Hello,

I am trying to extract an audio track from vob files. At first I
recognized an async between audio and the correspondig video track of
about 0.5-1 sec. Later I figured out, that the beginning of the AC3
track was missing and therefore the track started too early which led to
the async.
I tried several different parameters including "-M 2" but nothing
helped, the first 0.5-1 seconds were always missing.

The complete command was:
transcode -a 3 -x null,vob -y null,raw -A -n 0x2000 -N 0x2000 -o
track3.ac3 -i myvobfiles/

I hope someone can help me. Could this be a bug?

---

Another thing I found out is that the AC3 file using -m was different
when I did a video extraction at the same time (but with the same audio
parameters). Any explanations to this behavior?


Thanks,
Stefan
