Could you help us out by trying to capture a Firefox performance profile when this happens? Visit https://profiler.firefox.com/ for more information and to enable the profiling toolbar button. When capturing, please select the Media profile in the button drop down, upload the resulting profile and post the url here.

Yes, there is a h264 1MB video test https://share.firefox.dev/40BomGh

You're dropping practically every frame here.

In about support, can you post your graphics section? I wonder if your card/driver are getting blocked from accelerated rendering.

Additional test https://test-videos.co.uk/vids/bigbuckbunny/mp4/h264/1080/Big_Buck_Bunny_1080_10s_10MB.mp4 it's

about support shows accelerated rendering. Not sure what's going on here.

Comment 9

[Elle Solomina (she/her)]

Yes, but the hardware decoder for h264 that exists in the system not detected.

It's weird, I wonder why your about:support has so many lockedPreferences... Can you try to use a new profile of Firefox to see if it works? In addition, do you install vp9 and av1 extension on your system? Thanks.

Well, I deleted my custom politics.json from the installation and after this Firefox only runs much slower and all elements look massive. But nothing fixed in the playing, it's still not working at all and hardware support for h264 isn't detected.

Could you help me capture a media profile when playing a H264 (or other codecs you want to have hw support) file by following this instruction. Please start profiling first, then play the video file. Thanks!

The test video is here https://html5videoplayer.net/html5video/mp4-h-264-video-test/

Comment 15

[Alastor Wu [:alwu]]

Hi, I just wanted to confirm—was the profile in comment 13 captured using about:logging? It doesn’t contain any logs, so it’s still difficult for me to determine why hardware decoding wasn’t enabled. That said, this could potentially be a bug with the profiler itself; we’ve seen cases where it should have captured logs but didn’t.

Could you help capture another profile and check if any logs appear? You can verify this by:

1. Clicking the MediaDecoderStateMachine thread in the tab where the video is playing
2. Clicking Marker Table
3. Typing log in the Filter Markers field

You should see some logging there. If not, let me know and we can try an alternative way to capture the logs. Thanks!

[Elle Solomina (she/her)]

Hmm, I recreated the profile, now it's probably fine https://share.firefox.dev/3RzqXe1

Comment 17

[Alastor Wu [:alwu]]

Okay thanks, I see Hardware video decoding disabled or blacklisted in your profile. So it seems that your graphic card and driver combination would cause some crashes, which make us disable the hw decoding explicitly. You can try to set the pref media.hardware-video-decoding.force-enabled=true then restart Firefox to see if it helps. Thanks!

[Elle Solomina (she/her)]

Option media.hardware-video-decoding.force-enabled is already set true, but it's not working as expected.
