[BugBot [:suhaib / :marco/ :calixte]]

Since nightly and release are affected, beta will likely be affected too.
For more information, please visit BugBot documentation.

Comment 2

[Dennis Schubert [:denschub]]

This seems to be working fine for us in the triage meeting now. Is this still broken for you, Calin? Do you see any exceptions in the JS console?

Attachment: Console errors.png

Updated to 137.0a1 (2025-02-05) but the issue still reproduces.

In some cases if I leave the page open long enough it will become unresponsive and it will show the warning that it slows down the browser. I've captured a performance profile: https://share.firefox.dev/4gvM9vs

Comment 4

[Dennis Schubert [:denschub]]

I see a media decoding error in that screenshot, so let's see if the media team has an idea. I'll set "affects users: some", though, because this appears to be intermittent.

Comment 5

[Jim Mathies [:jimm]]

Where is the live image the report refers too? I see a scrolling image of a city on the main page.

Comment 6

[Jim Mathies [:jimm]]

Never mind, I see now that the scrolling image is actually a live video feed in Chrome.

Comment 8

[Jim Mathies [:jimm]]

Looks like this might be related to drm or openh264, although I'd be surprised if I had an issue with H264.

Comment 9

[Jim Mathies [:jimm]]

Profile with media logging -
https://share.firefox.dev/4hIduvR

Not seeing much here that points to the specific issue. Possibly some sort of format issue?

This appears to point to an issue with the content and openh264 -

On my system though, not sure why I would get openh264 since I have platform h264 decoding.

Hey Ashley, maybe you can try to diagnose this for us? Thanks.

Looks like an error demuxing video, with many errors similar to the below:

We do manage to decode a bunch of samples:

I edited the source so that we wouldn't suspend regardless here and made sure that autoplay is enabled, but this didn't fix playback. Even changing that code, there'd still be some issues reading the next moof:

I captured a Pernosco session of the unpatched source here. There are many errors re: invalid moofs. padenot, would you have any ideas?

[Paul Adenot (:padenot)]

Reporter, please get us media playback logs with about:logging:

• In Firefox, ideally freshly started with no other tabs, go to about:logging in a new tab
• Select the Media preset and click Start Logging
• Reproduce the bug
• Back on about:logging, click Stop Logging
• In the new tab that appears with the Firefox Profiler web application, in the top right click the button to upload the profile
• Make sure hidden threads are included and upload, then share the link here or send privately to a Mozilla developer

Here are the same instructions, in video form, if you prefer that https://paul.cx/public/about-logging-presentation.webm

It works here on macOS, I can pan the live image, and it is live, e.g. I see cars moving.

Comment 16

[Jim Mathies [:jimm]]

This video is larger than Media Foundation and D3D11 decoder support, (max resolution support for WMF H264 is 4096). Chrome falls back to using the ffmpeg decoder. Due to the patent issue, we can't do that.

Comment 17

[Jeff Muizelaar [:jrmuizel]]

Could we use OpenH264 for the high resolution vidoes?

Comment 18

[Jim Mathies [:jimm]]

Alastor, would something like this be possible?
