(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. - * - * 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. 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. - * 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. - * @} - */ - -/** - * @defgroup lavc_core Core functions/structures. -

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

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

An option can have a help text, a type and a range of possible - * values. Options may then be enumerated, read and written to. - * - * @section avoptions_implement Implementing AVOptions - * This section describes how to add AVOptions capabilities to a struct. - * - * All AVOptions-related information is stored in an AVClass. Therefore - * the first member of the struct should be a pointer to an AVClass describing it. - * The option field of the AVClass must be set to a NULL-terminated static array - * of AVOptions.

It must - * also declare an offset in bytes from the start of the struct, where the field - * associated with this AVOption is located. Other fields in the AVOption struct - * should also be set when applicable, but are not required. - * - * The following example illustrates an AVOptions-enabled struct: - * @code - * typedef struct test_struct { - * const AVClass *class; - * int int_opt; - * char *str_opt; - * uint8_t *bin_opt; - * int bin_len; - * } test_struct; - * - * static const AVOption test_options[] = { - * { "test_int", "This is a test option of int type.", offsetof(test_struct, int_opt), - * AV_OPT_TYPE_INT, { .i64 = -1 }, INT_MIN, INT_MAX }, - * { "test_str", "This is a test option of string type.", offsetof(test_struct, str_opt), - * AV_OPT_TYPE_STRING }, - * { "test_bin", "This is a test option of binary type.", offsetof(test_struct, bin_opt), - * AV_OPT_TYPE_BINARY }, - * { NULL }, - * }; - * - * static const AVClass test_class = { - * .class_name = "test class", - * .item_name = av_default_item_name, - * .option = test_options, - * .version = LIBAVUTIL_VERSION_INT, - * }; - * @endcode - * - * Next, when allocating your struct, you must ensure that the AVClass pointer - * is set to the correct value. Then, av_opt_set_defaults() can be called to - * initialize defaults. After that the struct is ready to be used with the - * AVOptions API. - * - * When cleaning up, you may use the av_opt_free() function to automatically - * free all the allocated string and binary options. - * - * Continuing with the above example: - * - * @code - * test_struct *alloc_test_struct(void) - * { - * test_struct *ret = av_mallocz(sizeof(*ret)); - * ret->class = &test_class; - * av_opt_set_defaults(ret); - * return ret; - * } - * void free_test_struct(test_struct **foo) - * { - * av_opt_free(*foo); - * av_freep(foo); - * } - * @endcode - * - * @subsection avoptions_implement_nesting Nesting - * It may happen that an AVOptions-enabled struct contains another - * AVOptions-enabled struct as a member (e.g. AVCodecContext in - * libavcodec exports generic options, while its priv_data field exports - * codec-specific options). In such a case, it is possible to set up the - * parent struct to export a child's options. To do that, simply - * implement AVClass.child_next() and AVClass.child_class_next() in the - * parent struct's AVClass. - * Assuming that the test_struct from above now also contains a - * child_struct field: - * - * @code - * typedef struct child_struct { - * AVClass *class; - * int flags_opt; - * } child_struct; - * static const AVOption child_opts[] = { - * { "test_flags", "This is a test option of flags type.", - * offsetof(child_struct, flags_opt), AV_OPT_TYPE_FLAGS, { .i64 = 0 }, INT_MIN, INT_MAX }, - * { NULL }, - * }; - * static const AVClass child_class = { - * .class_name = "child class", - * .item_name = av_default_item_name, - * .option = child_opts, - * .version = LIBAVUTIL_VERSION_INT, - * }; - * - * void *child_next(void *obj, void *prev) - * { - * test_struct *t = obj; - * if (!prev && t->child_struct) - * return t->child_struct; - * return NULL - * } - * const AVClass child_class_next(const AVClass *prev) - * { - * return prev ? NULL : &child_class; - * } - * @endcode - * Putting child_next() and child_class_next() as defined above into - * test_class will now make child_struct's options accessible through - * test_struct (again, proper setup as described above needs to be done on - * child_struct right after it is created). - * - * From the above example it might not be clear why both child_next() - * and child_class_next() are needed. The distinction is that child_next() - * iterates