How to rip AVI from VOB using ffmpeg
10,708
Solution 1
This is what worked:
ffmpeg -i VTS_01_2.VOB -ss 589 -t 274 -c:v mpeg4 -qscale:v 2 -c:a mp2 -b:a 320k output.avi
Apparently, specifying the audio codec is what did the trick.
sameq
should not be used, and it's better to specify the video codec and quality explicitly, too.
Solution 2
Or you can use handbrake. It wraps ffmpeg and does the heavy lifting for you. It comes with a CLI version and has built-in presets for the most common output formats.

I am trying to convert a VOB to an AVI. I have ripped an AVI from this VOB before using ffmpeg, but for some reason it's not working this time. This is what I tried:
ffmpeg -sameq -acodec copy -i VTS_01_2.VOB output.avi
This is the output I get:
