- * IMPORTANT: The official FFmpeg C headers change very quickly. Often some

- * necessarily related to video or audio due to buffer overflows etc.) might

- * for the game if the MAX. VERSION WAS CHANGED.
- *
- * The only safe way to support new versions of FFmpeg is to add the changes
- * of the FFmpeg git repository C headers to the Pascal headers.
- * You can accelerate this process by posting a patch with the git changes
- * translated to Pascal to our bug tracker (please join our IRC chat before

- * @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.

- * This callback is called at the beginning of each frame to get data

- * this means is, you may set however many entries in buf[] you feel necessary.
- * Each buffer must be reference-counted using the AVBuffer API (see description
- * of buf[] below).
- *
- * The following fields will be set in the frame before this callback is
- * called:
- * - format
- * - width, height (video only)
- * - sample_rate, channel_layout, nb_samples (audio only)
- * Their values may differ from the corresponding values in
- * AVCodecContext. This callback must use the frame values, not the codec
- * 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.
- *
- * Each data plane must be aligned to the maximum required by the target
- * CPU.

- *
- * Video:
- *
- * If AV_GET_BUFFER_FLAG_REF is set in flags then the frame may be reused
- * (read and/or written to if it is writable) later by libavcodec.
- *
- * avcodec_align_dimensions2() should be used to find the required width and
- * 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,
- * this callback may be called from a different thread, but not from more
- * than one at once. Does not need to be reentrant.

- *
- * As a convenience, av_samples_get_buffer_size() and
- * av_samples_fill_arrays() in libavutil may be used by custom get_buffer2()

- * 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.

- * Not changed if an error is returned.

- * 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). 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

- * @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 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".
- *
- * - 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.

- * @
- * 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).

- * AVBufferPool is an API for a lock-free thread-safe pool of AVBuffers.
- *
- * Frequently allocating and freeing large buffers may be slow. AVBufferPool is
- * meant to solve this in cases when the caller needs a set of buffers of the
- * same size (the most obvious use case being buffers for raw video or audio
- * frames).
- *
- * At the beginning, the user must call av_buffer_pool_init() to create the
- * buffer pool. Then whenever a buffer is needed, call av_buffer_pool_get() to
- * get a reference to a new buffer, similar to av_buffer_alloc(). This new
- * reference works in all aspects the same way as the one created by
- * av_buffer_alloc(). However, when the last reference to this buffer is
- * unreferenced, it is returned to the pool instead of being freed and will be
- * reused for subsequent av_buffer_pool_get() calls.
- *
- * When the caller is done with the pool and no longer needs to allocate any new
- * buffers, av_buffer_pool_uninit() must be called to mark the pool as freeable.
- * Once all the buffers are released, it will automatically be freed.
- *
- * Allocating and releasing buffers with this API is thread-safe as long as
- * either the default alloc callback is used, or the user-supplied one is
- * thread-safe.

- *
- * Utilities to make an array grow when needed.
- *
- * Sometimes, the programmer would want to have an array that can grow when
- * needed. The libavutil dynamic array utilities fill that need.
- *
- * libavutil supports two systems of appending elements onto a dynamically
- * allocated array, the first one storing the pointer to the value in the
- * array, and the second storing the value directly. In both systems, the
- * caller is responsible for maintaining a variable containing the length of
- * the array, as well as freeing of the array after use.
- *
- * The first system stores pointers to values in a block of dynamically
- * allocated memory. Since only pointers are stored, the function does not need
- * to know the size of the type. Both av_dynarray_add() and
- * av_dynarray_add_nofree() implement this system.
- *
- * @code
- * type **array = NULL; //< an array of pointers to values
- * int nb = 0; //< a variable to keep track of the length of the array
- *
- * type to_be_added = ...;
- * type to_be_added2 = ...;
- *
- * av_dynarray_add(&array, &nb, &to_be_added);
- * if (nb == 0)
- * return AVERROR(ENOMEM);
- *
- * av_dynarray_add(&array, &nb, &to_be_added2);
- * if (nb == 0)
- * return AVERROR(ENOMEM);
- *
- * // Now:
- * // nb == 2
- * // &to_be_added == array[0]
- * // &to_be_added2 == array[1]
- *
- * av_freep(&array);
- * @endcode
- *
- * The second system stores the value directly in a block of memory. As a
- * result, the function has to know the size of the type. av_dynarray2_add()
- * implements this mechanism.
- *
- * @code
- * type *array = NULL; //< an array of values
- * int nb = 0; //< a variable to keep track of the length of the array
- *
- * type to_be_added = ...;
- * type to_be_added2 = ...;
- *
- * type *addr = av_dynarray2_add((void ** )&array, &nb, sizeof(*array), NULL);
- * if (!addr)
- * return AVERROR(ENOMEM);
- * memcpy(addr, &to_be_added, sizeof(to_be_added));
- *
- * // Shortcut of the above.
- * type *addr = av_dynarray2_add((void ** )&array, &nb, sizeof(*array),
- * (const void * )&to_be_added2);
- * if (!addr)

