Anton Khirnov 5939c8d361 lavu/fifo: disallow overly large fifo sizes The API currently allows creating FIFOs up to - UINT_MAX: av_fifo_alloc(), av_fifo_realloc(), av_fifo_grow() - SIZE_MAX: av_fifo_alloc_array() However the usable limit is determined by - rndx/wndx being uint32_t - av_fifo_[size,space] returning int so no FIFO should be larger than the smallest of - INT_MAX - UINT32_MAX - SIZE_MAX (which should be INT_MAX an all commonly used platforms). Return an error on trying to allocate FIFOs larger than this limit.		2022-02-07 00:29:05 +01:00

libavformat implements streaming protocols, container formats and basic I/O access.
libavutil includes hashers, decompressors and miscellaneous utility functions.
libavfilter provides means to alter decoded audio and video through a directed graph of connected filters.
libavdevice provides an abstraction to access capture and playback devices.
libswresample implements audio mixing and resampling routines.
libswscale implements color conversion and scaling routines.

Tools

ffmpeg is a command line toolbox to manipulate, convert and stream multimedia content.
ffplay is a minimalistic multimedia player.
ffprobe is a simple analysis tool to inspect multimedia content.
Additional small tools such as aviocat, ismindex and qt-faststart.
