Hi,

I am trying to make an .avi from an .vob file. I made the .vob file with dvd-slideshow, I did not add any music so dvd-slideshow just added a silent audio stream. When I try to convert with ffmpeg, using simply
Code:
ffmpeg -i GBRtest.vob GBRtest.avi
I get this error:

As the stream giving me problems is the audio stream, I tried adding information about the audio stream, like this:
Code:
ffmpeg -i GBRtest.vob GBRtest.avi -ab 192k -acodec ac3 -ar 48000 -ac 6
so I told ffmpeg what the audio bitrate, codec, sampling rate and number of channels are, but I still get the same error:

Any ideas on how to try to get this working?