over actually existing objects, while child_class_next() - * iterates over all possible child classes. E.g. if an AVCodecContext - * was initialized to use a codec which has private options, then its - * child_next() will return AVCodecContext.priv_data and finish - * iterating. OTOH child_class_next() on AVCodecContext.av_class will - * iterate over all available codecs with private options. - * - * @subsection avoptions_implement_named_constants Named constants - * It is possible to create named constants for options. Simply set the unit - * field of the option the constants should apply to a string and - * create the constants themselves as options of type AV_OPT_TYPE_CONST - * with their unit field set to the same string. - * Their default_val field should contain the value of the named - * constant. - * For example, to add some named constants for the test_flags option - * above, put the following into the child_opts array: - * @code - * { "test_flags", "This is a test option of flags type.", - * offsetof(child_struct, flags_opt), AV_OPT_TYPE_FLAGS, { .i64 = 0 }, INT_MIN, INT_MAX, "test_unit" }, - * { "flag1", "This is a flag with value 16", 0, AV_OPT_TYPE_CONST, { .i64 = 16 }, 0, 0, "test_unit" }, - * @endcode - * - * @section avoptions_use Using AVOptions - * This section deals with accessing options in an AVOptions-enabled struct. - * Such structs in FFmpeg are e.g. AVCodecContext in libavcodec or - * AVFormatContext in libavformat. - * - * @subsection avoptions_use_examine Examining AVOptions - * The basic functions for examining options are av_opt_next(), which iterates - * over all options defined for one object, and av_opt_find(), which searches - * for an option with the given name. - * - * The situation is more complicated with nesting. An AVOptions-enabled struct - * may have AVOptions-enabled children. Passing the AV_OPT_SEARCH_CHILDREN flag - * to av_opt_find() will make the function search children recursively. - * - * For enumerating there are basically two cases. The first is when you want to - * get all options that may potentially exist on the struct and its children - * (e.g. when constructing documentation). In that case you should call - * av_opt_child_class_next() recursively on the parent struct's AVClass. The - * second case is when you have an already initialized struct with all its - * children and you want to get all options that can be actually written or read - * from it. In that case you should call av_opt_child_next() recursively (and - * av_opt_next() on each result). - * - * @subsection avoptions_use_get_set Reading and writing AVOptions - * When setting options, you often have a string read directly from the - * user. In such a case, simply passing it to av_opt_set() is enough. For - * non-string type options, av_opt_set() will parse the string according to the - * option type. - * - * Similarly av_opt_get() will read any option type and convert it to a string - * which will be returned. Do not forget that the string is allocated, so you - * have to free it with av_free(). - * - * In some cases it may be more convenient to put all options into an - * AVDictionary and call av_opt_set_dict() on it. A specific case of this - * are the format/codec open functions in lavf/lavc which take a dictionary - * filled with option as a parameter. This makes it possible to set some options - * that cannot be set otherwise, since e.g. the input file format is not known - * before the file is actually opened. - */ - -enum AVOptionType{ - AV_OPT_TYPE_FLAGS, - AV_OPT_TYPE_INT, - AV_OPT_TYPE_INT64, - AV_OPT_TYPE_DOUBLE, - AV_OPT_TYPE_FLOAT, - AV_OPT_TYPE_STRING, - AV_OPT_TYPE_RATIONAL, - AV_OPT_TYPE_BINARY, ///< offset must point to a pointer immediately followed by an int for the length - AV_OPT_TYPE_DICT, - AV_OPT_TYPE_CONST = 128, - AV_OPT_TYPE_IMAGE_SIZE = MKBETAG('S','I','Z','E'), ///< offset must point to two consecutive integers - AV_OPT_TYPE_PIXEL_FMT = MKBETAG('P','F','M','T'), - AV_OPT_TYPE_SAMPLE_FMT = MKBETAG('S','F','M','T'), - AV_OPT_TYPE_VIDEO_RATE = MKBETAG('V','R','A','T'), ///< offset must point to AVRational - AV_OPT_TYPE_DURATION = MKBETAG('D','U','R',' '), - AV_OPT_TYPE_COLOR = MKBETAG('C','O','L','R'), - AV_OPT_TYPE_CHANNEL_LAYOUT = MKBETAG('C','H','L','A'), - AV_OPT_TYPE_BOOL = MKBETAG('B','O','O','L'), -}; - -/** - * AVOption - */ -typedef struct AVOption { - const char *name; - - /** - * short English help text - * @todo What about other languages? - */ - const char *help; - - /** - * The offset relative to the context structure where the option - * value is stored.
