transcode replacement to rip audio from video dvd

[hobbes@poukram.net]

Hello,

in the past I used a nice little script to rip the audio part of video
dvds (mostly concerts) to mp3 files.

That script used the tool transcode, here is the main line:

for i in {1..$NUM}; do transcode -x null,dvd -y null,tcaud -i $DEVICE -T $TITLE,$i,$ANGLE -a $AUDIO --lame_preset standard -E 44100,16,2 -m $NOM$i.mp3; done

So it ripped the audio part of each chapter of the main title, and
converted it to mp3 files.

But transcode has been removed from debian because «replacements exist»:

https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=817199

I have searched a lot, but I can't find a tool to just rip the audio
part of dvd chapters. ffmpeg is more than capable to do the encoding
part, but it lacks dvd ripping capabilities. HandbrakeCli could be a
contender, but it absolutely wants to rip and encode video, which in my
case is a waste of ressources.

Any idea ?

Thanks,
