*
|
||||
* Each of the FFmpeg libraries contains a version.h header, which defines a
|
||||
* major, minor and micro version number with the
|
||||
* <em>LIBRARYNAME_VERSION_{MAJOR,MINOR,MICRO}</em> 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.

|
||||
// * 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).

* Use av_dict_get() to retrieve an entry or iterate over all

* AVFrame must be freed with av_frame_free().

* The data described by an AVFrame is usually reference counted through the

* AVBuffer API. The underlying buffer references are stored in AVFrame.buf /
|

* AVFrame.extended_buf. An AVFrame is considered to be reference counted if at
|
||||
* least one reference is set, i.e. if AVFrame.buf[0] != NULL. In such a case,

* every single data plane must be contained in one of the buffers in

* sizeof(AVFrame) is not a part of the public ABI, so new fields may be added

* to the end with a minor bump.

||||
* Similarly fields that are marked as to be only accessed by
|
||||
* av_opt_ptr() can be reordered. This allows 2 forks to add fields

|
||||
// * @{
|
||||
// * 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.
|
||||
// *
|
||||
// * @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 {
|
||||
// * 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_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 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 allows 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.

* image data is stored in AVFrame.data[0]. The palette is transported in
|

* AVFrame.data[1], is 1024 bytes long (256 4-byte entries) and is
|
||||
* formatted the same as in AV_PIX_FMT_RGB32 described above (i.e., it is
|
||||
* also endian-specific). Note also that the individual RGB palette
|
||||
* components stored in AVFrame.data[1] should be in the range 0..255.
|
||||
* This is important as many custom PAL8 video codecs that were designed
|

* allocating the picture.

* Make sure that all newly added big-endian formats have (pix_fmt & 1) == 1

|

* @{
|
||||
*
|
||||
* Libswresample (lswr) is a library that handles audio resampling, sample
|
||||
* format conversion and mixing.
|
||||
*
|
||||
* Interaction with lswr is done through SwrContext, which is
|
||||
* allocated with swr_alloc() or swr_alloc_set_opts(). It is opaque, so all parameters
|
||||
* must be set with the @ref avoptions API.
|
||||
*
|
||||
* 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):
|
||||
* @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
|
||||
*
|
||||
* 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
|
||||
* as described above, or by using swr_alloc_set_opts(), 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 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().
|
||||
* There will be no memory leak if the data is not completely flushed before
|
||||
* swr_free().
