34 | <application>FFmpeg</application> is a solution to record, convert and

35 | stream audio and video. It is a very fast video and audio converter and it
|

36 | can also acquire from a live audio/video source. Designed to be intuitive,
|
---|
37 | the command-line interface (<command>ffmpeg</command>) tries to figure out
|

38 | all the parameters, when possible. <application>FFmpeg</application> can
|

39 | also convert from any sample rate to any other, and resize video on the

40 | fly with a high quality polyphase filter.
|

41 | <application>FFmpeg</application> can use a Video4Linux compatible video
|

42 | source and any Open Sound System audio source.
