Okay, this build restored the video playback functionality but the performance is horrible running at only few FPS, now including other web-sites as well, like YouTube with vp9 and ac1 codecs. This is on RX 6700XT.

Please file that at bugzilla.redhat.com. I don't see that on RX 6600XT. Also we're supposed to switch to SW decode when VA-API fails.

This update has been unpushed.

Thanks for testing, will check in Intel then.

I tested the update from 100 to 101 and the plugin is not changed. Looks like the change was made in some previous version. You need to go to about:config, find gmpopenh264 keys and reset them to default values. media.gmp-gmpopenh264.version needs to be system-installed. also make sure mozilla-openh264 package is installed (it's optional).

You're right - only Mozilla provided one is used, Fedora openh264 system wide plugin is ignored.

You should see openh264 on about:plugins page.

Hm, openh264 works for me after update.

Will try the openh264 codec, thanks.

Added.

Please also give karma to https://bodhi.fedoraproject.org/updates/FEDORA-2022-08fd8a24fd (nss update) which is needed for this one.

Okay, doesn't look like a bug then.

Hm, there's a focus URL bar regression in Fedora package: https://bugzilla.redhat.com/show_bug.cgi?id=2040293

nss is in stable now. Firefox 94 (new upstream) will come out next week.
