Hello.

This is a recent regression. I can only saw it on build starting December 1st, 2020. When I go to youtube and want to play a video, there is a message error. Video cannot be played.

When I launched Firefox from command line, I got this error log:

I'll try to find a regression windows asap this afternoon.

Looks like a video decoder failing, but it's not clear why. A regression range would help a lot. The info from about:support would also be useful.

Sorry for late reply. I was not able to reproduce this bug using nightlies. I think there was a bug in Archlinux packages which got fixed because I can get youtube video to work again.

So it must have been an archlinux bug. Sorry for bugspam.
