--- Comment #13 from Edward Hervey <bilboed at bilboed.com> ---
All those files you provided have MPEG-4 Video, and that seems to be the root
cause. mpeg4videoparse never seems to get a proper config, and therefore drops
everything without pushing anything.

I would much prefer we detect (and fix) such root cause issues instead of
adding workarounds in decodebin3 (which as you realized isn't easy either :D ).

We definitely shouldn't hang like this. What should happen is that
mpeg4videoparse (or baseparse) should detect that it isn't producing data and
pushing GAP events downstream which ... then brings us to the other baseparse
