+Description: a library to decode, encode, transcode, mux, demux, stream, filter and play pretty much anything that humans and machines have created.
+ FFmpeg is the leading multimedia framework, able to decode, encode, transcode, mux, demux, stream, filter and play pretty much anything that humans and machines have created. It supports the most obscure ancient formats up to the cutting edge. No matter if they were designed by some standards committee, the community or a corporation. It is also highly portable: FFmpeg compiles, runs, and passes our testing infrastructure FATE across Linux, Mac OS X, Microsoft Windows, the BSDs, Solaris, etc. under a wide variety of build environments, machine architectures, and configurations.

+/**
+ * @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

+ * 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

+ *
+ * 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

+ * 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, this callback may be called from a

+ *

+ * 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().

+ * - a recursive media finder providing a player with an ability to play all

+ * @subsection lavf_io_dirlist_open Opening a directory
+ * At first, a directory needs to be opened by calling avio_open_dir()

+/**
+ * @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_frame(), 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

+ *
+ * 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 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
+ * memory allocation at all (unless the contents of the buffer is needed
+ * after the structure goes out of scope). This is almost as lightweight as
+ * declaring a local `char buf[512]`.
+ *
+ * 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, AVBPrint.len can be greater than AVBPrint.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
+ * av_bprint_is_complete().
+ *
+ * The AVBPrint.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).

+ * 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.

+ * AVChannelLayout carries only the channel count).

+ * public ABI and may be used by the caller. E.g. it may be allocated on stack
+ * or embedded in caller-defined structs.
+ *
+ * AVChannelLayout can be initialized as follows:
+ * - default initialization with {0}, followed by setting all used fields
+ * correctly;
+ * - by assigning one of the predefined AV_CHANNEL_LAYOUT_* initializers;
+ * - with a constructor function, such as av_channel_layout_default(),
+ * av_channel_layout_from_mask() or av_channel_layout_from_string().
+ *
+ * The channel layout must be unitialized with av_channel_layout_uninit()

+ * av_channel_layout_copy() must be used instead (and its return value should

+ * should be applied to video frames for correct presentation. It is compatible
+ * with the matrices stored in the ISO/IEC 14496-12 container format.
+ *
+ * The data is a 3x3 matrix represented as a 9-element array:
+ *
+ * @code{.unparsed}
+ * | a b u |
+ * (a, b, u, c, d, v, x, y, w) -> | c d v |
+ * | x y w |
+ * @endcode
+ *
+ * All numbers are stored in native endianness, as 16.16 fixed-point values,
+ * except for u, v and w, which are stored as 2.30 fixed-point values.
+ *
+ * The transformation maps a point (p, q) in the source (pre-transformation)
+ * frame to the point (p', q') in the destination (post-transformation) frame as
+ * follows:
+ *
+ * @code{.unparsed}
+ * | a b u |
+ * (p, q, 1) . | c d v | = z * (p', q', 1)
+ * | x y w |
+ * @endcode
+ *
+ * The transformation can also be more explicitly written in components as
+ * follows:
+ *
+ * @code{.unparsed}
+ * p' = (a * p + c * q + x) / z;
+ * q' = (b * p + d * q + y) / z;
+ * z = u * p + v * q + w
+ * @endcode
+ *

