Any luck for me?

I get the same errors as yours with Mesa 24.1 and Chromium 125. Did you find any solution?

What GPU do you have?

If you have an AMD one, you need to enable Vulkan - either on x11 now or optionally with Wayland once the Arch Chromium package rebuilds for 125.0.6422.141. Hmann's patch works by conforming the VA-API behavior but Chromium only triggers the correct code path when Vulkan is used as the render backend.

If it's Intel, you didn't need hmann's patch (which is now available at https://archlinux.org/packages/extra/x86_64/mesa/ regardless) but you do need to add VaapiVideoDecodeLinuxGL to your Chromium feature flags. Not sure about NVIDIA.

It's an old laptop with Radeon R5 graphics (which might be the case, as HW acceleration works fine on my main PC.). Mainly using it for YouTube and hardware acceleration was all fine until Chromium 116. I just sticked with 115 before Hmann's patch was merged.

I'm using these flags:

--ozone-platform=x11
--use-gl=angle
--use-angle=vulkan
--enable-features=Vulkan,VulkanFromANGLE,DefaultANGLEVulkan,PlatformHEVCDecoderSupport,UseMultiPlaneFormatForHardwareVideo,VaapiVideoDecoder,VaapiIgnoreDriverChecks,VaapiVideoEncoder

And getting this when I try to play any video:

Are you using "amdvlk" by any chance? Review https://wiki.archlinux.org/title/AMDGPU#Installation if you aren't sure.
You want to be using https://docs.mesa3d.org/drivers/radv.html (packaged in Arch as https://archlinux.org/packages/extra/x8 … an-radeon/) if you can. Chromium has a bunch of workarounds for "amdvlk" and I would not be surprised if one interfered.

Something else to check is if libva-mesa-driver is installed and if `vainfo` does contain the codec for the video you're testing with.

No, it doesn't work for me, I have vulkan-radeon.

Here's the output of vainfo:

Pretty sure H264 should work, well as it did before. So I'm really confused what's wrong.

Re: chromium: hardware video acceleration with VA-API

Works for me on 6650xt with mesa 24.1 using these flags:
--use-angle=vulkan
--enable-features=Vulkan,VulkanFromANGLE,DefaultANGLEVulkan,VaapiIgnoreDriverChecks,VaapiVideoDecoder,UseMultiPlaneFormatForHardwareVideo,VaapiVideoEncoder

with xwayland, on wayland it disabled gpu for anything in browser, chrome 125.0.6422.141

edit: With https://aur.archlinux.org/packages/goog … and-vulkan works even with full wayland using --ozone-platform=wayland

Re: chromium: hardware video acceleration with VA-API

I absolutely love this massive thread. I will contribute my part by showing what worked for me on my hardware:

Google Chrome version 125.0.6422.141 (from google-chrome AUR)
Thinkpad P14s G4 with AMD 7840U
Plasma 6.0.5 on Wayland with mesa 24.1
Using basic recommended setup from AMDGPU archwiki page and VAAPI on Hardware Acceleration page
6.9.3-arch1 vanilla kernel

Chrome flags:

--enable-features=VaapiVideoDecoder,VaapiVideoEncoder,UseChromeOSDirectVideoDecoder,VaapiIgnoreDriverChecks,Vulkan,DefaultANGLEVulkan,VulkanFromANGLE
--use-gl=angle
--use-angle=vulkan
--use-vulkan=native
--ignore-gpu-blocklist
--enable-zero-copy
--enable-gpu-rasterization
--enable-native-gpu-memory-buffers
--enable-gpu-memory-buffer-video-frames

I noticed the patch works just fine on AMD, but it produces a lot of tearing on GeForce Now, making it unfit to game on. Does anyone else here experienced this? Using the latest stable version of Google Chrome. It occurs on all chromium derivatives as well. On X11 and xWayland.

The tearing is happening on my AMD Ryzen 7 6800U, 680M too with the latest mesa 24.1, wayland and latest Brave v1.66.118.
I am using these flags:

--enable-features=VaapiVideoDecoder,VaapiVideoEncoder,UseMultiPlaneFormatForHardwareVideo,VaapiIgnoreDriverChecks,Vulkan,DefaultANGLEVulkan,VulkanFromANGLE
--use-angle=vulkan

The youtube hardware acceleration finnaly started working. But the tearing is so annoying sometimes that I will disable the flags now which will disable the hardware acceleration again.

Make sure to include

--ozone-platform-hint=auto

to actually enable Wayland support. Also try with the chromium package, Brave might not include the patch that allows Wayland + Vulkan.

Just tried with that flag, but the hardware acceleration doesn't work then on youtube.
I tried the bottom flag too and it doesn't work then either.

Are you using the Chromium package in the Arch Linux repo? The Arch package includes a patch to enable Va-api acceleration in Wayland. It will not work for brave-bin in the AUR. The google-chrome AUR package also does not have Va-api acceleration in Wayland. The google-chrome-wayland-vulkan AUR package works with Va-api in Wayland.

Does the Vulkan support work only with mesa drivers?
cos I'm using nvidia and it certainly doesn't work for me

Re: chromium: hardware video acceleration with VA-API

[NEWS]

I just found out that MS Teams video conferencing on my browser (Vivaldi 6.7.3329.41 (Stable channel) stable (64-bit) ) uses hw accelerated encoding/decoding.
I could see that with "sudo intel_gpu_top".
I also tested that Google Meet and Zoom still use sw encoder/decoder.
It would be nice to know how it works!
Vivaldi, like any other chromium-based browser, supports "WebRTC hardware video encoding/decoding" only on Android (where it is pretty useless) and ChromeOS (where it makes senes) as per "vivaldi://flags".
Nonetheless I saw both "Video" and "VideoEnhance" values going up and down during my calls.

My system:

YT hw decoding works great to me (vivaldi browser) and I don't have any specific extension (only "Plasma integration").

I guess your hardware supports vp9 because otherwise it falls back to software decoding rather than h264.

That's really weird, this is not how youtube behaved last time I've had an h264 only video card.
Also youtube doesn't encode anything beyond 1080p or 30fps in h264.

Yes, indeed.
But this what happens to me.
Maybe someone else can provide for more tests and possibly compare their setup with mine.
When I will get also Zoom, Meet and Slack Huddles work like that I will be really happy: it's the only pesky thing so far on mi ArchLinux daily driver.

My vainfo output.

It looks like there is both support for a number of codecs: MPEG2, VC1, H264, HEVC and VP9 among a few others.
Unluckily I have partial knowledge on how this gfx stack is organized and works.

VDPAU is mostly an nvidia thing and you'll only use it through a translation layer and not at all with browsers.
The VAAPI situation is relevant and you're getting an AV1 video that your IGP can decode in HW.
