* @section ffmpeg_intro Introduction
*
* 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 lavd "libavdevice" special devices muxing/demuxing library
* @li @ref lavu "libavutil" common utility library
* @li @ref lswr "libswresample" audio resampling, format conversion and mixing
* @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
* <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.

* Buffer to print data progressively

* encoding-agnostic and can even hold binary data.
*
* Small buffers are kept in the structure itself, and thus require no

* length.
*
* In other words, buf->len can be greater than buf->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

*
* The 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).

*
* @{
* 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).

*
* 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