+ * Hash functions useful in multimedia.
+ *
+ * Hash functions are widely used in multimedia, from error checking and
+ * concealment to internal regression testing. libavutil has efficient
+ * implementations of a variety of hash functions that may be useful for
+ * FFmpeg and other multimedia applications.
+ *
+ * @{
+ *
+ * @defgroup lavu_hash_generic Generic Hashing API
+ * An abstraction layer for all hash functions supported by libavutil.
+ *
+ * If your application needs to support a wide range of different hash
+ * functions, then the Generic Hashing API is for you. It provides a generic,
+ * reusable API for @ref lavu_hash "all hash functions" implemented in libavutil.
+ * If you just need to use one particular hash function, use the @ref lavu_hash
+ * "individual hash" directly.
+ *
+ * @section Sample Code
+ *
+ * A basic template for using the Generic Hashing API follows:
+ *
+ * @code
+ * struct AVHashContext *ctx = NULL;
+ * const char *hash_name = NULL;
+ * uint8_t *output_buf = NULL;
+ *
+ * // Select from a string returned by av_hash_names()
+ * hash_name = ...;
+ *
+ * // Allocate a hash context
+ * ret = av_hash_alloc(&ctx, hash_name);
+ * if (ret < 0)
+ * return ret;
+ *
+ * // Initialize the hash context
+ * av_hash_init(ctx);
+ *
+ * // Update the hash context with data
+ * while (data_left) {
+ * av_hash_update(ctx, data, size);
+ * }
+ *
+ * // Now we have no more data, so it is time to finalize the hash and get the
+ * // output. But we need to first allocate an output buffer. Note that you can
+ * // use any memory allocation function, including malloc(), not just
+ * // av_malloc().
+ * output_buf = av_malloc(av_hash_get_size(ctx));
+ * if (!output_buf)
+ * return AVERROR(ENOMEM);
+ *
+ * // Finalize the hash context.
+ * // You can use any of the av_hash_final*() functions provided, for other
+ * // output formats. If you do so, be sure to adjust the memory allocation
+ * // above. See the function documentation below for the exact amount of extra
+ * // memory needed.
+ * av_hash_final(ctx, output_buffer);
+ *
+ * // Free the context
+ * av_hash_freep(&ctx);
+ * @endcode
+ *
+ * @section Hash Function-Specific Information
+ * If the CRC32 hash is selected, the #AV_CRC_32_IEEE polynomial will be
+ * used.
+ *
+ * If the Murmur3 hash is selected, the default seed will be used. See @ref
+ * lavu_murmur3_seedinfo "Murmur3" for more information.
+ *
+ * @{

+ *
+ * libavutil supports two systems of appending elements onto a dynamically
+ * allocated array, the first one storing the pointer to the value in 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

+ * - 128-bit output for 64-bit platforms
+ *
+ * FFmpeg only implements the last variant: 128-bit output designed for 64-bit

+ *

+ * By design, MurmurHash3 requires a seed to operate. In response to this,

+ * as the seed, and therefore does not (av_murmur3_init()).

+/**
+ * @defgroup avoptions AVOptions
+ * @ingroup lavu_data
+ * @{
+ * AVOptions provide a generic system to declare options on arbitrary structs
+ * ("objects"). An option can have a help text, a type and a range of possible
+ * values. Options may then be enumerated, read and written to.
+ *
+ * There are two modes of access to members of AVOption and its child structs.
+ * One is called 'native access', and refers to access from the code that
+ * declares the AVOption in question. The other is 'foreign access', and refers
+ * to access from other code.
+ *
+ * Certain struct members in this header are documented as 'native access only'
+ * or similar - it means that only the code that declared the AVOption in
+ * question is allowed to access the field. This allows us to extend the
+ * semantics of those fields without breaking API compatibility.
+ *
+ * @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_iterate() 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_iterate(void **iter)
+ * {
+ * const AVClass *c = *iter ? NULL : &child_class;
+ * *iter = (void*)(uintptr_t)c;
+ * return c;
+ * }
+ * @endcode
+ * Putting child_next() and child_class_iterate() 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_iterate() are needed. The distinction is that child_next()
+ * iterates over actually existing objects, while child_class_iterate()
+ * 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_iterate() 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_iterate() 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.

