its internal buffers + * are filled. This situation is handled transparently if you follow the steps + * outlined above. + * + * In theory, sending input can result in EAGAIN - this should happen only if + * not all output was received. You can use this to structure alternative decode + * or encode loops other than the one suggested above. For example, you could + * try sending new input on each iteration, and try to receive output if that + * returns EAGAIN. + * + * End of stream situations. These require "flushing" (aka draining) the codec, + * as the codec might buffer multiple frames or packets internally for + * performance or out of necessity (consider B-frames). + * This is handled as follows: + * - Instead of valid input, send NULL to the avcodec_send_packet() (decoding) + * or avcodec_send_frame() (encoding) functions. This will enter draining + * mode. + * - Call avcodec_receive_frame() (decoding) or avcodec_receive_packet() + * (encoding) in a loop until AVERROR_EOF is returned. The functions will + * not return AVERROR(EAGAIN), unless you forgot to enter draining mode. + * - Before decoding can be resumed again, the codec has to be reset with + * avcodec_flush_buffers(). + * + * Using the API as outlined above is highly recommended. But it is also + * possible to call functions outside of this rigid schema. For example, you can + * call avcodec_send_packet() repeatedly without calling + * avcodec_receive_frame(). In this case, avcodec_send_packet() will succeed + * until the codec's internal buffer has been filled up (which is typically of + * size 1 per output frame, after initial input), and then reject input with + * AVERROR(EAGAIN). Once it starts rejecting input, you have no choice but to + * read at least some output. + * + * Not all codecs will follow a rigid and predictable dataflow; the only + * guarantee is that an AVERROR(EAGAIN) return value on a send/receive call on + * one end implies that a receive/send call on the other end will succeed, or + * at least will not fail with AVERROR(EAGAIN). In general, no codec will + * permit unlimited buffering of input or output. + * + * This API replaces the following legacy functions: + * - avcodec_decode_video2() and avcodec_decode_audio4(): + * Use avcodec_send_packet() to feed input to the decoder, then use + * avcodec_receive_frame() to receive decoded frames after each packet. + * Unlike with the old video decoding API, multiple frames might result from + * a packet. For audio, splitting the input packet into frames by partially + * decoding packets becomes transparent to the API user. You never need to + * feed an AVPacket to the API twice (unless it is rejected with AVERROR(EAGAIN) - then + * no data was read from the packet). + * Additionally, sending a flush/draining packet is required only once. + * - avcodec_encode_video2()/avcodec_encode_audio2(): + * Use avcodec_send_frame() to feed input to the encoder, then use + * avcodec_receive_packet() to receive encoded packets. + * Providing user-allocated buffers for avcodec_receive_packet() is not + * possible. + * - The new API does not handle subtitles yet. + * + * Mixing new and old function calls on the same AVCodecContext is not allowed, + * and will result in undefined behavior. + * + * Some codecs might require using the new API; using the old API will return + * an error when calling it. All codecs support the new API. + * + * A codec is not allowed to return AVERROR(EAGAIN) for both sending and receiving. This + * would be an invalid state, which could put the codec user into an endless + * loop. The API has no concept of time either: it cannot happen that trying to + * do avcodec_send_packet() results in AVERROR(EAGAIN), but a repeated call 1 second + * later accepts the packet (with no other receive/flush API calls involved). + * The API is a strict state machine, and the passage of time is not supposed + * to influence it. Some timing-dependent behavior might still be deemed + * acceptable in certain cases. But it must never result in both send/receive + * returning EAGAIN at the same time at any point. It must also absolutely be + * avoided that the current state is "unstable" and can "flip-flop" between + * the send/receive APIs allowing progress. For example, it's not allowed that + * the codec randomly decides that it actually wants to consume a packet now + * instead of returning a frame, after it just returned AVERROR(EAGAIN) on an + * avcodec_send_packet() call. + * @} + */ + +/** + * @defgroup lavc_core Core functions/structures. + * @ingroup libavc + * + * Basic definitions, functions for querying libavcodec capabilities, + *

(An + * implication is that this will prefer generic formats over opaque formats + * with arbitrary restrictions, if possible.) + * - Set the width/height fields to the coded frame size, rounded up to the + * API-specific minimum alignment. + * - Only _if_ the hwaccel requires a pre-allocated pool: set the initial_pool_size + * field to the number of maximum reference surfaces possible with the codec, + * plus 1 surface for the user to work (meaning the user can safely reference + * at most 1 decoded surface at a time), plus additional buffering introduced + * by frame threading.

Its main two purposes are demuxing - i.e. splitting a media file + * into component streams, and the reverse process of muxing - writing supplied + * data in a specified container format. It also has an @ref lavf_io + * "I/O module" which supports a number of protocols for accessing the data (e.g. + * file, tcp, http and others). + * Unless you are absolutely sure you won't use libavformat's network + * capabilities, you should also call avformat_network_init(). + * + * A supported input format is described by an AVInputFormat struct, conversely + * an output format is described by AVOutputFormat. You can iterate over all + * input/output formats using the av_demuxer_iterate / av_muxer_iterate() functions. + * The protocols layer is not part of the public API, so you can only get the names + * of supported protocols with the avio_enum_protocols() function. + * + * Main lavf structure used for both muxing and demuxing is AVFormatContext, + * which exports all information about the file being read or written. As with + * most Libavformat structures, its size is not part of public ABI, so it cannot be + * allocated on stack or directly with av_malloc(). To create an + * AVFormatContext, use avformat_alloc_context() (some functions, like + * avformat_open_input() might do that for you). + * + * Most importantly an AVFormatContext contains: + * @li the @ref AVFormatContext.iformat "input" or @ref AVFormatContext.oformat + * "output" format. It is either autodetected or set by user for input; + * always set by user for output. + * @li an @ref AVFormatContext.streams "array" of AVStreams, which describe all + * elementary streams stored in the file. AVStreams are typically referred to + * using their index in this array. + * @li an @ref AVFormatContext.pb "I/O context". It is either opened by lavf or + * set by user for input, always set by user for output (unless you are dealing + * with an AVFMT_NOFILE format). + * + * @section lavf_options Passing options to (de)muxers + * It is possible to configure lavf muxers and demuxers using the @ref avoptions + * mechanism. Generic (format-independent) libavformat options are provided by + * AVFormatContext, they can be examined from a user program by calling + * av_opt_next() / av_opt_find() on an allocated AVFormatContext (or its AVClass + * from avformat_get_class()). Private (format-specific) options are provided by + * AVFormatContext.priv_data if and only if AVInputFormat.priv_class / + * AVOutputFormat.priv_class of the corresponding format struct is non-NULL. + * Further options may be provided by the @ref AVFormatContext.pb "I/O context", + * if its AVClass is non-NULL, and the protocols layer. See the discussion on + * nesting in @ref avoptions documentation to learn how to access those. + * + * @section urls + * URL strings in libavformat are made of a scheme/protocol, a ':', and a + * scheme specific string. URLs without a scheme and ':' used for local files + * are supported but deprecated. "file:" should be used for local files. + * + * It is important that the scheme string is not taken from untrusted + * sources without checks. + * + * Note that some schemes/protocols are quite powerful, allowing access to + * both local and remote files, parts of them, concatenations of them, local + * audio and video devices and so on. + * + * @{ + * + * @defgroup lavf_decoding Demuxing + * @{ + * Demuxers read a media file and split it into chunks of data (@em packets). A + * @ref AVPacket "packet" contains one or more encoded frames which belongs to a + * single elementary stream. In the lavf API this process is represented by the + * avformat_open_input() function for opening a file, av_read_frame() for + * reading a single packet and finally avformat_close_input(), which does the + * cleanup. + * + * @section lavf_decoding_open Opening a media file + * The minimum information required to open a file is its URL, which + * is passed to avformat_open_input(), as in the following code: + * @code + * const char *url = "file:in.mp3"; + * AVFormatContext *s = NULL; + * int ret = avformat_open_input(&s, url, NULL, NULL); + * if (ret < 0) + * abort(); + * @endcode + * The above code attempts to allocate an AVFormatContext, open the + * specified file (autodetecting the format) and read the header, exporting the + * information stored there into s. Some formats do not have a header or do not + * store enough information there, so it is recommended that you call the + * avformat_find_stream_info() function which tries to read and decode a few + * frames to find missing information. + * + * In some cases you might want to preallocate an AVFormatContext yourself with + * avformat_alloc_context() and do some tweaking on it before passing it to + * avformat_open_input(). One such case is when you want to use custom functions + * for reading input data instead of lavf internal I/O layer. + * To do that, create your own AVIOContext with avio_alloc_context(), passing + * your reading callbacks to it. Then set the @em pb field of your + * AVFormatContext to newly created AVIOContext. + * + * Since the format of the opened file is in general not known until after + * avformat_open_input() has returned, it is not possible to set demuxer private + * options on a preallocated context. Instead, the options should be passed to + * avformat_open_input() wrapped in an AVDictionary: + * @code + * AVDictionary *options = NULL; + * av_dict_set(&options, "video_size", "640x480", 0); + * av_dict_set(&options, "pixel_format", "rgb24", 0); + * + * if (avformat_open_input(&s, url, NULL, &options) < 0) + * abort(); + * av_dict_free(&options); + * @endcode + * This code passes the private options 'video_size' and 'pixel_format' to the + * demuxer. They would be necessary for e.g. the rawvideo demuxer, since it + * cannot know how to interpret raw video data otherwise. If the format turns + * out to be something different than raw video, those options will not be + * recognized by the demuxer and therefore will not be applied. Such unrecognized + * options are then returned in the options dictionary (recognized options are + * consumed). The calling program can handle such unrecognized options as it + * wishes, e.g. + * @code + * AVDictionaryEntry *e; + * if (e = av_dict_get(options, "", NULL, AV_DICT_IGNORE_SUFFIX)) { + * fprintf(stderr, "Option %s not recognized by the demuxer.\n", e->key); + * abort(); + * } + * @endcode + * + * After you have finished reading the file, you must close it with + * avformat_close_input(). It will free everything associated with the file. + * + * @section lavf_decoding_read Reading from an opened file + * Reading data from an opened AVFormatContext is done by repeatedly calling + * av_read_frame() on it. Each call, if successful, will return an AVPacket + * containing encoded data for one AVStream, identified by + * AVPacket.stream_index. This packet may be passed straight into the libavcodec + * decoding functions avcodec_send_packet() or avcodec_decode_subtitle2() if the + * caller wishes to decode the data. + * + * AVPacket.pts, AVPacket.dts and AVPacket.duration timing information will be + * set if known. They may also be unset (i.e. AV_NOPTS_VALUE for + * pts/dts, 0 for duration) if the stream does not provide them. The timing + * information will be in AVStream.time_base units, i.e. it has to be + * multiplied by the timebase to convert them to seconds. + * + * If AVPacket.buf is set on the returned packet, then the packet is + * allocated dynamically and the user may keep it indefinitely. + * Otherwise, if AVPacket.buf is NULL, the packet data is backed by a + * static storage somewhere inside the demuxer and the packet is only valid + * until the next av_read_frame() call or closing the file. If the caller + * requires a longer lifetime, av_packet_make_refcounted() will ensure that + * the data is reference counted, copying the data if necessary. + * In both cases, the packet must be freed with av_packet_unref() when it is no + * longer needed. + * + * @section lavf_decoding_seek Seeking + * @} + * + * @defgroup lavf_encoding Muxing + * @{ + * Muxers take encoded data in the form of @ref AVPacket "AVPackets" and write + * it into files or other output bytestreams in the specified container format. + * + * The main API functions for muxing are avformat_write_header() for writing the + * file header, av_write_frame() / av_interleaved_write_frame() for writing the + * packets and av_write_trailer() for finalizing the file. + * + * At the beginning of the muxing process, the caller must first call + * avformat_alloc_context() to create a muxing context. The caller then sets up + * the muxer by filling the various fields in this context: + * + * - The @ref AVFormatContext.oformat "oformat" field must be set to select the + * muxer that will be used. + * - Unless the format is of the AVFMT_NOFILE type, the @ref AVFormatContext.pb + * "pb" field must be set to an opened IO context, either returned from + * avio_open2() or a custom one. + * - Unless the format is of the AVFMT_NOSTREAMS type, at least one stream must + * be created with the avformat_new_stream() function. The caller should fill + * the @ref AVStream.codecpar "stream codec parameters" information, such as the + * codec @ref AVCodecParameters.codec_type "type", @ref AVCodecParameters.codec_id + * "id" and other parameters (e.g. width / height, the pixel or sample format, + * etc.) as known. The @ref AVStream.time_base "stream timebase" should + * be set to the timebase that the caller desires to use for this stream (note + * that the timebase actually used by the muxer can be different, as will be + * described later). + * - It is advised to manually initialize only the relevant fields in + * AVCodecParameters, rather than using @ref avcodec_parameters_copy() during + * remuxing: there is no guarantee that the codec context values remain valid + * for both input and output format contexts. + * - The caller may fill in additional information, such as @ref + * AVFormatContext.metadata "global" or @ref AVStream.metadata "per-stream" + * metadata, @ref AVFormatContext.chapters "chapters", @ref + * AVFormatContext.programs "programs", etc. as described in the + * AVFormatContext documentation. Whether such information will actually be + * stored in the output depends on what the container format and the muxer + * support. + * + * When the muxing context is fully set up, the caller must call + * avformat_write_header() to initialize the muxer internals and write the file + * header. Whether anything actually is written to the IO context at this step + * depends on the muxer, but this function must always be called. Any muxer + * private options must be passed in the options parameter to this function. + * + * The data is then sent to the muxer by repeatedly calling av_write_frame() or + * av_interleaved_write_frame() (consult those functions' documentation for + * discussion on the difference between them; only one of them may be used with + * a single muxing context, they should not be mixed). Do note that the timing + * information on the packets sent to the muxer must be in the corresponding + * AVStream's timebase. That timebase is set by the muxer (in the + * avformat_write_header() step) and may be different from the timebase + * requested by the caller. + * + * Once all the data has been written, the caller must call av_write_trailer() + * to flush any buffered packets and finalize the output file, then close the IO + * context (if any) and finally free the muxing context with + * avformat_free_context(). + * @} + * + * @defgroup lavf_io I/O Read/Write + * @{ + * @section lavf_io_dirlist Directory listing + * The directory listing API makes it possible to list files on remote servers. + * + * Some of possible use cases: + * - an "open file" dialog to choose files from a remote location, + * - a recursive media finder providing a player with an ability to play all + * files from a given directory. + * + * @subsection lavf_io_dirlist_open Opening a directory + * At first, a directory needs to be opened by calling avio_open_dir() + * supplied with a URL and, optionally, ::AVDictionary containing + * protocol-specific parameters.

Conversely it allows a client application to + * set metadata when muxing. + * + * Metadata is exported or set as pairs of key/value strings in the 'metadata' + * fields of the AVFormatContext, AVStream, AVChapter and AVProgram structs + * using the @ref lavu_dict "AVDictionary" API. Like all strings in FFmpeg, + * metadata is assumed to be UTF-8 encoded Unicode. Note that metadata + * exported by demuxers isn't checked to be valid UTF-8 in most cases. + * + * Important concepts to keep in mind: + * - Keys are unique; there can never be 2 tags with the same key. This is + * also meant semantically, i.e., a demuxer should not knowingly produce + * several keys that are literally different but semantically identical. + * E.g., key=Author5, key=Author6. In this example, all authors must be + * placed in the same tag. + * - Metadata is flat, not hierarchical; there are no subtags. If you + * want to store, e.g., the email address of the child of producer Alice + * and actor Bob, that could have key=alice_and_bobs_childs_email_address. + * - Several modifiers can be applied to the tag name. This is done by + * appending a dash character ('-') and the modifier name in the order + * they appear in the list below -- e.g. foo-eng-sort, not foo-sort-eng. + * - language -- a tag whose value is localized for a particular language + * is appended with the ISO 639-2/B 3-letter language code. + * For example: Author-ger=Michael, Author-eng=Mike + * The original/default language is in the unqualified "Author" tag. + * A demuxer should set a default if it sets any translated tag. + * - sorting -- a modified version of a tag that should be used for + * sorting will have '-sort' appended. E.g. artist="The Beatles", + * artist-sort="Beatles, The". + * - Some protocols and demuxers support metadata updates.

An option can have a help text, a type and a range of possible + * values. Options may then be enumerated, read and written to. + * + * @section avoptions_implement Implementing AVOptions + * This section describes how to add AVOptions capabilities to a struct. + * + * All AVOptions-related information is stored in an AVClass. Therefore + * the first member of the struct should be a pointer to an AVClass describing it. + * The option field of the AVClass must be set to a NULL-terminated static array + * of AVOptions. Each AVOption must have a non-empty name, a type, a default + * value and for number-type AVOptions also a range of allowed values. It must + * also declare an offset in bytes from the start of the struct, where the field + * associated with this AVOption is located. Other fields in the AVOption struct + * should also be set when applicable, but are not required. + * + * The following example illustrates an AVOptions-enabled struct: + * @code + * typedef struct test_struct { + * const AVClass *class; + * int int_opt; + * char *str_opt; + * uint8_t *bin_opt; + * int bin_len; + * } test_struct; + * + * static const AVOption test_options[] = { + * { "test_int", "This is a test option of int type.", offsetof(test_struct, int_opt), + * AV_OPT_TYPE_INT, { .i64 = -1 }, INT_MIN, INT_MAX }, + * { "test_str", "This is a test option of string type.", offsetof(test_struct, str_opt), + * AV_OPT_TYPE_STRING }, + * { "test_bin", "This is a test option of binary type.", offsetof(test_struct, bin_opt), + * AV_OPT_TYPE_BINARY }, + * { NULL }, + * }; + * + * static const AVClass test_class = { + * .class_name = "test class", + * .item_name = av_default_item_name, + * .option = test_options, + * .version = LIBAVUTIL_VERSION_INT, + * }; + * @endcode + * + * Next, when allocating your struct, you must ensure that the AVClass pointer + * is set to the correct value. Then, av_opt_set_defaults() can be called to + * initialize defaults. After that the struct is ready to be used with the + * AVOptions API. + * + * When cleaning up, you may use the av_opt_free() function to automatically + * free all the allocated string and binary options. + * + * Continuing with the above example: + * + * @code + * test_struct *alloc_test_struct(void) + * { + * test_struct *ret = av_mallocz(sizeof(*ret)); + * ret->class = &test_class; + * av_opt_set_defaults(ret); + * return ret; + * } + * void free_test_struct(test_struct **foo) + * { + * av_opt_free(*foo); + * av_freep(foo); + * } + * @endcode + * + * @subsection avoptions_implement_nesting Nesting + * It may happen that an AVOptions-enabled struct contains another + * AVOptions-enabled struct as a member (e.g. AVCodecContext in + * libavcodec exports generic options, while its priv_data field exports + * codec-specific options). In such a case, it is possible to set up the + * parent struct to export a child's options. To do that, simply + * implement AVClass.child_next() and AVClass.child_class_next() in the + * parent struct's AVClass. + * Assuming that the test_struct from above now also contains a + * child_struct field: + * + * @code + * typedef struct child_struct { + * AVClass *class; + * int flags_opt; + * } child_struct; + * static const AVOption child_opts[] = { + * { "test_flags", "This is a test option of flags type.", + * offsetof(child_struct, flags_opt), AV_OPT_TYPE_FLAGS, { .i64 = 0 }, INT_MIN, INT_MAX }, + * { NULL }, + * }; + * static const AVClass child_class = { + * .class_name = "child class", + * .item_name = av_default_item_name, + * .option = child_opts, + * .version = LIBAVUTIL_VERSION_INT, + * }; + * + * void *child_next(void *obj, void *prev) + * { + * test_struct *t = obj; + * if (!prev && t->child_struct) + * return t->child_struct; + * return NULL + * } + * const AVClass child_class_next(const AVClass *prev) + * { + * return prev ? NULL : &child_class; + * } + * @endcode + * Putting child_next() and child_class_next() as defined above into + * test_class will now make child_struct's options accessible through + * test_struct (again, proper setup as described above needs to be done on + * child_struct right after it is created). + * + * From the above example it might not be clear why both child_next() + * and child_class_next() are needed. The distinction is that child_next() + * iterates over actually existing objects, while child_class_next() + * iterates over all possible child classes. E.g. if an AVCodecContext + * was initialized to use a codec which has private options, then its + * child_next() will return AVCodecContext.priv_data and finish + * iterating. OTOH child_class_next() on AVCodecContext.av_class will + * iterate over all available codecs with private options. + * + * @subsection avoptions_implement_named_constants Named constants + * It is possible to create named constants for options. Simply set the unit + * field of the option the constants should apply to a string and + * create the constants themselves as options of type AV_OPT_TYPE_CONST + * with their unit field set to the same string. + * Their default_val field should contain the value of the named + * constant. + * For example, to add some named constants for the test_flags option + * above, put the following into the child_opts array: + * @code + * { "test_flags", "This is a test option of flags type.", + * offsetof(child_struct, flags_opt), AV_OPT_TYPE_FLAGS, { .i64 = 0 }, INT_MIN, INT_MAX, "test_unit" }, + * { "flag1", "This is a flag with value 16", 0, AV_OPT_TYPE_CONST, { .i64 = 16 }, 0, 0, "test_unit" }, + * @endcode + * + * @section avoptions_use Using AVOptions + * This section deals with accessing options in an AVOptions-enabled struct. + * Such structs in FFmpeg are e.g. AVCodecContext in libavcodec or + * AVFormatContext in libavformat. + * + * @subsection avoptions_use_examine Examining AVOptions + * The basic functions for examining options are av_opt_next(), which iterates + * over all options defined for one object, and av_opt_find(), which searches + * for an option with the given name. + * + * The situation is more complicated with nesting. An AVOptions-enabled struct + * may have AVOptions-enabled children. Passing the AV_OPT_SEARCH_CHILDREN flag + * to av_opt_find() will make the function search children recursively. + * + * For enumerating there are basically two cases. The first is when you want to + * get all options that may potentially exist on the struct and its children + * (e.g. when constructing documentation). In that case you should call + * av_opt_child_class_next() recursively on the parent struct's AVClass. The + * second case is when you have an already initialized struct with all its + * children and you want to get all options that can be actually written or read + * from it. In that case you should call av_opt_child_next() recursively (and + * av_opt_next() on each result). + * + * @subsection avoptions_use_get_set Reading and writing AVOptions + * When setting options, you often have a string read directly from the + * user. In such a case, simply passing it to av_opt_set() is enough. For + * non-string type options, av_opt_set() will parse the string according to the + * option type. + * + * Similarly av_opt_get() will read any option type and convert it to a string + * which will be returned. Do not forget that the string is allocated, so you + * have to free it with av_free(). + * + * In some cases it may be more convenient to put all options into an + * AVDictionary and call av_opt_set_dict() on it. A specific case of this + * are the format/codec open functions in lavf/lavc which take a dictionary + * filled with option as a parameter. This makes it possible to set some options + * that cannot be set otherwise, since e.g. the input file format is not known + * before the file is actually opened. + */ + +enum AVOptionType{ + AV_OPT_TYPE_FLAGS, + AV_OPT_TYPE_INT, + AV_OPT_TYPE_INT64, + AV_OPT_TYPE_DOUBLE, + AV_OPT_TYPE_FLOAT, + AV_OPT_TYPE_STRING, + AV_OPT_TYPE_RATIONAL, + AV_OPT_TYPE_BINARY, ///< offset must point to a pointer immediately followed by an int for the length + AV_OPT_TYPE_DICT, + AV_OPT_TYPE_UINT64, + AV_OPT_TYPE_CONST, + AV_OPT_TYPE_IMAGE_SIZE, ///< offset must point to two consecutive integers + AV_OPT_TYPE_PIXEL_FMT, + AV_OPT_TYPE_SAMPLE_FMT, + AV_OPT_TYPE_VIDEO_RATE, ///< offset must point to AVRational + AV_OPT_TYPE_DURATION, + AV_OPT_TYPE_COLOR, + AV_OPT_TYPE_CHANNEL_LAYOUT, + AV_OPT_TYPE_BOOL, +}; + +/** + * AVOption + */ +typedef struct AVOption { + const char *name; + + /** + * short English help text + * @todo What about other languages? + */ + const char *help; + + /** + * The offset relative to the context structure where the option + * value is stored.

