A complete, cross-platform solution to record, convert and stream audio and video.
FFmpeg is the leading multimedia framework, able to decode, encode, transcode, mux, demux, stream, filter and play pretty much anything that humans and machines have created. It supports the most obscure ancient formats up to the cutting edge. No matter if they were designed by some standards committee, the community or a corporation.
It contains libavcodec, libavutil, libavformat, libavfilter, libavdevice, libswscale and libswresample which can be used by applications. As well as ffmpeg, ffplay and ffprobe which can be used by end users for transcoding and playing.
libavutil is a library containing functions for simplifying programming, including random number generators, data structures, mathematics routines, core multimedia utilities, and much more.
libavcodec is a library containing decoders and encoders for audio/video codecs.
libavformat is a library containing demuxers and muxers for multimedia container formats.
libavdevice is a library containing input and output devices for grabbing from and rendering to many common multimedia input/output software frameworks, including Video4Linux, Video4Linux2, VfW, and ALSA.
libavfilter is a library containing media filters.
libswscale is a library performing highly optimized image scaling and color space/pixel format conversion operations.
libswresample is a library performing highly optimized audio resampling, rematrixing and sample format conversion operations.