+ * environments where everything is done by the book. It has the shortcoming
+ * of assuming that input PNG data with no gamma information is linear - this
+ * is unlikely to be correct unless the PNG files where generated locally.
+ * Most of the time the output precision will be so low as to show
+ * significant banding in dark areas of the image.
+ *
+ * png_set_expand_16(pp);
+ * png_set_alpha_mode(pp, PNG_ALPHA_STANDARD, PNG_DEFAULT_sRGB);
+ * This is a somewhat more realistic Jim Blinn inspired approach. PNG files
+ * are assumed to have the sRGB encoding if not marked with a gamma value and
+ * the output is always 16 bits per component. This permits accurate scaling
+ * and processing of the data. If you know that your input PNG files were
+ * generated locally you might need to replace PNG_DEFAULT_sRGB with the
+ * correct value for your system.
+ *
+ * png_set_alpha_mode(pp, PNG_ALPHA_OPTIMIZED, PNG_DEFAULT_sRGB);
+ * If you just need to composite the PNG image onto an existing background
+ * and if you control the code that does this you can use the optimization
+ * setting. In this case you just copy completely opaque pixels to the
+ * output. For pixels that are not completely transparent (you just skip
+ * those) you do the composition math using png_composite or png_composite_16
+ * below then encode the resultant 8-bit or 16-bit values to match the output
+ * encoding.
+ *
+ * Other cases
+ * If neither the PNG nor the standard linear encoding work for you because
+ * of the software or hardware you use then you have a big problem. The PNG
+ * case will probably result in halos around the image. The linear encoding
+ * will probably result in a washed out, too bright, image (it's actually too
+ * contrasty.) Try the ALPHA_OPTIMIZED mode above - this will probably
+ * substantially reduce the halos. Alternatively try:
+ *
+ * png_set_alpha_mode(pp, PNG_ALPHA_BROKEN, PNG_DEFAULT_sRGB);
+ * This option will also reduce the halos, but there will be slight dark
+ * halos round the opaque parts of the image where the background is light.
+ * In the OPTIMIZED mode the halos will be light halos where the background
+ * is dark. Take your pick - the halos are unavoidable unless you can get
+ * your hardware/software fixed! (The OPTIMIZED approach is slightly
+ * faster.)
+ *
+ * When the default gamma of PNG files doesn't match the output gamma.
+ * If you have PNG files with no gamma information png_set_alpha_mode allows
+ * you to provide a default gamma, but it also sets the output gamma to the
+ * matching value. If you know your PNG files have a gamma that doesn't
+ * match the output you can take advantage of the fact that
+ * png_set_alpha_mode always sets the output gamma but only sets the PNG
+ * default if it is not already set:
+ *
+ * png_set_alpha_mode(pp, PNG_ALPHA_PNG, PNG_DEFAULT_sRGB);
+ * png_set_alpha_mode(pp, PNG_ALPHA_PNG, PNG_GAMMA_MAC);
+ * The first call sets both the default and the output gamma values, the
+ * second call overrides the output gamma without changing the default. This
+ * is easier than achieving the same effect with png_set_gamma. You must use
+ * PNG_ALPHA_PNG for the first call - internal checking in png_set_alpha will
+ * fire if more than one call to png_set_alpha_mode and png_set_background is
+ * made in the same read operation, however multiple calls with PNG_ALPHA_PNG
+ * are ignored.

+/* Provide the default handling for all unknown chunks or, optionally, for
+ * specific unknown chunks.
+ *
+ * NOTE: prior to 1.6.0 the handling specified for particular chunks on read was
+ * ignored and the default was used, the per-chunk setting only had an effect on
+ * write. If you wish to have chunk-specific handling on read in code that must
+ * work on earlier versions you must use a user chunk callback to specify the
+ * desired handling (keep or discard.)
+ *
+ * The 'keep' parameter is a PNG_HANDLE_CHUNK_ value as listed below. The
+ * parameter is interpreted as follows:
+ *
+ * READ:
+ * PNG_HANDLE_CHUNK_AS_DEFAULT:
+ * Known chunks: do normal libpng processing, do not keep the chunk (but
+ * see the comments below about PNG_HANDLE_AS_UNKNOWN_SUPPORTED)
+ * Unknown chunks: for a specific chunk use the global default, when used
+ * as the default discard the chunk data.
+ * PNG_HANDLE_CHUNK_NEVER:
+ * Discard the chunk data.
+ * PNG_HANDLE_CHUNK_IF_SAFE:
+ * Keep the chunk data if the chunk is not critical else raise a chunk
+ * error.
+ * PNG_HANDLE_CHUNK_ALWAYS:
+ * Keep the chunk data.
+ *
+ * If the chunk data is saved it can be retrieved using png_get_unknown_chunks,
+ * below. Notice that specifying "AS_DEFAULT" as a global default is equivalent
+ * to specifying "NEVER", however when "AS_DEFAULT" is used for specific chunks
+ * it simply resets the behavior to the libpng default.
+ *
+ * INTERACTION WITH USER CHUNK CALLBACKS:
+ * The per-chunk handling is always used when there is a png_user_chunk_ptr
+ * callback and the callback returns 0; the chunk is then always stored *unless*
+ * it is critical and the per-chunk setting is other than ALWAYS. Notice that
+ * the global default is *not* used in this case. (In effect the per-chunk
+ * value is incremented to at least IF_SAFE.)
+ *
+ * IMPORTANT NOTE: this behavior will change in libpng 1.7 - the global and
+ * per-chunk defaults will be honored. If you want to preserve the current
+ * behavior when your callback returns 0 you must set PNG_HANDLE_CHUNK_IF_SAFE
+ * as the default - if you don't do this libpng 1.6 will issue a warning.
+ *
+ * If you want unhandled unknown chunks to be discarded in libpng 1.6 and
+ * earlier simply return '1' (handled).
+ *
+ * PNG_HANDLE_AS_UNKNOWN_SUPPORTED:
+ * If this is *not* set known chunks will always be handled by libpng and
+ * will never be stored in the unknown chunk list. Known chunks listed to
+ * png_set_keep_unknown_chunks will have no effect. If it is set then known
+ * chunks listed with a keep other than AS_DEFAULT will *never* be processed
+ * by libpng, in addition critical chunks must either be processed by the
+ * callback or saved.
+ *
+ * The IHDR and IEND chunks must not be listed. Because this turns off the
+ * default handling for chunks that would otherwise be recognized the
+ * behavior of libpng transformations may well become incorrect!
+ *
+ * WRITE:
+ * When writing chunks the options only apply to the chunks specified by
+ * png_set_unknown_chunks (below), libpng will *always* write known chunks
+ * required by png_set_ calls and will always write the core critical chunks
+ * (as required for PLTE).
+ *
+ * Each chunk in the png_set_unknown_chunks list is looked up in the
+ * png_set_keep_unknown_chunks list to find the keep setting, this is then
+ * interpreted as follows:
+ *
+ * PNG_HANDLE_CHUNK_AS_DEFAULT:
+ * Write safe-to-copy chunks and write other chunks if the global
+ * default is set to _ALWAYS, otherwise don't write this chunk.
+ * PNG_HANDLE_CHUNK_NEVER:
+ * Do not write the chunk.
+ * PNG_HANDLE_CHUNK_IF_SAFE:
+ * Write the chunk if it is safe-to-copy, otherwise do not write it.
+ * PNG_HANDLE_CHUNK_ALWAYS:
+ * Write the chunk.
+ *
+ * Note that the default behavior is effectively the opposite of the read case -
+ * in read unknown chunks are not stored by default, in write they are written
+ * by default. Also the behavior of PNG_HANDLE_CHUNK_IF_SAFE is very different
+ * - on write the safe-to-copy bit is checked, on read the critical bit is
+ * checked and on read if the chunk is critical an error will be raised.
+ *
+ * num_chunks:
+ * ===========
+ * If num_chunks is positive, then the "keep" parameter specifies the manner
+ * for handling only those chunks appearing in the chunk_list array,
+ * otherwise the chunk list array is ignored.
+ *
+ * If num_chunks is 0 the "keep" parameter specifies the default behavior for
+ * unknown chunks, as described above.
+ *
+ * If num_chunks is negative, then the "keep" parameter specifies the manner
+ * for handling all unknown chunks plus all chunks recognized by libpng