(Some other Free Software Foundation software is covered by\n" +"the GNU Lesser General Public License instead.) You can apply it to\n" +"your programs, too.\n" +"\n" +" When we speak of free software, we are referring to freedom, not\n" +"price. Our General Public Licenses are designed to make sure that you\n" +"have the freedom to distribute copies of free software (and charge for\n" +"this service if you wish), that you receive source code or can get it\n" +"if you want it, that you can change the software or use pieces of it\n" +"in new free programs; and that you know you can do these things.\n" +"\n" +" To protect your rights, we need to make restrictions that forbid\n" +"anyone to deny you these rights or to ask you to surrender the rights.\n" +"These restrictions translate to certain responsibilities for you if you\n" +"distribute copies of the software, or if you modify it.\n" +"\n" +" For example, if you distribute copies of such a program, whether\n" +"gratis or for a fee, you must give the recipients all the rights that\n" +"you have.

We wish to avoid the danger that redistributors of a free\n" +"program will individually obtain patent licenses, in effect making the\n" +"program proprietary. To prevent this, we have made it clear that any\n" +"patent must be licensed for everyone's free use or not licensed at all.\n" +"\n" +" The precise terms and conditions for copying, distribution and\n" +"modification follow.\n" +"\n" +" GNU GENERAL PUBLIC LICENSE\n" +" TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION\n" +"\n" +" 0. This License applies to any program or other work which contains\n" +"a notice placed by the copyright holder saying it may be distributed\n" +"under the terms of this General Public License. The \"Program\", below,\n" +"refers to any such program or work, and a \"work based on the Program\"\n" +"means either the Program or any derivative work under copyright law:\n" +"that is to say, a work containing the Program or a portion of it,\n" +"either verbatim or with modifications and/or translated into another\n" +"language. (Hereinafter, translation is included without limitation in\n" +"the term \"modification\".) Each licensee is addressed as \"you\".\n" +"\n" +"Activities other than copying, distribution and modification are not\n" +"covered by this License; they are outside its scope. The act of\n" +"running the Program is not restricted, and the output from the Program\n" +"is covered only if its contents constitute a work based on the\n" +"Program (independent of having been made by running the Program).\n" +"Whether that is true depends on what the Program does.\n" +"\n" +" 1. You may copy and distribute verbatim copies of the Program's\n" +"source code as you receive it, in any medium, provided that you\n" +"conspicuously and appropriately publish on each copy an appropriate\n" +"copyright notice and disclaimer of warranty; keep intact all the\n" +"notices that refer to this License and to the absence of any warranty;\n" +"and give any other recipients of the Program a copy of this License\n" +"along with the Program.\n" +"\n" +"You may charge a fee for the physical act of transferring a copy, and\n" +"you may at your option offer warranty protection in exchange for a fee.\n" +"\n" +" 2. You may modify your copy or copies of the Program or any portion\n" +"of it, thus forming a work based on the Program, and copy and\n" +"distribute such modifications or work under the terms of Section 1\n" +"above, provided that you also meet all of these conditions:\n" +"\n" +" a) You must cause the modified files to carry prominent notices\n" +" stating that you changed the files and the date of any change.\n" +"\n" +" b) You must cause any work that you distribute or publish, that in\n" +" whole or in part contains or is derived from the Program or any\n" +" part thereof, to be licensed as a whole at no charge to all third\n" +" parties under the terms of this License.\n" +"\n" +" c) If the modified program normally reads commands interactively\n" +" when run, you must cause it, when started running for such\n" +" interactive use in the most ordinary way, to print or display an\n" +" announcement including an appropriate copyright notice and a\n" +" notice that there is no warranty (or else, saying that you provide\n" +" a warranty) and that users may redistribute the program under\n" +" these conditions, and telling the user how to view a copy of this\n" +" License. (Exception: if the Program itself is interactive but\n" +" does not normally print such an announcement, your work based on\n" +" the Program is not required to print an announcement.)\n" +"\n" +"These requirements apply to the modified work as a whole. If\n" +"identifiable sections of that work are not derived from the Program,\n" +"and can be reasonably considered independent and separate works in\n" +"themselves, then this License, and its terms, do not apply to those\n" +"sections when you distribute them as separate works. But when you\n" +"distribute the same sections as part of a whole which is a work based\n" +"on the Program, the distribution of the whole must be on the terms of\n" +"this License, whose permissions for other licensees extend to the\n" +"entire whole, and thus to each and every part regardless of who wrote it.\n" +"\n" +"Thus, it is not the intent of this section to claim rights or contest\n" +"your rights to work written entirely by you; rather, the intent is to\n" +"exercise the right to control the distribution of derivative or\n" +"collective works based on the Program.\n" +"\n" +"In addition, mere aggregation of another work not based on the Program\n" +"with the Program (or with a work based on the Program) on a volume of\n" +"a storage or distribution medium does not bring the other work under\n" +"the scope of this License.\n" +"\n" +" 3. You may copy and distribute the Program (or a work based on it,\n" +"under Section 2) in object code or executable form under the terms of\n" +"Sections 1 and 2 above provided that you also do one of the following:\n" +"\n" +" a) Accompany it with the complete corresponding machine-readable\n" +" source code, which must be distributed under the terms of Sections\n" +" 1 and 2 above on a medium customarily used for software interchange; or,\n" +"\n" +" b) Accompany it with a written offer, valid for at least three\n" +" years, to give any third party, for a charge no more than your\n" +" cost of physically performing source distribution, a complete\n" +" machine-readable copy of the corresponding source code, to be\n" +" distributed under the terms of Sections 1 and 2 above on a medium\n" +" customarily used for software interchange; or,\n" +"\n" +" c) Accompany it with the information you received as to the offer\n" +" to distribute corresponding source code. (This alternative is\n" +" allowed only for noncommercial distribution and only if you\n" +" received the program in object code or executable form with such\n" +" an offer, in accord with Subsection b above.)\n" +"\n" +"The source code for a work means the preferred form of the work for\n" +"making modifications to it. For an executable work, complete source\n" +"code means all the source code for all modules it contains, plus any\n" +"associated interface definition files, plus the scripts used to\n" +"control compilation and installation of the executable. However, as a\n" +"special exception, the source code distributed need not include\n" +"anything that is normally distributed (in either source or binary\n" +"form) with the major components (compiler, kernel, and so on) of the\n" +"operating system on which the executable runs, unless that component\n" +"itself accompanies the executable.\n" +"\n" +"If distribution of executable or object code is made by offering\n" +"access to copy from a designated place, then offering equivalent\n" +"access to copy the source code from the same place counts as\n" +"distribution of the source code, even though third parties are not\n" +"compelled to copy the source along with the object code.\n" +"\n" +" 4. You may not copy, modify, sublicense, or distribute the Program\n" +"except as expressly provided under this License. Any attempt\n" +"otherwise to copy, modify, sublicense or distribute the Program is\n" +"void, and will automatically terminate your rights under this License.\n" +"However, parties who have received copies, or rights, from you under\n" +"this License will not have their licenses terminated so long as such\n" +"parties remain in full compliance.\n" +"\n" +" 5. You are not required to accept this License, since you have not\n" +"signed it. However, nothing else grants you permission to modify or\n" +"distribute the Program or its derivative works. These actions are\n" +"prohibited by law if you do not accept this License. Therefore, by\n" +"modifying or distributing the Program (or any work based on the\n" +"Program), you indicate your acceptance of this License to do so, and\n" +"all its terms and conditions for copying, distributing or modifying\n" +"the Program or works based on it.\n" +"\n" +" 6. Each time you redistribute the Program (or any work based on the\n" +"Program), the recipient automatically receives a license from the\n" +"original licensor to copy, distribute or modify the Program subject to\n" +"these terms and conditions. You may not impose any further\n" +"restrictions on the recipients' exercise of the rights granted herein.\n" +"You are not responsible for enforcing compliance by third parties to\n" +"this License.\n" +"\n" +" 7. If, as a consequence of a court judgment or allegation of patent\n" +"infringement or for any other reason (not limited to patent issues),\n" +"conditions are imposed on you (whether by court order, agreement or\n" +"otherwise) that contradict the conditions of this License, they do not\n" +"excuse you from the conditions of this License. If you cannot\n" +"distribute so as to satisfy simultaneously your obligations under this\n" +"License and any other pertinent obligations, then as a consequence you\n" +"may not distribute the Program at all. For example, if a patent\n" +"license would not permit royalty-free redistribution of the Program by\n" +"all those who receive copies directly or indirectly through you, then\n" +"the only way you could satisfy both it and this License would be to\n" +"refrain entirely from distribution of the Program.\n" +"\n" +"If any portion of this section is held invalid or unenforceable under\n" +"any particular circumstance, the balance of the section is intended to\n" +"apply and the section as a whole is intended to apply in other\n" +"circumstances.\n" +"\n" +"It is not the purpose of this section to induce you to infringe any\n" +"patents or other property right claims or to contest validity of any\n" +"such claims; this section has the sole purpose of protecting the\n" +"integrity of the free software distribution system, which is\n" +"implemented by public license practices. Many people have made\n" +"generous contributions to the wide range of software distributed\n" +"through that system in reliance on consistent application of that\n" +"system; it is up to the author/donor to decide if he or she is willing\n" +"to distribute software through any other system and a licensee cannot\n" +"impose that choice.\n" +"\n" +"This section is intended to make thoroughly clear what is believed to\n" +"be a consequence of the rest of this License.\n" +"\n" +" 8. If the distribution and/or use of the Program is restricted in\n" +"certain countries either by patents or by copyrighted interfaces, the\n" +"original copyright holder who places the Program under this License\n" +"may add an explicit geographical distribution limitation excluding\n" +"those countries, so that distribution is permitted only in or among\n" +"countries not thus excluded. In such case, this License incorporates\n" +"the limitation as if written in the body of this License.\n" +"\n" +" 9. The Free Software Foundation may publish revised and/or new versions\n" +"of the General Public License from time to time. Such new versions will\n" +"be similar in spirit to the present version, but may differ in detail to\n" +"address new problems or concerns.\n" +"\n" +"Each version is given a distinguishing version number. If the Program\n" +"specifies a version number of this License which applies to it and \"any\n" +"later version\", you have the option of following the terms and conditions\n" +"either of that version or of any later version published by the Free\n" +"Software Foundation. If the Program does not specify a version number of\n" +"this License, you may choose any version ever published by the Free Software\n" +"Foundation.\n" +"\n" +" 10.

