I wouldn't say the problem is in dvdemux. It is doing what's expected (that is
take the incoming timestamp and forwarding it on the downstream buffer).

This is a more generic problem regarding jitter in audio streams (try
transcoding an asf audio file to vorbis and you'll most likely encounter the
same issue).

A more 'proper' fix, would be to correct that jitter. That is to see if the
incoming timestamp is within a certain 'diff' of the expected next_ts, and if
so adjust to use next_ts instead of the incoming timestamp.

fwiw, next_ts should also be current_ts + 1/fps (and not the current code).


(/me mumbles at dvdemux code needing some loving in general)
