Anton Khirnov 50ecba7e84 fftools/ffmpeg: drop an arbitrary condition Encoding init code will currently fall back to a 25fps default when no framerate is known or specified, but only if there is a known source input stream. There is no good reason for this condition, so drop it.		2022-11-23 10:36:23 +01:00

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.