This allows advanced + * categorization, like for SAP streams (which are grouped by "sap groups"). + * + * The base structure for all playlist operations is the input_item_t. This + * contains all information needed to play a stream and get info, ie, mostly, + * mrl and metadata. This structure contains a unique i_id field. ids are + * not recycled when an item is destroyed. + * + * Input items are not used directly, but through playlist items. + * The playlist items are themselves in a tree structure. They only contain + * a link to the input item, a unique id and a few flags. the playlist + * item id is NOT the same as the input item id. + * Several playlist items can be attached to a single input item. The input + * item is refcounted and is automatically destroyed when it is not used + * anymore. + * + * The top-level items are the main media sources and include: + * playlist, media library, SAP, Shoutcast, devices, ... + * + * It is envisioned that a third tree will appear: VLM, but it's not done yet + * + * The playlist also stores, for utility purposes, an array of all input + * items, an array of all playlist items and an array of all playlist items + * and nodes (both are represented by the same structure). + * + * So, here is an example: + * \verbatim + * Inputs array + * - input 1 -> name = foo 1 uri = ... + * - input 2 -> name = foo 2 uri = ... + * + * Playlist items tree + * - playlist (id 1) + * - category 1 (id 2) + * - foo 2 (id 6 - input 2) + * - media library (id 2) + * - foo 1 (id 5 - input 1) + * \endverbatim + * + * Sometimes, an item creates subitems. This happens for the directory access + * for example. In that case, if the item is under the "playlist" top-level item + * and playlist is configured to be flat then the item will be deleted and + * replaced with new subitems. If the item is under another top-level item, it + * will be transformed to a node and removed from the list of all items without + * nodes. + * + * For "standard" item addition, you can use playlist_Add, playlist_AddExt + * (more options) or playlist_AddInput if you already created your input + * item. This will add the item at the root of "Playlist" or of "Media library" + * in each of the two trees. + * + * You can create nodes with playlist_NodeCreate and can create items from + * existing input items to be placed under any node with playlist_NodeAddInput. + * + * To delete an item, use playlist_DeleteFromInput( p_item ) which will + * remove all occurrences of the input. + * + * + * The playlist defines the following event variables: + * + * - "item-change": It will contain the input_item_t->i_id of a changed input + * item monitored by the playlist. + * item being played. + * + * - "playlist-item-append": It will contain a pointer to a playlist_add_t. + * - "playlist-item-deleted": It will contain the playlist_item_t->i_id of a + * deleted playlist_item_t. + * + * - "leaf-to-parent": It will contain the playlist_item_t->i_id of an item that is transformed + * into a node. + * + * The playlist contains rate-variable which is propagated to current input if available + * also rate-slower/rate-faster is in use + * + * XXX Be really carefull, playlist_item_t->i_id and input_item_t->i_id are not + * the same.

But when you\n" +"distribute the same sections as part of a whole which is a work based\n" +"on the Program, the distribution of the whole must be on the terms of\n" +"this License, whose permissions for other licensees extend to the\n" +"entire whole, and thus to each and every part regardless of who wrote it.\n" +"\n" +"Thus, it is not the intent of this section to claim rights or contest\n" +"your rights to work written entirely by you; rather, the intent is to\n" +"exercise the right to control the distribution of derivative or\n" +"collective works based on the Program.\n" +"\n" +"In addition, mere aggregation of another work not based on the Program\n" +"with the Program (or with a work based on the Program) on a volume of\n" +"a storage or distribution medium does not bring the other work under\n" +"the scope of this License.\n" +"\n" +" 3. You may copy and distribute the Program (or a work based on it,\n" +"under Section 2) in object code or executable form under the terms of\n" +"Sections 1 and 2 above provided that you also do one of the following:\n" +"\n" +" a) Accompany it with the complete corresponding machine-readable\n" +" source code, which must be distributed under the terms of Sections\n" +" 1 and 2 above on a medium customarily used for software interchange; or,\n" +"\n" +" b) Accompany it with a written offer, valid for at least three\n" +" years, to give any third party, for a charge no more than your\n" +" cost of physically performing source distribution, a complete\n" +" machine-readable copy of the corresponding source code, to be\n" +" distributed under the terms of Sections 1 and 2 above on a medium\n" +" customarily used for software interchange; or,\n" +"\n" +" c) Accompany it with the information you received as to the offer\n" +" to distribute corresponding source code. (This alternative is\n" +" allowed only for noncommercial distribution and only if you\n" +" received the program in object code or executable form with such\n" +" an offer, in accord with Subsection b above.)\n" +"\n" +"The source code for a work means the preferred form of the work for\n" +"making modifications to it. For an executable work, complete source\n" +"code means all the source code for all modules it contains, plus any\n" +"associated interface definition files, plus the scripts used to\n" +"control compilation and installation of the executable. However, as a\n" +"special exception, the source code distributed need not include\n" +"anything that is normally distributed (in either source or binary\n" +"form) with the major components (compiler, kernel, and so on) of the\n" +"operating system on which the executable runs, unless that component\n" +"itself accompanies the executable.\n" +"\n" +"If distribution of executable or object code is made by offering\n" +"access to copy from a designated place, then offering equivalent\n" +"access to copy the source code from the same place counts as\n" +"distribution of the source code, even though third parties are not\n" +"compelled to copy the source along with the object code.\n" +"\n" +" 4. You may not copy, modify, sublicense, or distribute the Program\n" +"except as expressly provided under this License. Any attempt\n" +"otherwise to copy, modify, sublicense or distribute the Program is\n" +"void, and will automatically terminate your rights under this License.\n" +"However, parties who have received copies, or rights, from you under\n" +"this License will not have their licenses terminated so long as such\n" +"parties remain in full compliance.\n" +"\n" +" 5. You are not required to accept this License, since you have not\n" +"signed it. However, nothing else grants you permission to modify or\n" +"distribute the Program or its derivative works. These actions are\n" +"prohibited by law if you do not accept this License. Therefore, by\n" +"modifying or distributing the Program (or any work based on the\n" +"Program), you indicate your acceptance of this License to do so, and\n" +"all its terms and conditions for copying, distributing or modifying\n" +"the Program or works based on it.\n" +"\n" +" 6. Each time you redistribute the Program (or any work based on the\n" +"Program), the recipient automatically receives a license from the\n" +"original licensor to copy, distribute or modify the Program subject to\n" +"these terms and conditions. You may not impose any further\n" +"restrictions on the recipients' exercise of the rights granted herein.\n" +"You are not responsible for enforcing compliance by third parties to\n" +"this License.\n" +"\n" +" 7. If, as a consequence of a court judgment or allegation of patent\n" +"infringement or for any other reason (not limited to patent issues),\n" +"conditions are imposed on you (whether by court order, agreement or\n" +"otherwise) that contradict the conditions of this License, they do not\n" +"excuse you from the conditions of this License. If you cannot\n" +"distribute so as to satisfy simultaneously your obligations under this\n" +"License and any other pertinent obligations, then as a consequence you\n" +"may not distribute the Program at all. For example, if a patent\n" +"license would not permit royalty-free redistribution of the Program by\n" +"all those who receive copies directly or indirectly through you, then\n" +"the only way you could satisfy both it and this License would be to\n" +"refrain entirely from distribution of the Program.\n" +"\n" +"If any portion of this section is held invalid or unenforceable under\n" +"any particular circumstance, the balance of the section is intended to\n" +"apply and the section as a whole is intended to apply in other\n" +"circumstances.\n" +"\n" +"It is not the purpose of this section to induce you to infringe any\n" +"patents or other property right claims or to contest validity of any\n" +"such claims; this section has the sole purpose of protecting the\n" +"integrity of the free software distribution system, which is\n" +"implemented by public license practices. Many people have made\n" +"generous contributions to the wide range of software distributed\n" +"through that system in reliance on consistent application of that\n" +"system; it is up to the author/donor to decide if he or she is willing\n" +"to distribute software through any other system and a licensee cannot\n" +"impose that choice.\n" +"\n" +"This section is intended to make thoroughly clear what is believed to\n" +"be a consequence of the rest of this License.\n" +"\n" +" 8. If the distribution and/or use of the Program is restricted in\n" +"certain countries either by patents or by copyrighted interfaces, the\n" +"original copyright holder who places the Program under this License\n" +"may add an explicit geographical distribution limitation excluding\n" +"those countries, so that distribution is permitted only in or among\n" +"countries not thus excluded. In such case, this License incorporates\n" +"the limitation as if written in the body of this License.\n" +"\n" +" 9. The Free Software Foundation may publish revised and/or new versions\n" +"of the General Public License from time to time. Such new versions will\n" +"be similar in spirit to the present version, but may differ in detail to\n" +"address new problems or concerns.\n" +"\n" +"Each version is given a distinguishing version number. If the Program\n" +"specifies a version number of this License which applies to it and \"any\n" +"later version\", you have the option of following the terms and conditions\n" +"either of that version or of any later version published by the Free\n" +"Software Foundation. If the Program does not specify a version number of\n" +"this License, you may choose any version ever published by the Free Software\n" +"Foundation.\n" +"\n" +" 10. If you wish to incorporate parts of the Program into other free\n" +"programs whose distribution conditions are different, write to the author\n" +"to ask for permission. For software which is copyrighted by the Free\n" +"Software Foundation, write to the Free Software Foundation; we sometimes\n" +"make exceptions for this. Our decision will be guided by the two goals\n" +"of preserving the free status of all derivatives of our free software and\n" +"of promoting the sharing and reuse of software generally.\n" +"\n" +" NO WARRANTY\n" +"\n" +" 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY\n" +"FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN\n" +"OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES\n" +"PROVIDE THE PROGRAM \"AS IS\" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED\n" +"OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF\n" +"MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS\n" +"TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE\n" +"PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,\n" +"REPAIR OR CORRECTION.\n" +"\n" +" 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING\n" +"WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR\n" +"REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,\n" +"INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING\n" +"OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED\n" +"TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY\n" +"YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER\n" +"PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE\n" +"POSSIBILITY OF SUCH DAMAGES.\n" +"\n" +" END OF TERMS AND CONDITIONS\n" +"\n" +" How to Apply These Terms to Your New Programs\n" +"\n" +" If you develop a new program, and you want it to be of the greatest\n" +"possible use to the public, the best way to achieve this is to make it\n" +"free software which everyone can redistribute and change under these terms.\n" +"\n" +" To do so, attach the following notices to the program. It is safest\n" +"to attach them to the start of each source file to most effectively\n" +"convey the exclusion of warranty; and each file should have at least\n" +"the \"copyright\" line and a pointer to where the full notice is found.\n" +"\n" +" \n" +" Copyright (C) \n" +"\n" +" This program is free software; you can redistribute it and/or modify\n" +" it under the terms of the GNU General Public License as published by\n" +" the Free Software Foundation; either version 2 of the License, or\n" +" (at your option) any later version.\n" +"\n" +" This program is distributed in the hope that it will be useful,\n" +" but WITHOUT ANY WARRANTY; without even the implied warranty of\n" +" MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

