1125358 - Video buffers forever and never starts playing

Status: RESOLVED WORKSFORME

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

Description

[cmtalbert]

Attachment: mozmedia.log

Using 36b3, I do the following:
1. Go to this video: https://www.youtube.com/watch?v=2Q1EDFA0U2s
2. And after I skip the ad, it just starts buffering and never starts playing.

If I do this on release (35) with flash, it works fine and plays immediately.

I will attach a log file.

Here is the graphics section of about:support for this laptop.

I'm going to mark this as closed on the basis that we've totally rewritten our MSE implementation since this bug was filed. Re-open if there is still an issue.
