Indeed it fixes the problem (well increasing cache triggers the no sound
after seek bug).

I also noticed that we often get audio frames before some B-pictures
with a lower pts and as there is no track discrimination when the demux
call ES_OUT_SET_PCR, the B-frames will be sent with a pts lower than the
So I tried to send ES_OUT_SET_PCR only for the video track and the bug
seems to disappear.
