Opening https://user-images.githubusercontent.com/49337058/150008204-4e77c0ba-1939-4e4b-9cce-0222d89d0d77.mov directly in Firefox plays.
What does happen? (Please don't only cover what does not happen.)

Flags: needinfo?(bugsgalore)

The video is stuck displaying only a single frame and the browser becomes unresponsive and laggy, scrolling is choppy.

I can reproduce this on macOS and it looks like decoding is too slow so frames cannot arrive on time and VideoSink drops them:
