Comment 15

[Jim Mathies [:jimm]]

From andreas - The frequent failure is mac-only oddly enough. two resize events instead of 3. so either some frame wasn't captured or it was dropped by the encoder. For gtests we disallow frame drops, we could do the same with mochitests via a pref. We already have "media.recorder.video.frame_drops", just need to flip it.

Comment 17

[Andreas Pehrson [:pehrsons]]

Speculative, but this gets rid of one source of skipped frames that is timing and machine dependent.