+ * Section 5: SIMPLIFIED API
+ *******************************************************************************
+ *
+ * Please read the documentation in libpng-manual.txt (TODO: write said
+ * documentation) if you don't understand what follows.
+ *
+ * The simplified API hides the details of both libpng and the PNG file format
+ * itself. It allows PNG files to be read into a very limited number of
+ * in-memory bitmap formats or to be written from the same formats. If these
+ * formats do not accommodate your needs then you can, and should, use the more
+ * sophisticated APIs above - these support a wide variety of in-memory formats
+ * and a wide variety of sophisticated transformations to those formats as well
+ * as a wide variety of APIs to manipulate ancillary information.
+ *
+ * To read a PNG file using the simplified API:
+ *
+ * 1) Declare a 'png_image' structure (see below) on the stack, set the
+ * version field to PNG_IMAGE_VERSION and the 'opaque' pointer to NULL
+ * (this is REQUIRED, your program may crash if you don't do it.)
+ * 2) Call the appropriate png_image_begin_read... function.
+ * 3) Set the png_image 'format' member to the required sample format.
+ * 4) Allocate a buffer for the image and, if required, the color-map.
+ * 5) Call png_image_finish_read to read the image and, if required, the
+ * color-map into your buffers.
+ *
+ * There are no restrictions on the format of the PNG input itself; all valid
+ * color types, bit depths, and interlace methods are acceptable, and the
+ * input image is transformed as necessary to the requested in-memory format
+ * during the png_image_finish_read() step. The only caveat is that if you
+ * request a color-mapped image from a PNG that is full-color or makes
+ * complex use of an alpha channel the transformation is extremely lossy and the
+ * result may look terrible.
+ *
+ * To write a PNG file using the simplified API:

+ * b) As a value in the range 0..65535, contained in a 2-byte integer. All
+ * channels can be converted to the original value by dividing by 65535; all
+ * channels are linear. Color channels use the RGB encoding (RGB end-points) of
+ * the sRGB specification. This encoding is identified by the

