-/**
- * @ingroup libavc
- * @defgroup lavc_encdec send/receive encoding and decoding API overview
- * @{
- *
- * The avcodec_send_packet()/avcodec_receive_frame()/avcodec_send_frame()/
- * avcodec_receive_packet() functions provide an encode/decode API, which
- * decouples input and output.
- *
- * The API is very similar for encoding/decoding and audio/video, and works as
- * follows:
- * - Set up and open the AVCodecContext as usual.
- * - Send valid input:
- * - For decoding, call avcodec_send_packet() to give the decoder raw
- * compressed data in an AVPacket.
- * - For encoding, call avcodec_send_frame() to give the encoder an AVFrame
- * containing uncompressed audio or video.
- *
- * In both cases, it is recommended that AVPackets and AVFrames are
- * refcounted, or libavcodec might have to copy the input data. (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.

- * - width, height (video only)
- * - sample_rate, channel_layout, nb_samples (audio only)
- * Their values may differ from the corresponding values in

- * context values, to calculate the required buffer size.
- *
- * This callback must fill the following fields in the frame:
- * - data[]
- * - linesize[]
- * - extended_data:
- * * if the data is planar audio with more than 8 channels, then this
- * callback must allocate and fill extended_data to contain all pointers
- * to all data planes. data[] must hold as many pointers as it can.
- * extended_data must be allocated with av_malloc() and will be freed in
- * av_frame_unref().
- * * otherwise extended_data must point to data
- * - buf[] must contain one or more pointers to AVBufferRef structures. Each of
- * the frame's data and extended_data pointers must be contained in these. That
- * is, one AVBufferRef for each allocated chunk of memory, not necessarily one
- * AVBufferRef per data[] entry. See: av_buffer_create(), av_buffer_alloc(),
- * and av_buffer_ref().
- * - extended_buf and nb_extended_buf must be allocated with av_malloc() by
- * this callback and filled with the extra buffers if there are more
- * buffers than buf[] can hold. extended_buf will be freed in
- * av_frame_unref().
- *
- * If AV_CODEC_CAP_DR1 is not set then get_buffer2() must call
- * avcodec_default_get_buffer2() instead of providing buffers allocated by
- * some other means.

- * height, as they normally need to be rounded up to the next multiple of 16.
- *
- * Some decoders do not support linesizes changing between frames.
- *
- * If frame multithreading is used and thread_safe_callbacks is set,