This allows advanced + * categorization, like for SAP streams (which are grouped by "sap groups"). + * + * The base structure for all playlist operations is the input_item_t. This + * contains all information needed to play a stream and get info, ie, mostly, + * mrl and metadata. This structure contains a unique i_id field. ids are + * not recycled when an item is destroyed. + * + * Input items are not used directly, but through playlist items. + * The playlist items are themselves in a tree structure. They only contain + * a link to the input item, a unique id and a few flags. the playlist + * item id is NOT the same as the input item id. + * Several playlist items can be attached to a single input item. The input + * item is refcounted and is automatically destroyed when it is not used + * anymore. + * + * The top-level items are the main media sources and include: + * playlist, media library, SAP, Shoutcast, devices, ... + * + * It is envisioned that a third tree will appear: VLM, but it's not done yet + * + * The playlist also stores, for utility purposes, an array of all input + * items, an array of all playlist items and an array of all playlist items + * and nodes (both are represented by the same structure). + * + * So, here is an example: + * \verbatim + * Inputs array + * - input 1 -> name = foo 1 uri = ... + * - input 2 -> name = foo 2 uri = ... + * + * Playlist items tree + * - playlist (id 1) + * - category 1 (id 2) + * - foo 2 (id 6 - input 2) + * - media library (id 2) + * - foo 1 (id 5 - input 1) + * \endverbatim + * + * Sometimes, an item creates subitems. This happens for the directory access + * for example. In that case, if the item is under the "playlist" top-level item + * and playlist is configured to be flat then the item will be deleted and + * replaced with new subitems. If the item is under another top-level item, it + * will be transformed to a node and removed from the list of all items without + * nodes. + * + * For "standard" item addition, you can use playlist_Add, playlist_AddExt + * (more options) or playlist_AddInput if you already created your input + * item. This will add the item at the root of "Playlist" or of "Media library" + * in each of the two trees. + * + * You can create nodes with playlist_NodeCreate and can create items from + * existing input items to be placed under any node with playlist_NodeAddInput. + * + * To delete an item, use playlist_DeleteFromInput( p_item ) which will + * remove all occurrences of the input. + * + * + * The playlist defines the following event variables: + * + * - "item-change": It will contain the input_item_t->i_id of a changed input + * item monitored by the playlist. + * item being played. + * + * - "playlist-item-append": It will contain a pointer to a playlist_add_t. + * - "playlist-item-deleted": It will contain the playlist_item_t->i_id of a + * deleted playlist_item_t. + * + * - "leaf-to-parent": It will contain the playlist_item_t->i_id of an item that is transformed + * into a node. + * + * The playlist contains rate-variable which is propagated to current input if available + * also rate-slower/rate-faster is in use + * + * XXX Be really carefull, playlist_item_t->i_id and input_item_t->i_id are not + * the same.

This\n" +"General Public License applies to most of the Free Software\n" +"Foundation's software and to any other program whose authors commit to\n" +"using it. (Some other Free Software Foundation software is covered by\n" +"the GNU Lesser General Public License instead.) You can apply it to\n" +"your programs, too.\n" +"\n" +" When we speak of free software, we are referring to freedom, not\n" +"price. Our General Public Licenses are designed to make sure that you\n" +"have the freedom to distribute copies of free software (and charge for\n" +"this service if you wish), that you receive source code or can get it\n" +"if you want it, that you can change the software or use pieces of it\n" +"in new free programs; and that you know you can do these things.\n" +"\n" +" To protect your rights, we need to make restrictions that forbid\n" +"anyone to deny you these rights or to ask you to surrender the rights.\n" +"These restrictions translate to certain responsibilities for you if you\n" +"distribute copies of the software, or if you modify it.\n" +"\n" +" For example, if you distribute copies of such a program, whether\n" +"gratis or for a fee, you must give the recipients all the rights that\n" +"you have. You must make sure that they, too, receive or can get the\n" +"source code. And you must show them these terms so they know their\n" +"rights.\n" +"\n" +" We protect your rights with two steps: (1) copyright the software, and\n" +"(2) offer you this license which gives you legal permission to copy,\n" +"distribute and/or modify the software.\n" +"\n" +" Also, for each author's protection and ours, we want to make certain\n" +"that everyone understands that there is no warranty for this free\n" +"software. If the software is modified by someone else and passed on, we\n" +"want its recipients to know that what they have is not the original, so\n" +"that any problems introduced by others will not reflect on the original\n" +"authors' reputations.\n" +"\n" +" Finally, any free program is threatened constantly by software\n" +"patents. We wish to avoid the danger that redistributors of a free\n" +"program will individually obtain patent licenses, in effect making the\n" +"program proprietary. To prevent this, we have made it clear that any\n" +"patent must be licensed for everyone's free use or not licensed at all.\n" +"\n" +" The precise terms and conditions for copying, distribution and\n" +"modification follow.\n" +"\n" +" GNU GENERAL PUBLIC LICENSE\n" +" TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION\n" +"\n" +" 0. This License applies to any program or other work which contains\n" +"a notice placed by the copyright holder saying it may be distributed\n" +"under the terms of this General Public License. The \"Program\", below,\n" +"refers to any such program or work, and a \"work based on the Program\"\n" +"means either the Program or any derivative work under copyright law:\n" +"that is to say, a work containing the Program or a portion of it,\n" +"either verbatim or with modifications and/or translated into another\n" +"language. (Hereinafter, translation is included without limitation in\n" +"the term \"modification\".) Each licensee is addressed as \"you\".\n" +"\n" +"Activities other than copying, distribution and modification are not\n" +"covered by this License; they are outside its scope. The act of\n" +"running the Program is not restricted, and the output from the Program\n" +"is covered only if its contents constitute a work based on the\n" +"Program (independent of having been made by running the Program).\n" +"Whether that is true depends on what the Program does.\n" +"\n" +" 1. You may copy and distribute verbatim copies of the Program's\n" +"source code as you receive it, in any medium, provided that you\n" +"conspicuously and appropriately publish on each copy an appropriate\n" +"copyright notice and disclaimer of warranty; keep intact all the\n" +"notices that refer to this License and to the absence of any warranty;\n" +"and give any other recipients of the Program a copy of this License\n" +"along with the Program.\n" +"\n" +"You may charge a fee for the physical act of transferring a copy, and\n" +"you may at your option offer warranty protection in exchange for a fee.\n" +"\n" +" 2. You may modify your copy or copies of the Program or any portion\n" +"of it, thus forming a work based on the Program, and copy and\n" +"distribute such modifications or work under the terms of Section 1\n" +"above, provided that you also meet all of these conditions:\n" +"\n" +" a) You must cause the modified files to carry prominent notices\n" +" stating that you changed the files and the date of any change.\n" +"\n" +" b) You must cause any work that you distribute or publish, that in\n" +" whole or in part contains or is derived from the Program or any\n" +" part thereof, to be licensed as a whole at no charge to all third\n" +" parties under the terms of this License.\n" +"\n" +" c) If the modified program normally reads commands interactively\n" +" when run, you must cause it, when started running for such\n" +" interactive use in the most ordinary way, to print or display an\n" +" announcement including an appropriate copyright notice and a\n" +" notice that there is no warranty (or else, saying that you provide\n" +" a warranty) and that users may redistribute the program under\n" +" these conditions, and telling the user how to view a copy of this\n" +" License. (Exception: if the Program itself is interactive but\n" +" does not normally print such an announcement, your work based on\n" +" the Program is not required to print an announcement.)\n" +"\n" +"These requirements apply to the modified work as a whole. If\n" +"identifiable sections of that work are not derived from the Program,\n" +"and can be reasonably considered independent and separate works in\n" +"themselves, then this License, and its terms, do not apply to those\n" +"sections when you distribute them as separate works. But when you\n" +"distribute the same sections as part of a whole which is a work based\n" +"on the Program, the distribution of the whole must be on the terms of\n" +"this License, whose permissions for other licensees extend to the\n" +"entire whole, and thus to each and every part regardless of who wrote it.\n" +"\n" +"Thus, it is not the intent of this section to claim rights or contest\n" +"your rights to work written entirely by you; rather, the intent is to\n" +"exercise the right to control the distribution of derivative or\n" +"collective works based on the Program.\n" +"\n" +"In addition, mere aggregation of another work not based on the Program\n" +"with the Program (or with a work based on the Program) on a volume of\n" +"a storage or distribution medium does not bring the other work under\n" +"the scope of this License.\n" +"\n" +" 3. You may copy and distribute the Program (or a work based on it,\n" +"under Section 2) in object code or executable form under the terms of\n" +"Sections 1 and 2 above provided that you also do one of the following:\n" +"\n" +" a) Accompany it with the complete corresponding machine-readable\n" +" source code, which must be distributed under the terms of Sections\n" +" 1 and 2 above on a medium customarily used for software interchange; or,\n" +"\n" +" b) Accompany it with a written offer, valid for at least three\n" +" years, to give any third party, for a charge no more than your\n" +" cost of physically performing source distribution, a complete\n" +" machine-readable copy of the corresponding source code, to be\n" +" distributed under the terms of Sections 1 and 2 above on a medium\n" +" customarily used for software interchange; or,\n" +"\n" +" c) Accompany it with the information you received as to the offer\n" +" to distribute corresponding source code. (This alternative is\n" +" allowed only for noncommercial distribution and only if you\n" +" received the program in object code or executable form with such\n" +" an offer, in accord with Subsection b above.)\n" +"\n" +"The source code for a work means the preferred form of the work for\n" +"making modifications to it. For an executable work, complete source\n" +"code means all the source code for all modules it contains, plus any\n" +"associated interface definition files, plus the scripts used to\n" +"control compilation and installation of the executable. However, as a\n" +"special exception, the source code distributed need not include\n" +"anything that is normally distributed (in either source or binary\n" +"form) with the major components (compiler, kernel, and so on) of the\n" +"operating system on which the executable runs, unless that component\n" +"itself accompanies the executable.\n" +"\n" +"If distribution of executable or object code is made by offering\n" +"access to copy from a designated place, then offering equivalent\n" +"access to copy the source code from the same place counts as\n" +"distribution of the source code, even though third parties are not\n" +"compelled to copy the source along with the object code.\n" +"\n" +" 4. You may not copy, modify, sublicense, or distribute the Program\n" +"except as expressly provided under this License. Any attempt\n" +"otherwise to copy, modify, sublicense or distribute the Program is\n" +"void, and will automatically terminate your rights under this License.\n" +"However, parties who have received copies, or rights, from you under\n" +"this License will not have their licenses terminated so long as such\n" +"parties remain in full compliance.\n" +"\n" +" 5. You are not required to accept this License, since you have not\n" +"signed it. However, nothing else grants you permission to modify or\n" +"distribute the Program or its derivative works. These actions are\n" +"prohibited by law if you do not accept this License. Therefore, by\n" +"modifying or distributing the Program (or any work based on the\n" +"Program), you indicate your acceptance of this License to do so, and\n" +"all its terms and conditions for copying, distributing or modifying\n" +"the Program or works based on it.