Some containers (e.g. large VOBs) are not easily probed and require
additional options for avprobe/ffprobe to find audio streams. We do
this by looping and increasing the duration/size of the probe to
find new audio streams.
This seems to work reasonably well for some DVD rips I have until
seeking is required. This breaks if the seek point (including seeks
for source effects) exceeds the avprobe/ffprobe -analyzeduration.
Anyways, I recommend extracting the audio stream (without
transcoding) out of the VOB container as the best way to go.
Something like:
avconv -analyzeduration 2G -probesize 2G \
-i input.vob -vn -sn -c:a copy -map 0:$STREAM_NR output.ext
