Video Decoding problem (nVidia+Windows11+Nightly)

Youtube seem to be having problems with video decoding, previous frames seem to be displayed from time to time. for ex, this video: https://www.youtube.com/watch?v=dFhzMEnCEhY

The same profile works on Firefox 134.0b8 (64-bit) without problems, but not on nightly. If I just disable `media.hardware-video-decoding.enabled` and restart, then the problem goes away on Nightly.

Enabling/Disabling my user customizations don't seem to affect it. Enabling/Disabling addons don't affect it. Using a new empty profile also doesn't affect it, the problem persists. I tried deleting "gmp-widevinecdm" folder and redownloading it, still didn't solve the problem.

I seems to be some sort of regression, it used to work before a couple of days ago. Please fix, I hope the information I provided helps, as I like having hardware acceleration.

I also tried to update the display driver. nVidia Driver: 31.0.15.5176 now 32.0.15.6636

Chosen solution

Found the problem, its the av01.0.08M.08 codec. If I force h264 using h264ify suggested in another answer, then youtube uses avc1.640028 , then the problem goes away with `media.hardware-video-decoding.enabled` set to the default (enabled)

The post http://forums.mozillazine.org/viewtopic.php?p=14989107#p14989107 may have related Bugs for Youtube issues in very recent builds of Firefox Nightly.

Please read https://bugzilla.mozilla.org/page.cgi?id=etiquette.html before considering commenting in any Bugzilla Bugs.

The more unstable Nightly development channel meant for devs and testers in mind gets checkins and updates twice a day so you are bound to encounter issues until it is fixed, finished or reverted.

Sorry about the confusion, I forgot to look for the bug there. I never had seen such a problem with a core component with the nightly, I thought it was some problem in my machine.
