1881569 - Overlay doesn't seem to be used on windowed YouTube playback on Intel gen12 laptop

Status: RESOLVED WORKSFORME

(Core :: Graphics, defect, P1)

Description

[Jeff Muizelaar [:jrmuizel]]

When playing https://www.youtube.com/watch?v=LXb3EKWsInQ at 4k in Edge I see time being spent in "Video Processing" in task manager. I do not see time in "Video Processing" spent there in Firefox Nightly.

Intel Power Gadget also shows an appreciable difference in power usage.

Sotaro, is that what you'd expect? Do you know what we need to do to fix it?

I wonder if the problem might be similar to Bug 1849680. Or video overlay was disabled by about:config.

:jrmuizel, can you attach about:support to this bug after the problem happens?

With my Win11 laptop with intel GPU, I confirmed Video Processing" in task manager with the youtube video.

And can you also take profiler with "Media" setting? Is video overlay used with other videos

When I tried playing 1080p video it looked overlay was working. When switching to 4K it stopped and it looks like this is probably caused by the "Hw video swapchain present is slow" error.

It seems to hit the following slow commit check. If mCompositionDevice->Commit() takes more than 20 ms five times in a row, the video overlay is disabled.

Assigning to Sotaro, and setting to P1 for internal Graphics tracking.

Intel Gen12 also has a performance problem of hardware video decoder(Bug 1888354 , Bug 1890622). Part of the problem is addressed by Bug 1888354.

:jrmuizel, can you check if the problem still happens with latest nightly? I wonder if Bug 1896823 might affect to the problem.

I don't see the problem with the latest nightly.
