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 + * Lavf allows to configure 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. + * + * @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 or filename, which + * is passed to avformat_open_input(), as in the following code: + * @code + * const char *url = "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_decode_video2(), avcodec_decode_audio4() 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. + * + * The packet data belongs to the demuxer and is invalid after the next call to + * av_read_frame(). The user must free the packet with av_free_packet() before + * calling av_read_frame() again or closing the file. + * + * @section lavf_decoding_seek Seeking + * @} + * + * @defgroup lavf_encoding Muxing + * @{ + * @} + * + * @defgroup lavf_io I/O Read/Write + * @{ + * @} + * + * @defgroup lavf_codec Demuxers + * @{ + * @defgroup lavf_codec_native Native Demuxers + * @{ + * @} + * @defgroup lavf_codec_wrappers External library wrappers + * @{ + * @} + * @} + * @defgroup lavf_protos I/O Protocols + * @{ + * @} + * @defgroup lavf_internal Internal + * @{ + * @} + * @} + * + */ + +#include +#include /* FILE */ +#include "libavcodec/avcodec.h" +#include "libavutil/dict.h" +#include "libavutil/log.h" + +#include "avio.h" +#include "libavformat/version.h" + +#if FF_API_AV_GETTIME +#include "libavutil/time.h" +#endif + +struct AVFormatContext; + + +/** + * @defgroup metadata_api Public Metadata API + * @{ + * @ingroup libavf + * The metadata API allows libavformat to export metadata tags to a client + * application when demuxing. Conversely it allows a client application to + * set metadata when muxing. + * + * Metadata is exported or set as pairs of key/value strings in the 'metadata' + * fields of the AVFormatContext, AVStream, AVChapter and AVProgram structs + * using the @ref lavu_dict "AVDictionary" API. Like all strings in FFmpeg, + * metadata is assumed to be UTF-8 encoded Unicode. Note that metadata + * exported by demuxers isn't checked to be valid UTF-8 in most cases. + * + * Important concepts to keep in mind: + * - Keys are unique; there can never be 2 tags with the same key. This is + * also meant semantically, i.e., a demuxer should not knowingly produce + * several keys that are literally different but semantically identical. + * E.g., key=Author5, key=Author6. In this example, all authors must be + * placed in the same tag. + * - Metadata is flat, not hierarchical; there are no subtags. If you + * want to store, e.g., the email address of the child of producer Alice + * and actor Bob, that could have key=alice_and_bobs_childs_email_address. + * - Several modifiers can be applied to the tag name. This is done by + * appending a dash character ('-') and the modifier name in the order + * they appear in the list below -- e.g. foo-eng-sort, not foo-sort-eng. + * - language -- a tag whose value is localized for a particular language + * is appended with the ISO 639-2/B 3-letter language code. + * For example: Author-ger=Michael, Author-eng=Mike + * The original/default language is in the unqualified "Author" tag. + * A demuxer should set a default if it sets any translated tag. + * - sorting -- a modified version of a tag that should be used for + * sorting will have '-sort' appended. E.g. artist="The Beatles", + * artist-sort="Beatles, The". + * + * - Demuxers attempt to export metadata in a generic format, however tags + * with no generic equivalents are left as they are stored in the container. + * Follows a list of generic tag names: + * + @verbatim + album -- name of the set this work belongs to + album_artist -- main creator of the set/album, if different from artist. + 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.

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 { + * AVClass *class; + * int int_opt; + * char *str_opt; + * uint8_t *bin_opt; + * int bin_len; + * } test_struct; + * + * static const AVOption 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 = 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_malloc(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 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.
