Can ffmpeg identify which audio and video codecs are used in a given
file? Is there a way to 'ask' it whether an MP4 has sound encoded in
aac. mp3, speex etc?
It just seems awkward that I have to play the video in VLC to find out
its format, just to find the file extension I should give the output
file when I use ffmpeg to extract it.