-/**
- * Create and return a AVHWFramesContext with values adequate for hardware
- * decoding. This is meant to get called from the get_format callback, and is
- * a helper for preparing a AVHWFramesContext for AVCodecContext.hw_frames_ctx.
- * This API is for decoding with certain hardware acceleration modes/APIs only.
- *
- * The returned AVHWFramesContext is not initialized. The caller must do this
- * with av_hwframe_ctx_init().
- *
- * Calling this function is not a requirement, but makes it simpler to avoid
- * codec or hardware API specific details when manually allocating frames.
- *
- * Alternatively to this, an API user can set AVCodecContext.hw_device_ctx,
- * which sets up AVCodecContext.hw_frames_ctx fully automatically, and makes
- * it unnecessary to call this function or having to care about
- * AVHWFramesContext initialization at all.
- *
- * There are a number of requirements for calling this function:
- *
- * - It must be called from get_format with the same avctx parameter that was
- * passed to get_format. Calling it outside of get_format is not allowed, and
- * can trigger undefined behavior.
- * - The function is not always supported (see description of return values).
- * Even if this function returns successfully, hwaccel initialization could
- * fail later. (The degree to which implementations check whether the stream
- * is actually supported varies. Some do this check only after the user's
- * get_format callback returns.)
- * - The hw_pix_fmt must be one of the choices suggested by get_format. If the
- * user decides to use a AVHWFramesContext prepared with this API function,
- * the user must return the same hw_pix_fmt from get_format.
- * - The device_ref passed to this function must support the given hw_pix_fmt.
- * - After calling this API function, it is the user's responsibility to
- * initialize the AVHWFramesContext (returned by the out_frames_ref parameter),
- * and to set AVCodecContext.hw_frames_ctx to it. If done, this must be done
- * before returning from get_format (this is implied by the normal
- * AVCodecContext.hw_frames_ctx API rules).
- * - The AVHWFramesContext parameters may change every time time get_format is
- * called. Also, AVCodecContext.hw_frames_ctx is reset before get_format. So
- * you are inherently required to go through this process again on every
- * get_format call.
- * - It is perfectly possible to call this function without actually using
- * the resulting AVHWFramesContext. One use-case might be trying to reuse a
- * previously initialized AVHWFramesContext, and calling this API function
- * only to test whether the required frame parameters have changed.
- * - Fields that use dynamically allocated values of any kind must not be set
- * by the user unless setting them is explicitly allowed by the documentation.
- * If the user sets AVHWFramesContext.free and AVHWFramesContext.user_opaque,
- * the new free callback must call the potentially set previous free callback.
- * This API call may set any dynamically allocated fields, including the free
- * callback.
- *
- * The function will set at least the following fields on AVHWFramesContext
- * (potentially more, depending on hwaccel API):
- *
- * - All fields set by av_hwframe_ctx_alloc().
- * - Set the format field to hw_pix_fmt.
- * - Set the sw_format field to the most suited and most versatile format. (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. If the hwaccel does not require pre-allocation, the
- * field is left to 0, and the decoder will allocate new surfaces on demand
- * during decoding.
- * - Possibly AVHWFramesContext.hwctx fields, depending on the underlying
- * hardware API.
- *
- * Essentially, out_frames_ref returns the same as av_hwframe_ctx_alloc(), but
- * with basic frame parameters set.
- *
- * The function is stateless, and does not change the AVCodecContext or the
- * device_ref AVHWDeviceContext.
- *
- * @param avctx The context which is currently calling get_format, and which
- * implicitly contains all state needed for filling the returned
- * AVHWFramesContext properly.
- * @param device_ref A reference to the AVHWDeviceContext describing the device
- * which will be used by the hardware decoder.
- * @param hw_pix_fmt The hwaccel format you are going to return from get_format.
- * @param out_frames_ref On success, set to a reference to an _uninitialized_
- * AVHWFramesContext, created from the given device_ref.
- * Fields will be set to values required for decoding.
- * Not changed if an error is returned.
- * @return zero on success, a negative value on error. The following error codes
- * have special semantics:
- * AVERROR(ENOENT): the decoder does not support this functionality. Setup
- * is always manual, or it is a decoder which does not
- * support setting AVCodecContext.hw_frames_ctx at all,
- * or it is a software format.
- * AVERROR(EINVAL): it is known that hardware decoding is not supported for
- * this configuration, or the device_ref is not supported
- * for the hwaccel referenced by hw_pix_fmt.

-/**
- * @defgroup libavf libavformat
- * I/O and Muxing/Demuxing Library
- *
- * Libavformat (lavf) is a library for dealing with various media container
- * formats. 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.
- *
- * A packet returned by av_read_frame() is always reference-counted,
- * i.e. AVPacket.buf is set and the user may keep it indefinitely.
- * 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 metadata_api Public Metadata API
- * @{
- * @ingroup libavf
- * The metadata API allows libavformat to export metadata tags to a client
- * application when demuxing. 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

- *
- * @section ffmpeg_intro Introduction
- *
- * This document describes the usage of the different libraries
- * provided by FFmpeg.
- *
- * @li @ref libavc "libavcodec" encoding/decoding library
- * @li @ref lavfi "libavfilter" graph-based frame editing library
- * @li @ref libavf "libavformat" I/O and muxing/demuxing library
- * @li @ref lavd "libavdevice" special devices muxing/demuxing library