- * Pixel format. Notes:
- *
- * @note
- * AV_PIX_FMT_RGB32 is handled in an endian-specific manner. An RGBA
- * color is put together as:
- * (A << 24) | (R << 16) | (G << 8) | B
- * This is stored as BGRA on little-endian CPU architectures and ARGB on
- * big-endian CPUs.
- *
- * @par
- * When the pixel format is palettized RGB32 (AV_PIX_FMT_PAL8), the palettized
- * image data is stored in AVFrame.data[0]. The palette is transported in
- * AVFrame.data[1], is 1024 bytes long (256 4-byte entries) and is
- * formatted the same as in AV_PIX_FMT_RGB32 described above (i.e., it is
- * also endian-specific). Note also that the individual RGB32 palette
- * components stored in AVFrame.data[1] should be in the range 0..255.
- * This is important as many custom PAL8 video codecs that were designed
- * to run on the IBM VGA graphics adapter use 6-bit palette components.
- *
- * @par
- * For all the 8 bits per pixel formats, an RGB32 palette is in data[1] like
- * for pal8. This palette is filled in automatically by the function
- * allocating the picture.

- * Audio sample formats

- * - The data described by the sample format is always in native-endian order.
- * Sample values can be expressed by native C types, hence the lack of a signed
- * 24-bit sample format even though it is a common raw audio data format.
- *
- * - The floating-point formats are based on full volume being in the range
- * [-1.0, 1.0]. Any values outside this range are beyond full volume level.
- *
- * - The data layout as used in av_samples_fill_arrays() and elsewhere in FFmpeg
- * (such as AVFrame in libavcodec) is as follows:
- *
- * @par
- * For planar sample formats, each audio channel is in a separate data plane,
- * and linesize is the buffer size, in bytes, for a single plane. All data
- * planes must be the same size. For packed sample formats, only the first data
- * plane is used, and samples for each channel are interleaved. In this case,
- * linesize is the buffer size, in bytes, for the 1 plane.

- * IMPORTANT: The official FFmpeg C headers change very quickly. Often some
- * of the data structures are changed so that they become incompatible with
- * older header files. The Pascal headers have to be adjusted to those changes,
- * otherwise the application might crash randomly or strange bugs (not
- * necessarily related to video or audio due to buffer overflows etc.) might
- * occur.
- *
- * In the past users reported problems with USDX that took hours to fix and
- * the problem was an unsupported version of FFmpeg. So we decided to disable
- * support for future versions of FFmpeg until the headers are revised by us
- * for that version as they otherwise most probably will break USDX.
- *
- * If the headers do not yet support your FFmpeg version you may want to
- * adjust the max. version numbers manually but please note: it may work but
- * in many cases it does not. The USDX team does NOT PROVIDE ANY SUPPORT
- * for the game if the MAX. VERSION WAS CHANGED.
- *
- * The only safe way to support new versions of FFmpeg is to add the changes
- * of the FFmpeg git repository C headers to the Pascal headers.
- * You can accelerate this process by posting a patch with the git changes
- * translated to Pascal to our bug tracker (please join our IRC chat before
- * you start working on it). Simply adjusting the max. versions is NOT a valid

- * IMPORTANT: The official FFmpeg C headers change very quickly. Often some
- * of the data structures are changed so that they become incompatible with
- * older header files. The Pascal headers have to be adjusted to those changes,
- * otherwise the application might crash randomly or strange bugs (not
- * necessarily related to video or audio due to buffer overflows etc.) might
- * occur.
- *
- * In the past users reported problems with USDX that took hours to fix and
- * the problem was an unsupported version of FFmpeg. So we decided to disable
- * support for future versions of FFmpeg until the headers are revised by us
- * for that version as they otherwise most probably will break USDX.
- *
- * If the headers do not yet support your FFmpeg version you may want to
- * adjust the max. version numbers manually but please note: it may work but
- * in many cases it does not. The USDX team does NOT PROVIDE ANY SUPPORT
- * for the game if the MAX. VERSION WAS CHANGED.
- *
- * The only safe way to support new versions of FFmpeg is to add the changes
- * of the FFmpeg git repository C headers to the Pascal headers.
- * You can accelerate this process by posting a patch with the git changes
- * translated to Pascal to our bug tracker (please join our IRC chat before
- * you start working on it). Simply adjusting the max. versions is NOT a valid
- * fix.
