tcdecode -i foo.mp3 -x mp3
decodes an MPEG audio stream and prints raw PCM data to stdout.
tcextract -i foo.avi -x mp3 | tcdecode -x mp3
extracts an MPEG audio track from the AVI-file foo.avi and pipes
the frames into the decoder
is part of and usually called by transcode.
However, it can also be used independently.
tcdecode reads source (from stdin if not explicitely
defined) and prints on the standard output.
Specify input source. If
ommited, stdin is assumed. tcdecode reads
streams from file or from stdin.
