▼Data Structures
AVBuffer	AVBuffer is an API for reference-counted data buffers
AVBufferPool	AVBufferPool is an API for a lock-free thread-safe pool of AVBuffers
▼AVOptions	AVOptions provide a generic system to declare options on arbitrary structs ("objects")
Evaluating option strings	This group of functions can be used to evaluate option strings and get numbers out of them
Option setting functions	Those functions set the field of obj with the given name to value
Option getting functions	Those functions get a value of the option with the given name from an object
AVDictionary	Simple key:value store
AVTree	Low complexity tree container
▼Audio related

▼Other
Internal	Not exported functions, for internal usage only
▼Constants
Encoding specific
Timestamp specific	FFmpeg internal timebase and timestamp definitions
Image related	AVPicture types, pixel formats and basic image planes manipulation
Version and Build diagnostics	Macros and function useful to check at compiletime and at runtime which version of libavutil is in use
Media Type	Media Type
Preprocessor String Macros	String manipulation macros
Library Version Macros	Useful to check and match library version in order to maintain backward compatibility
Deprecation guards	FF_API_* defines may be placed below to indicate public API that will be dropped at a future version bump
Libpostproc
Libswresample	Libswresample (lswr) is a library that handles audio resampling, sample format conversion and mixing