\n" +"\n" +" 6. Each time you redistribute the Program (or any work based on the\n" +"Program), the recipient automatically receives a license from the\n" +"original licensor to copy, distribute or modify the Program subject to\n" +"these terms and conditions. You may not impose any further\n" +"restrictions on the recipients' exercise of the rights granted herein.\n" +"You are not responsible for enforcing compliance by third parties to\n" +"this License.\n" +"\n" +" 7. If, as a consequence of a court judgment or allegation of patent\n" +"infringement or for any other reason (not limited to patent issues),\n" +"conditions are imposed on you (whether by court order, agreement or\n" +"otherwise) that contradict the conditions of this License, they do not\n" +"excuse you from the conditions of this License. If you cannot\n" +"distribute so as to satisfy simultaneously your obligations under this\n" +"License and any other pertinent obligations, then as a consequence you\n" +"may not distribute the Program at all. For example, if a patent\n" +"license would not permit royalty-free redistribution of the Program by\n" +"all those who receive copies directly or indirectly through you, then\n" +"the only way you could satisfy both it and this License would be to\n" +"refrain entirely from distribution of the Program.\n" +"\n" +"If any portion of this section is held invalid or unenforceable under\n" +"any particular circumstance, the balance of the section is intended to\n" +"apply and the section as a whole is intended to apply in other\n" +"circumstances.\n" +"\n" +"It is not the purpose of this section to induce you to infringe any\n" +"patents or other property right claims or to contest validity of any\n" +"such claims; this section has the sole purpose of protecting the\n" +"integrity of the free software distribution system, which is\n" +"implemented by public license practices. Many people have made\n" +"generous contributions to the wide range of software distributed\n" +"through that system in reliance on consistent application of that\n" +"system; it is up to the author/donor to decide if he or she is willing\n" +"to distribute software through any other system and a licensee cannot\n" +"impose that choice.\n" +"\n" +"This section is intended to make thoroughly clear what is believed to\n" +"be a consequence of the rest of this License.\n" +"\n" +" 8. If the distribution and/or use of the Program is restricted in\n" +"certain countries either by patents or by copyrighted interfaces, the\n" +"original copyright holder who places the Program under this License\n" +"may add an explicit geographical distribution limitation excluding\n" +"those countries, so that distribution is permitted only in or among\n" +"countries not thus excluded. In such case, this License incorporates\n" +"the limitation as if written in the body of this License.\n" +"\n" +" 9. The Free Software Foundation may publish revised and/or new versions\n" +"of the General Public License from time to time. Such new versions will\n" +"be similar in spirit to the present version, but may differ in detail to\n" +"address new problems or concerns.\n" +"\n" +"Each version is given a distinguishing version number. If the Program\n" +"specifies a version number of this License which applies to it and \"any\n" +"later version\", you have the option of following the terms and conditions\n" +"either of that version or of any later version published by the Free\n" +"Software Foundation. If the Program does not specify a version number of\n" +"this License, you may choose any version ever published by the Free Software\n" +"Foundation.\n" +"\n" +" 10. If you wish to incorporate parts of the Program into other free\n" +"programs whose distribution conditions are different, write to the author\n" +"to ask for permission. For software which is copyrighted by the Free\n" +"Software Foundation, write to the Free Software Foundation; we sometimes\n" +"make exceptions for this. Our decision will be guided by the two goals\n" +"of preserving the free status of all derivatives of our free software and\n" +"of promoting the sharing and reuse of software generally.\n" +"\n" +" NO WARRANTY\n" +"\n" +" 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY\n" +"FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN\n" +"OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES\n" +"PROVIDE THE PROGRAM \"AS IS\" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED\n" +"OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF\n" +"MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS\n" +"TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE\n" +"PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,\n" +"REPAIR OR CORRECTION.\n" +"\n" +" 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING\n" +"WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR\n" +"REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,\n" +"INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING\n" +"OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED\n" +"TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY\n" +"YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER\n" +"PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE\n" +"POSSIBILITY OF SUCH DAMAGES.\n" +"\n" +" END OF TERMS AND CONDITIONS\n" +"\n" +" How to Apply These Terms to Your New Programs\n" +"\n" +" If you develop a new program, and you want it to be of the greatest\n" +"possible use to the public, the best way to achieve this is to make it\n" +"free software which everyone can redistribute and change under these terms.\n" +"\n" +" To do so, attach the following notices to the program. It is safest\n" +"to attach them to the start of each source file to most effectively\n" +"convey the exclusion of warranty; and each file should have at least\n" +"the \"copyright\" line and a pointer to where the full notice is found.\n" +"\n" +" \n" +" Copyright (C) \n" +"\n" +" This program is free software; you can redistribute it and/or modify\n" +" it under the terms of the GNU General Public License as published by\n" +" the Free Software Foundation; either version 2 of the License, or\n" +" (at your option) any later version.\n" +"\n" +" This program is distributed in the hope that it will be useful,\n" +" but WITHOUT ANY WARRANTY; without even the implied warranty of\n" +" MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

This allows advanced + * categorization, like for SAP streams (which are grouped by "sap groups"). + * + * The base structure for all playlist operations is the playlist_item_t. + * This is essentially a node within the playlist tree. Each playlist item + * references an input_item_t which contains the input stream info, such as + * location, name and meta-data. + * + * A playlist item is uniquely identified by its input item: + * \ref playlist_ItemGetByInput(). A single input item cannot be used by more + * than one playlist item at a time; if necessary, a copy of the input item can + * be made instead. + * + * The same playlist tree is visible to all user interfaces. To arbitrate + * access, a lock is used, see \ref playlist_Lock() and \ref playlist_Unlock(). + * + * Under the playlist root item node, the top-level items are the main + * media sources and include: + * - the actual playlist, + * - the media library, + * - the service discovery root node, whose children are services discovery + * module instances. + * + * So, here is an example: + * \verbatim + * Inputs array + * - input 1 -> name = foo 1 uri = ... + * - input 2 -> name = foo 2 uri = ... + * + * Playlist items tree + * - playlist (id 1) + * - category 1 (id 2) + * - foo 2 (id 6 - input 2) + * - media library (id 2) + * - foo 1 (id 5 - input 1) + * \endverbatim + * + * Sometimes, an item creates subitems. This happens for the directory access + * for example. In that case, if the item is under the "playlist" top-level + * item and playlist is configured to be flat then the item will be deleted and + * replaced with new subitems. If the item is under another top-level item, it + * will be transformed to a node and removed from the list of all items without + * nodes. + * + * For "standard" item addition, you can use playlist_Add(), playlist_AddExt() + * (more options) or playlist_AddInput() if you already created your input + * item. This will add the item at the root of "Playlist" or of "Media library" + * in each of the two trees. + * + * You can create nodes with playlist_NodeCreate() and can create items from + * existing input items to be placed under any node with + * playlist_NodeAddInput(). + * + * To delete an item, use playlist_NodeDelete( p_item ). + * + * The playlist defines the following event variables: + * + * - "item-change": It will contain a pointer to the input_item_t of a + * changed input item monitored by the playlist. + * + * - "playlist-item-append": It will contain a pointer to a playlist_item_t. + * - "playlist-item-deleted": It will contain a pointer to the playlist_item_t + * about to be deleted. + * + * - "leaf-to-parent": It will contain the playlist_item_t->i_id of an item that is transformed + * into a node. + * + * The playlist contains rate-variable which is propagated to current input if + * available also rate-slower/rate-faster is in use. + */ + +/** Helper structure to export to file part of the playlist */ +typedef struct playlist_export_t +{ + VLC_COMMON_MEMBERS + char *base_url; + FILE *p_file; + playlist_item_t *p_root; +} playlist_export_t; + +/** playlist item / node */ +struct playlist_item_t +{ + input_item_t *p_input; /**< Linked input item */ + + playlist_item_t **pp_children; /**< Children nodes/items */ + playlist_item_t *p_parent; /**< Item parent */ + int i_children; /**< Number of children, -1 if not a node */ + unsigned i_nb_played; /**< Times played */ + + int i_id; /**< Playlist item specific id */ + uint8_t i_flags; /**< Flags \see playlist_item_flags_e */ +}; + +typedef enum { + PLAYLIST_DBL_FLAG = 0x04, /**< Is it disabled ? */ + PLAYLIST_RO_FLAG = 0x08, /**< Write-enabled ? */ + PLAYLIST_SUBITEM_STOP_FLAG = 0x40, /**< Must playlist stop if the item gets subitems ?*/ + PLAYLIST_NO_INHERIT_FLAG = 0x80, /**< Will children inherit flags the R/O flag ? */ +} playlist_item_flags_e; + +/** Playlist status */ +typedef enum +{ PLAYLIST_STOPPED,PLAYLIST_RUNNING,PLAYLIST_PAUSED } playlist_status_t; + +/** Structure containing information about the playlist */ +struct playlist_t +{ + VLC_COMMON_MEMBERS + + playlist_item_array_t items; /**< Arrays of items */ + + playlist_item_array_t current; /**< Items currently being played */ + int i_current_index; /**< Index in current array */ + + /* Predefined items */ + playlist_item_t root; + playlist_item_t *p_playing; + playlist_item_t *p_media_library; +}; + +/* A bit of macro magic to generate an enum out of the following list, + * and later, to generate a list of static functions out of the same list. + * There is also SORT_RANDOM, which is always last and handled specially. + */ +#define VLC_DEFINE_SORT_FUNCTIONS \ + DEF( SORT_ID )\ + DEF( SORT_TITLE )\ + DEF( SORT_TITLE_NODES_FIRST )\ + DEF( SORT_ARTIST )\ + DEF( SORT_GENRE )\ + DEF( SORT_DURATION )\ + DEF( SORT_TITLE_NUMERIC )\ + DEF( SORT_ALBUM )\ + DEF( SORT_TRACK_NUMBER )\ + DEF( SORT_DESCRIPTION )\ + DEF( SORT_RATING )\ + DEF( SORT_URI )\ + DEF( SORT_DISC_NUMBER )\ + DEF( SORT_DATE ) + +#define DEF( s ) s, +enum +{ + VLC_DEFINE_SORT_FUNCTIONS + SORT_RANDOM, + NUM_SORT_FNS=SORT_RANDOM +}; +#undef DEF +#ifndef VLC_INTERNAL_PLAYLIST_SORT_FUNCTIONS +#undef VLC_DEFINE_SORT_FUNCTIONS +#endif + +enum +{ + ORDER_NORMAL = 0, + ORDER_REVERSE = 1, +}; + +#define PLAYLIST_END -1 + +enum pl_locked_state +{ + pl_Locked = true, + pl_Unlocked = false +}; + +/***************************************************************************** + * Prototypes + *****************************************************************************/ + +/* Helpers */ +#define PL_LOCK playlist_Lock( p_playlist ) +#define PL_UNLOCK playlist_Unlock( p_playlist ) +#define PL_ASSERT_LOCKED playlist_AssertLocked( p_playlist ) + +/** Playlist commands */ +enum { + PLAYLIST_PLAY, /**< No arg. res=can fail*/ + PLAYLIST_VIEWPLAY, /**< arg1= playlist_item_t*,*/ + /** arg2 = playlist_item_t* , res=can fail */ + PLAYLIST_TOGGLE_PAUSE, /**< No arg res=can fail */ + PLAYLIST_STOP, /**< No arg res=can fail*/ + PLAYLIST_SKIP, /**< arg1=int, res=can fail*/ + PLAYLIST_PAUSE, /**< No arg */ + PLAYLIST_RESUME, /**< No arg */ +}; + +#define playlist_Play(p) playlist_Control(p,PLAYLIST_PLAY, pl_Unlocked ) +#define playlist_TogglePause(p) \ + playlist_Control(p, PLAYLIST_TOGGLE_PAUSE, pl_Unlocked) +#define playlist_Stop(p) playlist_Control(p,PLAYLIST_STOP, pl_Unlocked ) +#define playlist_Next(p) playlist_Control(p,PLAYLIST_SKIP, pl_Unlocked, 1) +#define playlist_Prev(p) playlist_Control(p,PLAYLIST_SKIP, pl_Unlocked, -1) +#define playlist_Skip(p,i) playlist_Control(p,PLAYLIST_SKIP, pl_Unlocked, (i) ) +#define playlist_Pause(p) \ + playlist_Control(p, PLAYLIST_PAUSE, pl_Unlocked) +#define playlist_Resume(p) \ + playlist_Control(p, PLAYLIST_RESUME, pl_Unlocked) + +/** + * Locks the playlist. + * + * This function locks the playlist.

