1115096 - Audio stops / seeking fails with YouTube MSE webm/vp9

Status: RESOLVED WORKSFORME

(Core :: Audio/Video: Playback, defect, P5)

Description

[Karl Tomlinson (:karlt)]

1. Load https://www.youtube.com/watch?v=CO6OZIY-lYw
   Warning: Christmas carol secularized by boy band.

2. Play, skip ad.

3. If sound is still playing after 2:20, allow to play a little longer, and
   then seek backwards to a point after 2:20.

Expected: playback resumes from seek point.

Actual: playback pauses for a second or two showing throbber and then resumes
        from previous playback point.

4. Seek to a point shortly before 2:20

Expected: playback resumes from seek point with audio.

Actual: playback resumes from seek point and then audio stops when playback
reaches 2:20.

(Behavior is as expected without MSE.)

Tested with 2014-12-22 nightly b915a50bc6be.
Didn't reproduce with mp4.

Seems like we should fix the known webm issues in bug 1093133.

I'm going to close this. Re-open if you reproduce it again with WebM.
