I've just looked at this, and Cheese (through oggmux) now seems to output
correctly muxed video.
However, it outputs video with insane bitrate (quality based, but with only
keyframes - I assume that's to make it easy to edit).
It also sends pages very quickly, leaading to substantial framing overhead (12%
for Vorbis on my 320x240 output, compared to 1% for typical use). oggmux's
max-page-delay is set to 10ms, which seems low.
There's also no (apparent) way to select a lower fps, which would help here.
This causes my computer to fail to keep up after a few seconds of recording,
which might conceivably be a cause of bad muxing, if somehow the Vorbis side of
the pipeline got stuck for some time. Doubtful though.