- * @li @ref lswr "libswresample" audio resampling, format conversion and mixing
- * @li @ref lpp "libpostproc" post processing library
- * @li @ref libsws "libswscale" color conversion and scaling library
- *
- * @section ffmpeg_versioning Versioning and compatibility
- *
- * Each of the FFmpeg libraries contains a version.h header, which defines a
- * major, minor and micro version number with the
- * LIBRARYNAME_VERSION_{MAJOR,MINOR,MICRO} macros. The major version
- * number is incremented with backward incompatible changes - e.g. removing
- * parts of the public API, reordering public struct members, etc. The minor
- * version number is incremented for backward compatible API changes or major
- * new features - e.g. adding a new public function or a new decoder. The micro
- * version number is incremented for smaller changes that a calling program
- * might still want to check for - e.g. changing behavior in a previously
- * unspecified situation.
- *
- * FFmpeg guarantees backward API and ABI compatibility for each library as long
- * as its major version number is unchanged. This means that no public symbols
- * will be removed or renamed. Types and names of the public struct members and
- * values of public macros and enums will remain the same (unless they were
- * explicitly declared as not part of the public API). Documented behavior will
- * not change.
- *
- * In other words, any correct program that works with a given FFmpeg snapshot
- * should work just as well without any changes with any later snapshot with the
- * same major versions. This applies to both rebuilding the program against new
- * FFmpeg versions or to replacing the dynamic FFmpeg libraries that a program
- * links against.
- *
- * However, new public symbols may be added and new members may be appended to
- * public structs whose size is not part of public ABI (most public structs in
- * FFmpeg). New macros and enum values may be added. Behavior in undocumented
- * situations may change slightly (and be documented). All those are accompanied
- * by an entry in doc/APIchanges and incrementing either the minor or micro
- * version number.

- *
- * Small buffers are kept in the structure itself, and thus require no

- * The length of the string can go beyond the allocated size: the buffer is
- * then truncated, but the functions still keep account of the actual total
- * length.

- * In other words, buf->len can be greater than buf->size and records the
- * total length of what would have been to the buffer if there had been
- * enough memory.

- * Append operations do not need to be tested for failure: if a memory
- * allocation fails, data stop being appended to the buffer, but the length
- * is still updated. This situation can be tested with

- *
- * The size_max field determines several possible behaviours:
- *
- * size_max = -1 (= UINT_MAX) or any large value will let the buffer be
- * reallocated as necessary, with an amortized linear cost.
- *
- * size_max = 0 prevents writing anything to the buffer: only the total
- * length is computed. The write operations can then possibly be repeated in
- * a buffer with exactly the necessary size
- * (using size_init = size_max = len + 1).
- *
- * size_max = 1 is automatically replaced by the exact size available in the

- *
- * @{
- * AVBuffer is an API for reference-counted data buffers.
- *
- * There are two core objects in this API -- AVBuffer and AVBufferRef. AVBuffer
- * represents the data buffer itself; it is opaque and not meant to be accessed
- * by the caller directly, but only through AVBufferRef. However, the caller may
- * e.g. compare two AVBuffer pointers to check whether two different references
- * are describing the same data buffer. AVBufferRef represents a single
- * reference to an AVBuffer and it is the object that may be manipulated by the
- * caller directly.
- *
- * There are two functions provided for creating a new AVBuffer with a single
- * reference -- av_buffer_alloc() to just allocate a new buffer, and
- * av_buffer_create() to wrap an existing array in an AVBuffer. From an existing
- * reference, additional references may be created with av_buffer_ref().
- * Use av_buffer_unref() to free a reference (this will automatically free the
- * data once all the references are freed).
- *
- * The convention throughout this API and the rest of FFmpeg is such that the
- * buffer is considered writable if there exists only one reference to it (and
- * it has not been marked as read-only). The av_buffer_is_writable() function is
- * provided to check whether this is true and av_buffer_make_writable() will
- * automatically create a new writable buffer when necessary.
- * Of course nothing prevents the calling code from violating this convention,
- * however that is safe only when all the existing references are under its
- * control.
- *
- * @note Referencing and unreferencing the buffers is thread-safe and thus
- * may be done from multiple threads simultaneously without any need for
- * additional locking.
- *
- * @note Two different references to the same buffer can point to different
- * parts of the buffer (i.e. their AVBufferRef.data will not be equal).
