User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:90.0) Gecko/20100101 Firefox/90.0

Steps to reproduce:

I went to a website and played a video.

Actual results:

The video was not showing, instead a black screen I could see in the player. The player controls were working, the sound was perfect. But instead of the video, I was watching a complete black frame. It shows black in both full screen too.
It does not happen always. Most of the time the video works great. Sometimes when I am using firefox for a quite long time, this issue appears. If I restart, everything works great.

Expected results:

I should see the video.

Thanks for the report. Could you install the Firefox profiler and when you next encounter the issue, collect a profile using the "Media" setting in the profiler (it should be in the drop down list)? Once you've gathered the profile, could you use the 'Upload local profile button' and past the link onto this bug? Thanks!
