* 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 lsws "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
* <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.

* allocation fails, data stop being appended to the buffer, but the length

* 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).

* 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.

* @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.
*
* @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.