+ * the actual sRGB transfer curve defined in the sRGB specification (see the
+ * article at ) is used, not the gamma=1/2.2
+ * approximation used elsewhere in libpng.
+ *
+ * When an alpha channel is present it is expected to denote pixel coverage
+ * of the color or luminance channels and is returned as an associated alpha
+ * channel: the color/gray channels are scaled (pre-multiplied) by the alpha
+ * value.
+ *
+ * The samples are either contained directly in the image data, between 1 and 8
+ * bytes per pixel according to the encoding, or are held in a color-map indexed
+ * by bytes in the image data. In the case of a color-map the color-map entries

+/* Function calling conventions.
+ * =============================
+ * Normally it is not necessary to specify to the compiler how to call
+ * a function - it just does it - however on x86 systems derived from
+ * Microsoft and Borland C compilers ('IBM PC', 'DOS', 'Windows' systems
+ * and some others) there are multiple ways to call a function and the
+ * default can be changed on the compiler command line. For this reason
+ * libpng specifies the calling convention of every exported function and
+ * every function called via a user supplied function pointer. This is
+ * done in this file by defining the following macros:
+ *
+ * PNGAPI Calling convention for exported functions.
+ * PNGCBAPI Calling convention for user provided (callback) functions.
+ * PNGCAPI Calling convention used by the ANSI-C library (required
+ * for longjmp callbacks and sometimes used internally to
+ * specify the calling convention for zlib).
+ *
+ * These macros should never be overridden. If it is necessary to
+ * change calling convention in a private build this can be done
+ * by setting PNG_API_RULE (which defaults to 0) to one of the values
+ * below to select the correct 'API' variants.
+ *
+ * PNG_API_RULE=0 Use PNGCAPI - the 'C' calling convention - throughout.
+ * This is correct in every known environment.
+ * PNG_API_RULE=1 Use the operating system convention for PNGAPI and
+ * the 'C' calling convention (from PNGCAPI) for
+ * callbacks (PNGCBAPI). This is no longer required
+ * in any known environment - if it has to be used
+ * please post an explanation of the problem to the
+ * libpng mailing list.
+ *
+ * These cases only differ if the operating system does not use the C
+ * calling convention, at present this just means the above cases
+ * (x86 DOS/Windows systems) and, even then, this does not apply to
+ * Cygwin running on those systems.
+ *
+ * Note that the value must be defined in pnglibconf.h so that what
+ * the application uses to call the library matches the conventions
+ * set when building the library.
+ */
+
+/* Symbol export
+ * =============
+ * When building a shared library it is almost always necessary to tell
+ * the compiler which symbols to export. The png.h macro 'PNG_EXPORT'
+ * is used to mark the symbols. On some systems these symbols can be
+ * extracted at link time and need no special processing by the compiler,
+ * on other systems the symbols are flagged by the compiler and just
+ * the declaration requires a special tag applied (unfortunately) in a
+ * compiler dependent way. Some systems can do either.
+ *
+ * A small number of older systems also require a symbol from a DLL to
+ * be flagged to the program that calls it. This is a problem because
+ * we do not know in the header file included by application code that
+ * the symbol will come from a shared library, as opposed to a statically
+ * linked one. For this reason the application must tell us by setting
+ * the magic flag PNG_USE_DLL to turn on the special processing before
+ * it includes png.h.
+ *
+ * Four additional macros are used to make this happen:
+ *
+ * PNG_IMPEXP The magic (if any) to cause a symbol to be exported from
+ * the build or imported if PNG_USE_DLL is set - compiler
+ * and system specific.
+ *
+ * PNG_EXPORT_TYPE(type) A macro that pre or appends PNG_IMPEXP to
+ * 'type', compiler specific.
+ *
+ * PNG_DLL_EXPORT Set to the magic to use during a libpng build to
+ * make a symbol exported from the DLL. Not used in the
+ * public header files; see pngpriv.h for how it is used
+ * in the libpng build.
+ *
+ * PNG_DLL_IMPORT Set to the magic to force the libpng symbols to come
+ * from a DLL - used to define PNG_IMPEXP when
+ * PNG_USE_DLL is set.
+ */
+
+/* System specific discovery.
+ * ==========================
+ * This code is used at build time to find PNG_IMPEXP, the API settings
+ * and PNG_EXPORT_TYPE(), it may also set a macro to indicate the DLL
+ * import processing is possible. On Windows systems it also sets
+ * compiler-specific macros to the values required to change the calling

