--- Comment #1 from Sebastian Dröge (slomo) <slomo at coaxion.net> ---
So the first question would be if such a small duration is actually correct
here. Are you really capturing with such a high framerate and also want to
record it like that? My guess is that those duration values are wrong to begin
with.

Then in vpxenc we should catch the 0 duration and do something about it, e.g.
replacing it by 1 or erroring out in a more meaningful way. For the rate,
there's the timebase property on vpxenc that you can use to manually set it. It
defaults to 90000 because that's usually a good default for various reasons.
