1755526 - Intel: VA-API FFmpeg is disabled by platform

Status: RESOLVED DUPLICATE of bug 1751363

(Core :: Graphics, defect)

Description

[nimroot]

Attachment: about-support

User Agent: Mozilla/5.0 (X11; Fedora; Linux x86_64; rv:97.0) Gecko/20100101 Firefox/97.0

Steps to reproduce:

Start the latest Firefox compiled from source with:

MOZ_LOG="PlatformDecoderModule:5" ./mach run

and visit a website that plays a video content e.g. https://www.youtube.com/

vainfo log:

libva info: VA-API version 1.13.0
libva info: Trying to open /usr/lib64/dri/iHD_drv_video.so
libva info: Found init function __vaDriverInit_1_13
libva info: va_openDriver() returns 0
vainfo: VA-API version: 1.13 (libva 2.13.0)
vainfo: Driver version: Intel iHD driver for Intel(R) Gen Graphics - 21.4.3 ()

about:support attached as a file.

Actual results:

The following is logged:

[Child 26496: Main Thread]: D/PlatformDecoderModule FFMPEG: VA-API FFmpeg is disabled by platform

I've also verified with intel_gpu_top that indeed, video acceleration doesn't work.

Expected results:

This seems like a regression, because VA-API integration with Firefox used to work on my system when I compiled it some time ago (I believe it was FF97).

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

The Bugbug bot thinks this bug should belong to the 'Core::Graphics' component, and is moving the bug to that component. Please revert this change in case you think the bot is wrong.

Does it work if you run
$ MOZ_DISABLE_RDD_SANDBOX=1 MOZ_LOG="PlatformDecoderModule:5" ./mach run
? (bug 1751363)

No. I think that for some reason either my hardware or the driver version is blacklisted.

Can you turn on the DMABuf logging and attach the output? From your about:support, I would expect it to be turned on so I am a bit puzzled as to why it is failing.

MOZ_LOG="PlatformDecoderModule:5,Dmabuf:5" ./mach run

[Child 26496: Main Thread]: D/PlatformDecoderModule FFMPEG: VA-API FFmpeg is disabled by platform

You might just be looking at the wrong line.
VAAPI is not enabled for Parent or Child processes, but it should work in RDD.

If you see

FFMPEG: VA-API Got one frame output with

then it's definitely working.

MOZ_LOG="PlatformDecoderModule:5,Dmabuf:5" ./mach run

I've attached full log from an example run with a 1080p video at Youtube to the bug.

I think that this part might be especially interesting (failed to create GL context?):

[RDD 35713: MediaPDecoder #2]: D/PlatformDecoderModule VideoFrameSurfaceVAAPI: creating surface UID = 1

MOZ_LOG="PlatformDecoderModule:5,Dmabuf:5" ./mach run

That command would be affected by bug 1751363.
Please attach log of:
$ MOZ_DISABLE_RDD_SANDBOX=1 MOZ_LOG="PlatformDecoderModule:5,Dmabuf:5" ./mach run

Alright, this indeed works. I've got confused before because my hardware doesn't support AV1 and currently Youtube often offers the video content using AV1, which was the case during my testing. If I play the videos with disabled RDD sandbox and disabled AV1 it does work, so I suppose that this issue can be resolved.

I think we can consider it a dupe of bug 1751363 then. Thanks for the help Darkspirit/nimroot! :)
