Hard to say.
We had an earlier version in production created about a year ago that works
fine, but it has many differences: it used FLV for capture, an much older
version of Ubuntu/ffmpeg and the video was much less demanding so it's
possible that glitches happened but didn't show up.
We've made upgrades everywhere, and this intermittent new one has only
recently showed up as we don't normally check more than a couple seconds of
video in qa, and it's intermittent sometimes the glitch is not noticeable,
it's only now we've created the test case to really show the issue.
Given the rapid stream of updates in ffmpeg, ubuntu, codecs, it's taken us
awhile just to see this issue clearly, and have some idea of where it's at.

Is there a flag to turn on/off to test?