+ * @{
+ *
+ * Audio resampling, sample format conversion and mixing library.
+ *
+ * Interaction with lswr is done through SwrContext, which is
+ * allocated with swr_alloc() or swr_alloc_set_opts2(). It is opaque, so all parameters
+ * must be set with the @ref avoptions API.
+ *
+ * The first thing you will need to do in order to use lswr is to allocate
+ * SwrContext. This can be done with swr_alloc() or swr_alloc_set_opts2(). If you
+ * are using the former, you must set options through the @ref avoptions API.
+ * The latter function provides the same feature, but it allows you to set some
+ * common options in the same statement.
+ *
+ * For example the following code will setup conversion from planar float sample
+ * format to interleaved signed 16-bit integer, downsampling from 48kHz to
+ * 44.1kHz and downmixing from 5.1 channels to stereo (using the default mixing
+ * matrix). This is using the swr_alloc() function.
+ * @code
+ * SwrContext *swr = swr_alloc();
+ * av_opt_set_channel_layout(swr, "in_channel_layout", AV_CH_LAYOUT_5POINT1, 0);
+ * av_opt_set_channel_layout(swr, "out_channel_layout", AV_CH_LAYOUT_STEREO, 0);
+ * av_opt_set_int(swr, "in_sample_rate", 48000, 0);
+ * av_opt_set_int(swr, "out_sample_rate", 44100, 0);
+ * av_opt_set_sample_fmt(swr, "in_sample_fmt", AV_SAMPLE_FMT_FLTP, 0);
+ * av_opt_set_sample_fmt(swr, "out_sample_fmt", AV_SAMPLE_FMT_S16, 0);
+ * @endcode
+ *
+ * The same job can be done using swr_alloc_set_opts2() as well:
+ * @code
+ * SwrContext *swr = NULL;
+ * int ret = swr_alloc_set_opts2(&swr, // we're allocating a new context
+ * &(AVChannelLayout)AV_CHANNEL_LAYOUT_STEREO, // out_ch_layout
+ * AV_SAMPLE_FMT_S16, // out_sample_fmt
+ * 44100, // out_sample_rate
+ * &(AVChannelLayout)AV_CHANNEL_LAYOUT_5POINT1, // in_ch_layout
+ * AV_SAMPLE_FMT_FLTP, // in_sample_fmt
+ * 48000, // in_sample_rate
+ * 0, // log_offset
+ * NULL); // log_ctx
+ * @endcode
+ *
+ * Once all values have been set, it must be initialized with swr_init(). If
+ * you need to change the conversion parameters, you can change the parameters
+ * using @ref avoptions, as described above in the first example; or by using
+ * swr_alloc_set_opts2(), but with the first argument the allocated context.
+ * You must then call swr_init() again.
+ *
+ * The conversion itself is done by repeatedly calling swr_convert().
+ * Note that the samples may get buffered in swr if you provide insufficient
+ * output space or if sample rate conversion is done, which requires "future"
+ * samples. Samples that do not require future input can be retrieved at any
+ * time by using swr_convert() (in_count can be set to 0).
+ * At the end of conversion the resampling buffer can be flushed by calling
+ * swr_convert() with NULL in and 0 in_count.
+ *
+ * The samples used in the conversion process can be managed with the libavutil
+ * @ref lavu_sampmanip "samples manipulation" API, including av_samples_alloc()
+ * function used in the following example.
+ *
+ * The delay between input and output, can at any time be found by using
+ * swr_get_delay().
+ *
+ * The following code demonstrates the conversion loop assuming the parameters
+ * from above and caller-defined functions get_input() and handle_output():
+ * @code
+ * uint8_t **input;
+ * int in_samples;
+ *
+ * while (get_input(&input, &in_samples)) {
+ * uint8_t *output;
+ * int out_samples = av_rescale_rnd(swr_get_delay(swr, 48000) +
+ * in_samples, 44100, 48000, AV_ROUND_UP);
+ * av_samples_alloc(&output, NULL, 2, out_samples,
+ * AV_SAMPLE_FMT_S16, 0);
+ * out_samples = swr_convert(swr, &output, out_samples,
+ * input, in_samples);
+ * handle_output(output, out_samples);
+ * av_freep(&output);
+ * }
+ * @endcode
+ *
+ * When the conversion is finished, the conversion
+ * context and everything associated with it must be freed with swr_free().
+ * A swr_close() function is also available, but it exists mainly for
+ * compatibility with libavresample, and is not required to be called.
+ *
+ * There will be no memory leak if the data is not completely flushed before
+ * swr_free().
