Extract DVD audio (with chapter breaks)?

mcdermott

Basically what the thread title implies, I'd like a freeware utility that will allow me to pull the audio from an unencrypted VIDEO_TS folder out into individual files for each chapter. Basically a CD-ripper but for DVDs. This specific video's main audio track is LPCM, not AC3 or DTS, if that matters (it's a concert film).

Have you tried Handbrake? I don't know if it has this particular functionality you're describing but it does damn near everything else.

The FAQ says that it can't.

Lifehacker comes through(?) I don't know if it can do anything other than MP3...don't know if that's a problem or not (not on a Windows machine so I can't test it out)

Awesome, I'll give that a shot.

I knew about Handbrake, and that it wouldn't do the trick. I think FFmpegX might have, but I'm not on a Mac now. I'm actually generally handy with these things, this is just something I've never had to do before.

EDIT: No joy. Looks like it just does manual VOB->MP3 conversion, with manual start/stop points. I can already do that with the software I've got. I'll probably just have to do this semi-manually (convert a chapter at a time to a video file, then demux out the audio).

If I had a DVD with LCPM audio I would test a possible solution. MPlayer/MEncoder are already capable of dumping and encoding audio, and you can specify the DVD title and chapters to start and end at. It would just be a matter of wrapping it up into something more convenient to use (both are CLI applications).

Shit, I didn't even think of that. Yeah, I think MPlayer alone is all I need to get it out as .wav files. I'll just have to fiddle with the command line to get it do exactly what I want.

Once I've got .wav files, obviously converting them is trivial.

Sweet, thanks!


EDIT: It's been like four years since I've used MPlayer as an actual command-line program.

Try something like:

mplayer dvd://1 -chapter 2 -vc dummy -vo null -dumpaudio -dumpfile "output.wav"

The integer on the "dvd://<int>" bit is which title to play. Chapter can take two arguments as a range: the first is what chapter to play, the second is which chapter to stop at. The second argument might be inclusive (it isn't specified and I haven't used it in an eternity), so for only one chapter you might need to do "-chapter 3-3".
