Hi there,

Just encountered a good example of this problem hitting me. My machine
is a Archlinux 3.6.6 i7-2620M CPU @ 2.70GHz with 4G of RAM, so I can't
see the machine being too slow.

The huge recorded mkv file exhibits the problem when playing back with
ffplay. Then transcoded {mp4,webm} also show the video playing too
fast with the audio being out of sync:

The log file is here:

Can anyone advise what I might be doing wrong?

Kind regards,
