VAAPI does not work

[beew]

Chromium-browser 92.0.4503.0 Ubuntu 20.04 installed via the ppa

I started Chromium with

LIBVA_DRIVER_NAME=i965 chromium-browser --use-gl=desktop --enable-features=VaapiVideoDecoder

I have enabled override software rendering list and after starting Chromium this way I checked about:gpu and hardware decoding was enabled.

But went to Youtube to watch any video and checked Developer_Tools > Media and it showed that vaapi is not working and intel-gpu-top also show 0% under video.(as well the terminal didn't show any info about vaapi version and driver initiation and such)

I have installed h264ify addon on Chromium. VAAPI for the same videos works in Firefox.

When Chromium started I got these errors

[833744:833744:0705/001603.508396:ERROR:gpu_init.cc(441)] Passthrough is not supported, GL is desktop
[833744:833744:0705/001603.552650:ERROR:sandbox_linux.cc(374)] InitializeSandbox() called with multiple threads in process gpu-process.

I have intel ivybridge graphic, no Nvidia.

Sorry I should be clear this is ver92 from the dev ppa. ver91 in the beta ppa works.

Looks that HW decode (VAAPI) doesn't work at all on NVIDIA in the recent 95 build...
No problems in 93.

And as bonus: bad web fonts render in 95.

Actually VAAPI doesn't work for Chromium 95 because there is no way to disable the ozone platform which atm doesn't support VAAPI. It has nothing to do with Nvidia, it doesn't work on Intel either. The good news is there is a commit that fixes it and it will land on Chromium 96. So just skip 95.

@xswqaz Can you run Chromium from the following command line with these arguments, and paste the output here? Hopefully there's a bit more info there.

chromium-browser --enable-logging=stderr --log-level=0 --vmodule=vaapi_wrapper=4,vaapi_video_decode_accelerator=4

[xswqaz]

Here is log

After setting "Enable software compositing window manager" on
It enabled to VDAVideoDecoder youtube
But, screen is black. what's wrong?

[saiarcot895]

I'm suspecting it's something specific to do with NVidia, but not sure what. AMD appears to be working fine.

[marioroy]

I added a script today to install this chromium-ubuntu-build and it works great with NVIDIA graphics including hardware video acceleration. The GitHub repository builds both VA-API drivers for NVIDIA graphics.

Can you guide the same for Arch Linux as well? It's a hazzle for me to not have a working VA--API decoder.

@pc00per
You can vaapi decode with Window manager GLX setting
and option --use-gl=desktop

No need to customize chromium version

Tnx. But I've tried desktop glx & it's of no use. None of my browsers decode using hw acceleration at all. Chromium strictly stick to VpxVideoDecoder whatever I do.

Have you tried with chrome Official version?

--disable-features=UseChromeOSDirectVideoDecoder
--enable-features=VaapiVideoDecoder
--use-gl=desktop

and You need to install vdpau-va-driver backend. No problem with vainfo

I've tried everything. Modifications of flags has nothing to do with the absense of hardware-accelerated-video-decode
It's the browser's vaapi issue (failed to Initialize VaapiVideoDecoder)

Youtube default codec is vp9, and I recommend plugin h264ify
