Overview
lav2wav can be used to extract the audio to stdout. This output goes to stdout and can be saved as a wav file or piped to another sound processing tool that is able to handle the wav format. This can be mp2enc and toolame for mpeg layer 2 audio, or for example lame for mpeg layer 3 audio.
The input files may be any combination of AVI (.avi), Quicktime (.qt) or editlist files so long as they are all lavtools- readable (e.g. MJPEG-encoded AVI/Quicktime or DV type 2 AVI).