By contrast, the GNU General Public\n" +"License is intended to guarantee your freedom to share and change free\n" +"software--to make sure the software is free for all its users. This\n" +"General Public License applies to most of the Free Software\n" +"Foundation's software and to any other program whose authors commit to\n" +"using it. (Some other Free Software Foundation software is covered by\n" +"the GNU Lesser General Public License instead.) You can apply it to\n" +"your programs, too.\n" +"\n" +" When we speak of free software, we are referring to freedom, not\n" +"price. Our General Public Licenses are designed to make sure that you\n" +"have the freedom to distribute copies of free software (and charge for\n" +"this service if you wish), that you receive source code or can get it\n" +"if you want it, that you can change the software or use pieces of it\n" +"in new free programs; and that you know you can do these things.\n" +"\n" +" To protect your rights, we need to make restrictions that forbid\n" +"anyone to deny you these rights or to ask you to surrender the rights.\n" +"These restrictions translate to certain responsibilities for you if you\n" +"distribute copies of the software, or if you modify it.\n" +"\n" +" For example, if you distribute copies of such a program, whether\n" +"gratis or for a fee, you must give the recipients all the rights that\n" +"you have. You must make sure that they, too, receive or can get the\n" +"source code. And you must show them these terms so they know their\n" +"rights.\n" +"\n" +" We protect your rights with two steps: (1) copyright the software, and\n" +"(2) offer you this license which gives you legal permission to copy,\n" +"distribute and/or modify the software.\n" +"\n" +" Also, for each author's protection and ours, we want to make certain\n" +"that everyone understands that there is no warranty for this free\n" +"software. If the software is modified by someone else and passed on, we\n" +"want its recipients to know that what they have is not the original, so\n" +"that any problems introduced by others will not reflect on the original\n" +"authors' reputations.\n" +"\n" +" Finally, any free program is threatened constantly by software\n" +"patents. We wish to avoid the danger that redistributors of a free\n" +"program will individually obtain patent licenses, in effect making the\n" +"program proprietary. To prevent this, we have made it clear that any\n" +"patent must be licensed for everyone's free use or not licensed at all.\n" +"\n" +" The precise terms and conditions for copying, distribution and\n" +"modification follow.\n" +"\n" +" GNU GENERAL PUBLIC LICENSE\n" +" TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION\n" +"\n" +" 0. This License applies to any program or other work which contains\n" +"a notice placed by the copyright holder saying it may be distributed\n" +"under the terms of this General Public License. The \"Program\", below,\n" +"refers to any such program or work, and a \"work based on the Program\"\n" +"means either the Program or any derivative work under copyright law:\n" +"that is to say, a work containing the Program or a portion of it,\n" +"either verbatim or with modifications and/or translated into another\n" +"language. (Hereinafter, translation is included without limitation in\n" +"the term \"modification\".) Each licensee is addressed as \"you\".\n" +"\n" +"Activities other than copying, distribution and modification are not\n" +"covered by this License; they are outside its scope. The act of\n" +"running the Program is not restricted, and the output from the Program\n" +"is covered only if its contents constitute a work based on the\n" +"Program (independent of having been made by running the Program).\n" +"Whether that is true depends on what the Program does.\n" +"\n" +" 1. You may copy and distribute verbatim copies of the Program's\n" +"source code as you receive it, in any medium, provided that you\n" +"conspicuously and appropriately publish on each copy an appropriate\n" +"copyright notice and disclaimer of warranty; keep intact all the\n" +"notices that refer to this License and to the absence of any warranty;\n" +"and give any other recipients of the Program a copy of this License\n" +"along with the Program.\n" +"\n" +"You may charge a fee for the physical act of transferring a copy, and\n" +"you may at your option offer warranty protection in exchange for a fee.\n" +"\n" +" 2. You may modify your copy or copies of the Program or any portion\n" +"of it, thus forming a work based on the Program, and copy and\n" +"distribute such modifications or work under the terms of Section 1\n" +"above, provided that you also meet all of these conditions:\n" +"\n" +" a) You must cause the modified files to carry prominent notices\n" +" stating that you changed the files and the date of any change.\n" +"\n" +" b) You must cause any work that you distribute or publish, that in\n" +" whole or in part contains or is derived from the Program or any\n" +" part thereof, to be licensed as a whole at no charge to all third\n" +" parties under the terms of this License.\n" +"\n" +" c) If the modified program normally reads commands interactively\n" +" when run, you must cause it, when started running for such\n" +" interactive use in the most ordinary way, to print or display an\n" +" announcement including an appropriate copyright notice and a\n" +" notice that there is no warranty (or else, saying that you provide\n" +" a warranty) and that users may redistribute the program under\n" +" these conditions, and telling the user how to view a copy of this\n" +" License. (Exception: if the Program itself is interactive but\n" +" does not normally print such an announcement, your work based on\n" +" the Program is not required to print an announcement.)\n" +"\n" +"These requirements apply to the modified work as a whole. If\n" +"identifiable sections of that work are not derived from the Program,\n" +"and can be reasonably considered independent and separate works in\n" +"themselves, then this License, and its terms, do not apply to those\n" +"sections when you distribute them as separate works. But when you\n" +"distribute the same sections as part of a whole which is a work based\n" +"on the Program, the distribution of the whole must be on the terms of\n" +"this License, whose permissions for other licensees extend to the\n" +"entire whole, and thus to each and every part regardless of who wrote it.\n" +"\n" +"Thus, it is not the intent of this section to claim rights or contest\n" +"your rights to work written entirely by you; rather, the intent is to\n" +"exercise the right to control the distribution of derivative or\n" +"collective works based on the Program.\n" +"\n" +"In addition, mere aggregation of another work not based on the Program\n" +"with the Program (or with a work based on the Program) on a volume of\n" +"a storage or distribution medium does not bring the other work under\n" +"the scope of this License.\n" +"\n" +" 3. You may copy and distribute the Program (or a work based on it,\n" +"under Section 2) in object code or executable form under the terms of\n" +"Sections 1 and 2 above provided that you also do one of the following:\n" +"\n" +" a) Accompany it with the complete corresponding machine-readable\n" +" source code, which must be distributed under the terms of Sections\n" +" 1 and 2 above on a medium customarily used for software interchange; or,\n" +"\n" +" b) Accompany it with a written offer, valid for at least three\n" +" years, to give any third party, for a charge no more than your\n" +" cost of physically performing source distribution, a complete\n" +" machine-readable copy of the corresponding source code, to be\n" +" distributed under the terms of Sections 1 and 2 above on a medium\n" +" customarily used for software interchange; or,\n" +"\n" +" c) Accompany it with the information you received as to the offer\n" +" to distribute corresponding source code. (This alternative is\n" +" allowed only for noncommercial distribution and only if you\n" +" received the program in object code or executable form with such\n" +" an offer, in accord with Subsection b above.)\n" +"\n" +"The source code for a work means the preferred form of the work for\n" +"making modifications to it. For an executable work, complete source\n" +"code means all the source code for all modules it contains, plus any\n" +"associated interface definition files, plus the scripts used to\n" +"control compilation and installation of the executable. However, as a\n" +"special exception, the source code distributed need not include\n" +"anything that is normally distributed (in either source or binary\n" +"form) with the major components (compiler, kernel, and so on) of the\n" +"operating system on which the executable runs, unless that component\n" +"itself accompanies the executable.\n" +"\n" +"If distribution of executable or object code is made by offering\n" +"access to copy from a designated place, then offering equivalent\n" +"access to copy the source code from the same place counts as\n" +"distribution of the source code, even though third parties are not\n" +"compelled to copy the source along with the object code.\n" +"\n" +" 4. You may not copy, modify, sublicense, or distribute the Program\n" +"except as expressly provided under this License. Any attempt\n" +"otherwise to copy, modify, sublicense or distribute the Program is\n" +"void, and will automatically terminate your rights under this License.\n" +"However, parties who have received copies, or rights, from you under\n" +"this License will not have their licenses terminated so long as such\n" +"parties remain in full compliance.\n" +"\n" +" 5. You are not required to accept this License, since you have not\n" +"signed it. However, nothing else grants you permission to modify or\n" +"distribute the Program or its derivative works. These actions are\n" +"prohibited by law if you do not accept this License. Therefore, by\n" +"modifying or distributing the Program (or any work based on the\n" +"Program), you indicate your acceptance of this License to do so, and\n" +"all its terms and conditions for copying, distributing or modifying\n" +"the Program or works based on it.\n" +"\n" +" 6. Each time you redistribute the Program (or any work based on the\n" +"Program), the recipient automatically receives a license from the\n" +"original licensor to copy, distribute or modify the Program subject to\n" +"these terms and conditions. You may not impose any further\n" +"restrictions on the recipients' exercise of the rights granted herein.\n" +"You are not responsible for enforcing compliance by third parties to\n" +"this License.\n" +"\n" +" 7. If, as a consequence of a court judgment or allegation of patent\n" +"infringement or for any other reason (not limited to patent issues),\n" +"conditions are imposed on you (whether by court order, agreement or\n" +"otherwise) that contradict the conditions of this License, they do not\n" +"excuse you from the conditions of this License. If you cannot\n" +"distribute so as to satisfy simultaneously your obligations under this\n" +"License and any other pertinent obligations, then as a consequence you\n" +"may not distribute the Program at all. For example, if a patent\n" +"license would not permit royalty-free redistribution of the Program by\n" +"all those who receive copies directly or indirectly through you, then\n" +"the only way you could satisfy both it and this License would be to\n" +"refrain entirely from distribution of the Program.\n" +"\n" +"If any portion of this section is held invalid or unenforceable under\n" +"any particular circumstance, the balance of the section is intended to\n" +"apply and the section as a whole is intended to apply in other\n" +"circumstances.