YouTube doesn't play after update to 5.15 #45

It starts playing for a few seconds, then playback stops. Note that vimeo and rutube videos play just fine so it must be something specific to the codec YouTube uses.

Right click on the video and choose "Stats for nerds". It will show the codecs used, likely Opus for audio. If you can disable Opus, Youtube should fall back on a different codec, likely AAC if that is enabled.

Yes, it's Opus for audio but it is Opus in 5.13.1 as well and there it works just fine. So it must be some regression in Chromium itself.

This is from 5.15:

Seems to be an av1 (libdav1d) issue, vp9 videos play fine.
