--- Comment #11 from Vincent Penquerc'h <vincent.penquerch at collabora.co.uk> ---
The video I got from the hosting site is enough to show the problem, there is
no need for a longer video.

Mitigating the problem in this particular case would mean telling the muxer
(ffmpeg ?) to minimize the amount of video it pushes at once into the Ogg
stream, so that there is less of it between the comparatively rare audio pages.

I think what might be happening is that the muxer uses large audio pages, and
outputs them when they reach some set size. If the muxer has a way to set the
page latency, setting a lower latency should help get smaller audio pages out
more often, which means this will decrease the amount of video frames piling
up. Decreasing audio page size may also have the same effect, if the muxer can
do that.

Of course, this does not fix the overall issue, just this particular case of
you encoding this video.
