Combining dv1394src ! dvdemux ! dvdec ! vorvbisenc produces streams with
cracking audio. This issue has been reported by many users in flumotion and can
be confirmed by zaheer.

The timestamps of buffers from the dv source are not perfectly aligned and they
should (unless there is a frame drop) because framerate is a constant in this
format. 

The timestamps follows the following rule (without considering lost frames:
ts = n_frame * 1/25 + jitter

This jitter in the timestamps should be corrected by the demuxer.

Could you guys review the patch or suggest a better approach?
