I want to make a CD using the audio tracks of some video clips. I was thinking of using
avconv to convert the files. As far as the other steps go, I found some instructions on the Arch Wiki. This is the command that gets used:
for i in *.mp3; do mpg123 --rate 44100 --stereo --buffer 3072 --resync -w `basename $i .mp3`.wav $i; done
Obviously I am not dealing with mp3 files, so I need the
avconv equivalent of the above one-liner for dealing with mp4 and flv files. I can provide additional information about the files' bitrates and such if necessary.
