Intermittent black videos on Youtube
For the past week or two videos on Youtube have been intermittently appearing as solid black. Audio always works. It's definitely using the <video> player and not the flash one. I tried disabling mediasource in about:config and that didn't address the issue. A few things I've noticed: Usually this video plays an ad when loaded, but any time the page is black no ad plays. Maybe this is from a failed ad load/play since they try to blank out the video behind the ad? Doesn't explain why the video is playing audio, though.

Might be a youtube-side change and not an FF change.
Anthony - I'm guessing this is MSE related but don't have proof yet.
Oh. Just realized that the report is from a month ago. We've done a lot of work on MSE in the last month. Does this still reproduce?
As this is intermittent as was only fixed last week, we'll have to see if this reproduces over the next week or so. Can you please let us know if you experience any more black screens on YouTube?
I'm clearing tracking as it's not clear that this issue still impacts the release (no other reports) and marking 37 as affected.
We've blocked a number of video cards which cause a similar sounding problem, but I don't believe we included this one. Are you still seeing this problem?
I haven't seen this in a while. It might have gone away because I switched to 64-bit Developer Edition.
