ffmpeg is a hyper fast realtime audio/video encoder, a streaming server
and a generic audio and video file converter.

It can grab from a standard Video4Linux video source and convert it into
several file formats based on DCT/motion compensation encoding. Sound is
compressed in MPEG audio layer 2 or using an AC3 compatible stream.

Install libffmpeg if you want to encode multimedia streams.