\n" +"\n" +"It is not the purpose of this section to induce you to infringe any\n" +"patents or other property right claims or to contest validity of any\n" +"such claims; this section has the sole purpose of protecting the\n" +"integrity of the free software distribution system, which is\n" +"implemented by public license practices. Many people have made\n" +"generous contributions to the wide range of software distributed\n" +"through that system in reliance on consistent application of that\n" +"system; it is up to the author/donor to decide if he or she is willing\n" +"to distribute software through any other system and a licensee cannot\n" +"impose that choice.\n" +"\n" +"This section is intended to make thoroughly clear what is believed to\n" +"be a consequence of the rest of this License.\n" +"\n" +" 8. If the distribution and/or use of the Program is restricted in\n" +"certain countries either by patents or by copyrighted interfaces, the\n" +"original copyright holder who places the Program under this License\n" +"may add an explicit geographical distribution limitation excluding\n" +"those countries, so that distribution is permitted only in or among\n" +"countries not thus excluded. In such case, this License incorporates\n" +"the limitation as if written in the body of this License.\n" +"\n" +" 9. The Free Software Foundation may publish revised and/or new versions\n" +"of the General Public License from time to time. Such new versions will\n" +"be similar in spirit to the present version, but may differ in detail to\n" +"address new problems or concerns.\n" +"\n" +"Each version is given a distinguishing version number. If the Program\n" +"specifies a version number of this License which applies to it and \"any\n" +"later version\", you have the option of following the terms and conditions\n" +"either of that version or of any later version published by the Free\n" +"Software Foundation. If the Program does not specify a version number of\n" +"this License, you may choose any version ever published by the Free Software\n" +"Foundation.\n" +"\n" +" 10. If you wish to incorporate parts of the Program into other free\n" +"programs whose distribution conditions are different, write to the author\n" +"to ask for permission. For software which is copyrighted by the Free\n" +"Software Foundation, write to the Free Software Foundation; we sometimes\n" +"make exceptions for this. Our decision will be guided by the two goals\n" +"of preserving the free status of all derivatives of our free software and\n" +"of promoting the sharing and reuse of software generally.\n" +"\n" +" NO WARRANTY\n" +"\n" +" 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY\n" +"FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN\n" +"OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES\n" +"PROVIDE THE PROGRAM \"AS IS\" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED\n" +"OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF\n" +"MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS\n" +"TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE\n" +"PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,\n" +"REPAIR OR CORRECTION.\n" +"\n" +" 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING\n" +"WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR\n" +"REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,\n" +"INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING\n" +"OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED\n" +"TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY\n" +"YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER\n" +"PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE\n" +"POSSIBILITY OF SUCH DAMAGES.\n" +"\n" +" END OF TERMS AND CONDITIONS\n" +"\n" +" How to Apply These Terms to Your New Programs\n" +"\n" +" If you develop a new program, and you want it to be of the greatest\n" +"possible use to the public, the best way to achieve this is to make it\n" +"free software which everyone can redistribute and change under these terms.\n" +"\n" +" To do so, attach the following notices to the program. It is safest\n" +"to attach them to the start of each source file to most effectively\n" +"convey the exclusion of warranty; and each file should have at least\n" +"the \"copyright\" line and a pointer to where the full notice is found.\n" +"\n" +" \n" +" Copyright (C) \n" +"\n" +" This program is free software; you can redistribute it and/or modify\n" +" it under the terms of the GNU General Public License as published by\n" +" the Free Software Foundation; either version 2 of the License, or\n" +" (at your option) any later version.\n" +"\n" +" This program is distributed in the hope that it will be useful,\n" +" but WITHOUT ANY WARRANTY; without even the implied warranty of\n" +" MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

This allows advanced + * categorization, like for SAP streams (which are grouped by "sap groups"). + * + * The base structure for all playlist operations is the playlist_item_t. + * This is essentially a node within the playlist tree. Each playlist item + * references an input_item_t which contains the input stream info, such as + * location, name and meta-data. + * + * A playlist item is uniquely identified by its input item: + * \ref playlist_ItemGetByInput(). A single input item cannot be used by more + * than one playlist item at a time; if necessary, a copy of the input item can + * be made instead. + * + * The same playlist tree is visible to all user interfaces. To arbitrate + * access, a lock is used, see \ref playlist_Lock() and \ref playlist_Unlock(). + * + * Under the playlist root item node, the top-level items are the main + * media sources and include: + * - the actual playlist, + * - the media library, + * - the service discovery root node, whose children are services discovery + * module instances. + * + * So, here is an example: + * \verbatim + * Inputs array + * - input 1 -> name = foo 1 uri = ... + * - input 2 -> name = foo 2 uri = ... + * + * Playlist items tree + * - playlist (id 1) + * - category 1 (id 2) + * - foo 2 (id 6 - input 2) + * - media library (id 2) + * - foo 1 (id 5 - input 1) + * \endverbatim + * + * Sometimes, an item creates subitems. This happens for the directory access + * for example. In that case, if the item is under the "playlist" top-level + * item and playlist is configured to be flat then the item will be deleted and + * replaced with new subitems. If the item is under another top-level item, it + * will be transformed to a node and removed from the list of all items without + * nodes. + * + * For "standard" item addition, you can use playlist_Add(), playlist_AddExt() + * (more options) or playlist_AddInput() if you already created your input + * item. This will add the item at the root of "Playlist" or of "Media library" + * in each of the two trees. + * + * You can create nodes with playlist_NodeCreate() and can create items from + * existing input items to be placed under any node with + * playlist_NodeAddInput(). + * + * To delete an item, use playlist_NodeDelete( p_item ). + * + * The playlist defines the following event variables: + * + * - "item-change": It will contain a pointer to the input_item_t of a + * changed input item monitored by the playlist. + * + * - "playlist-item-append": It will contain a pointer to a playlist_item_t. + * - "playlist-item-deleted": It will contain a pointer to the playlist_item_t + * about to be deleted. + * + * - "leaf-to-parent": It will contain the playlist_item_t->i_id of an item that is transformed + * into a node. + * + * The playlist contains rate-variable which is propagated to current input if + * available also rate-slower/rate-faster is in use. + */ + +/** Helper structure to export to file part of the playlist */ +typedef struct playlist_export_t +{ + VLC_COMMON_MEMBERS + char *base_url; + FILE *p_file; + playlist_item_t *p_root; +} playlist_export_t; + +/** playlist item / node */ +struct playlist_item_t +{ + input_item_t *p_input; /**< Linked input item */ + + playlist_item_t **pp_children; /**< Children nodes/items */ + playlist_item_t *p_parent; /**< Item parent */ + int i_children; /**< Number of children, -1 if not a node */ + unsigned i_nb_played; /**< Times played */ + + int i_id; /**< Playlist item specific id */ + uint8_t i_flags; /**< Flags \see playlist_item_flags_e */ +}; + +typedef enum { + PLAYLIST_DBL_FLAG = 0x04, /**< Is it disabled ? */ + PLAYLIST_RO_FLAG = 0x08, /**< Write-enabled ? */ + PLAYLIST_SUBITEM_STOP_FLAG = 0x40, /**< Must playlist stop if the item gets subitems ?*/ + PLAYLIST_NO_INHERIT_FLAG = 0x80, /**< Will children inherit flags the R/O flag ? */ +} playlist_item_flags_e; + +/** Playlist status */ +typedef enum +{ PLAYLIST_STOPPED,PLAYLIST_RUNNING,PLAYLIST_PAUSED } playlist_status_t; + +/** Structure containing information about the playlist */ +struct playlist_t +{ + VLC_COMMON_MEMBERS + + playlist_item_array_t items; /**< Arrays of items */ + + playlist_item_array_t current; /**< Items currently being played */ + int i_current_index; /**< Index in current array */ + + /* Predefined items */ + playlist_item_t root; + playlist_item_t *p_playing; + playlist_item_t *p_media_library; +}; + +/* A bit of macro magic to generate an enum out of the following list, + * and later, to generate a list of static functions out of the same list. + * There is also SORT_RANDOM, which is always last and handled specially. + */ +#define VLC_DEFINE_SORT_FUNCTIONS \ + DEF( SORT_ID )\ + DEF( SORT_TITLE )\ + DEF( SORT_TITLE_NODES_FIRST )\ + DEF( SORT_ARTIST )\ + DEF( SORT_GENRE )\ + DEF( SORT_DURATION )\ + DEF( SORT_TITLE_NUMERIC )\ + DEF( SORT_ALBUM )\ + DEF( SORT_TRACK_NUMBER )\ + DEF( SORT_DESCRIPTION )\ + DEF( SORT_RATING )\ + DEF( SORT_URI )\ + DEF( SORT_DISC_NUMBER )\ + DEF( SORT_DATE ) + +#define DEF( s ) s, +enum +{ + VLC_DEFINE_SORT_FUNCTIONS + SORT_RANDOM, + NUM_SORT_FNS=SORT_RANDOM +}; +#undef DEF +#ifndef VLC_INTERNAL_PLAYLIST_SORT_FUNCTIONS +#undef VLC_DEFINE_SORT_FUNCTIONS +#endif + +enum +{ + ORDER_NORMAL = 0, + ORDER_REVERSE = 1, +}; + +#define PLAYLIST_END -1 + +enum pl_locked_state +{ + pl_Locked = true, + pl_Unlocked = false +}; + +/***************************************************************************** + * Prototypes + *****************************************************************************/ + +/* Helpers */ +#define PL_LOCK playlist_Lock( p_playlist ) +#define PL_UNLOCK playlist_Unlock( p_playlist ) +#define PL_ASSERT_LOCKED playlist_AssertLocked( p_playlist ) + +/** Playlist commands */ +enum { + PLAYLIST_PLAY, /**< No arg. res=can fail*/ + PLAYLIST_VIEWPLAY, /**< arg1= playlist_item_t*,*/ + /** arg2 = playlist_item_t* , res=can fail */ + PLAYLIST_TOGGLE_PAUSE, /**< No arg res=can fail */ + PLAYLIST_STOP, /**< No arg res=can fail*/ + PLAYLIST_SKIP, /**< arg1=int, res=can fail*/ + PLAYLIST_PAUSE, /**< No arg */ + PLAYLIST_RESUME, /**< No arg */ +}; + +#define playlist_Play(p) playlist_Control(p,PLAYLIST_PLAY, pl_Unlocked ) +#define playlist_TogglePause(p) \ + playlist_Control(p, PLAYLIST_TOGGLE_PAUSE, pl_Unlocked) +#define playlist_Stop(p) playlist_Control(p,PLAYLIST_STOP, pl_Unlocked ) +#define playlist_Next(p) playlist_Control(p,PLAYLIST_SKIP, pl_Unlocked, 1) +#define playlist_Prev(p) playlist_Control(p,PLAYLIST_SKIP, pl_Unlocked, -1) +#define playlist_Skip(p,i) playlist_Control(p,PLAYLIST_SKIP, pl_Unlocked, (i) ) +#define playlist_Pause(p) \ + playlist_Control(p, PLAYLIST_PAUSE, pl_Unlocked) +#define playlist_Resume(p) \ + playlist_Control(p, PLAYLIST_RESUME, pl_Unlocked) + +/** + * Locks the playlist. + * + * This function locks the playlist.
