VOB to audio finishes instantly, zero-KB output file

[celticwhisper]

I'm trying to extract a sound clip from a DVD I have , so I can use it as my PC's error sound. I ripped the DVD with Mac The Ripper and loaded the resulting VOB file into FFmpegX. I selected "movie audio to mp3" and set my target bitrate to 256Kbit/sec. Sampling is 48000, 2 channels, CBR mode.

The DVD has multiple language tracks, one Japanese and one English.

When I finally click "Encode" after configuring my settings the way I want them, I end up with an encoding process that finishes almost instantaneously and a zero-KB output file.

I can get this to work okay, sometimes (seemingly at random) on the Japanese audio track, but I have yet to make it work on the English track. The stream is useless to me until I can get English output.

Anyone else have this problem and know how to get around it?

P.S. If there's another way to go about extracting audio from a VOB file that simply doesn't use FFmpegX at all, I'm open to those suggestions as well.

Okay, I finally made it work.

I had to demux the VOB file, then relaunch FFmpegX, import the resulting .ac3 file for the English track, select "Audio file to mp3," and finally open it in Audacity to extract my clip.

There's GOT to be a more straightforward way than this to do it. And why does FFmpegX refuse to encode more than one file at a time per launch? Closing and relaunching doesn't seem a terribly intuitive process.

• DVD to MP3 Audio
• How do I capture audio snippet from DVD for use on a CD?

Must be a local thing.
