Re: chromium: hardware video acceleration with VA-API

Hi, I have noticed, that usage of

--use-gl=egl

with brave instantly floods my Xorg.log with ton of messages like this:

[  1192.270] (II) modeset(0): EDID vendor "TMX", prod id 5472

Each tab switching produces couple of such blocks of messages and during video playback the rate of such mesaages becomes absolutely insane.
That applies to any chromium-based browser I have tried to use.

Could you please check your Xorg logs, it seems that such behavior may reduce SSD lifespan.

I am absolutely sure about that.

Messages in your log are absolutely OK, because they are produced only once at Xorg startup (look at the timestamps) and I bet, you only see them just at the beginning of your log file.

In my case there are literally thousands of them, because they are produced constantly during video playback and tab switching. They appear in such quantities only when I enable egl option. When egl is not used they appear only once at the beginning of log file, just like in your case.

Re: chromium: hardware video acceleration with VA-API

Hi, I notice a regression on NVIDIA lately. I can't get video acceleration on NVIDIA (via libva-vdpau-driver-vp9-git). I'm ashamed to say I'm the maintainer of this package, but well...

If I use

--use-gl=desktop

then the GPU process failes to boot upright. With

--use-gl=egl

the process boots but I don't get any accelerated decoding. If I open up chrome://gpu/, I see that "Video Acceleration Information" is just plain blank for both encode and decode.

Anyone has a fix to this problem? I use the flags:

--enable-features=VaapiVideoEncoder,VaapiVideoDecoder,CanvasOopRasterization,RawDraw,VaapiVideoDecodeLinuxGL
--disable-features=UseChromeOSDirectVideoDecoder
--use-gl=egl
--enable-zero-copy
--ignore-gpu-blocklist
--disable-gpu-driver-bug-workarounds
--enable-gpu-rasterization
--enable-raw-draw
--enable-oop-rasterization
--enable-gpu-compositing

Enabling or disabling Vulkan doesn't change anything.

Looks like that particular flag was removed in chromium 110.

Thanks. I tried removing all --use-gl flags, but then I get a blank screen (known issue w/ libva-vdpau-driver-vp9-git, any help highly appreciated). EGL doesn't work either...

Re: chromium: hardware video acceleration with VA-API

I've almost managed to work vaapi in my browser with Vulkan. Intel_gpu_top shows that acceleration is used, but in youtube video I see distorted picture, as if it was text and rows were shifted.

What can cause such behavior?

Re: chromium: hardware video acceleration with VA-API

I've managed to get acceleration with ONE format: h.264. I had to use this:

aur/chromium-wayland-vaapi 110.0.5481.100-1 (+11 0.65) (Installed)
Chromium, patched to enable VA-API video decoding on the Ozone Wayland backend

...and I had to launch it with a basket of switches:

--enable-features=VaapiVideoDecoder --use-gl=egl --enable-features=VaapiIgnoreDriverChecks --ozone-platform=wayland

This under Wayland (obviously) with amdgpu and a Polaris10.

I've had ZERO success getting any acceleration with google-chrome-stable. Firefox will also accelerate h.264 with MOZ_PLATFORM_WAYLAND=1 and a bunch of overrides in about:config -- no idea which one actually made it happen.

Some of this can be blamed on my circa-2016 GPU which lacks VP9 and AV1 hardware decode. But h.264 ought to "just work" and it doesn't. I've spent hours on this and I've even tried some flatpaks (the Microsoft Edge flatpak can be coaxed into h.264 h/w decode if you stroke it just right).

Re: chromium: hardware video acceleration with VA-API

I updated my patch to support AMD Vulkan drivers with VaapiVideoDecoder, it now works with Chromium 110: https://gist.github.com/thubble/235806c … 9173d24d9f

It looks like the Chromium devs added some infrastructure for supporing AMD's disjoint VAAPI planes, but it's not yet complete. I tried using the helper methods they created to bind disjoint planes, but it actually caused a GPU reset. So, it still needs this hacky patch. Hopefully they'll get it actually working soon.

With the patch, I get full zero-copy acceleration (on X11/XWayland) running with

--enable-features=VaapiVideoDecoder,UseChromeOSDirectVideoDecoder,VaapiIgnoreDriverChecks,PlatformHEVCDecoderSupport,Vulkan,DefaultANGLEVulkan,VulkanFromANGLE

Wayland native probably won't work because it doesn't support using the Vulkan backend for ANGLE. (ANGLE landed support for it recently, but it hasn't been enabled in Chromium).

Theoretically, Intel GPUs should work fine (on X11) with the above flags, with no patches (unless you want to add HEVC support).

Re: chromium: hardware video acceleration with VA-API

I have no issues with hardware acceleration using chrome based browsers and nvidia card with libva-vdpau-driver and libvdpau-va-gl be it google chrome and opera, both being Flatpak package btw.

Re: chromium: hardware video acceleration with VA-API

So completely random versions, what is kinda unrelated to the ongoing thread.
Also libva-vdpau-driver and libvdpau-va-gl is cyclic - one does vdpau over vaapi and the other vaapi over vdpau.

It's good that you have "no issues", but I'd look into about:gpu to see what you're actually using there…

Re: chromium: hardware video acceleration with VA-API

--use-gl=angle seems to be working for me on nvidia with brave. I'm accelerated with it, and unaccelerated without it. But I've also been experiencing periodic 1-2 second freezes under x11 since doing this, which go away after backing out of this change, occurring across multiple systems. I've had no luck tracking down a cause or even an event in any log file, so if this works for you but also results in freezes, I'd like to know.

--enable-gpu-rasterization
--enable-zero-copy
--enable-features=VaapiVideoDecoder

chromium 109.0.5414.74 is the last one that works with  libva-vdpau-driver-vp9-git and use-gl=desktop and nvidia. Keeping it they manage to make VaapiVideoDecoder work under nvidia vulkan

With the same flags, I am indeed accelerated on Chromium too, but unfortunately the video does not get rendered which makes this useless...

For my Intel Kaby Lake following lines from [gbcbooks] worked well to GPU accelerate.

--use-vulkan
--enable-features=VaapiVideoEncoder,VaapiVideoDecoder,CanvasOopRasterization
--disable-features=UseChromeOSDirectVideoDecoder,UseSkiaRenderer
--disable-reading-from-canvas
--webgpu
--ignore-gpu-blocklist
--enable-raw-draw
--disable-gpu-driver-workarounds
--use-gl=egl

Today I updated the system again...and acceleration was gone.
Chromium 112.0.5615.49
libva 2.18
intel-media driver 23.1

Your suggestion to set LIBVA_DRI3_DISABLE=1  in  /etc/environment did not bring it back.

Can someone please help me out please?
Thanks in advance.

Re: chromium: hardware video acceleration with VA-API

I had to start using --use-gl=egl a while ago or else vaapi wouldn't work (i only needed VaapiVideoEncoder enabled and UseChromeOSDirectVideoDecoder disabled before).
Now --use-gl=egl  breaks hardware acceleration entirely (literally everything on chrome:gpu gets disabled) so it seems there's literally no workaround for me anymore lol.

Re: chromium: hardware video acceleration with VA-API

indeed update to v112 killed vaapi. I was able to get it working again with the following flags.

--pasword-store=gnome
--ozone-platform-hint=auto
--extension-mime-request-handling=always-prompt-for-install
--enable-features=WebUIDarkMode,VaapiVideoDecoder,VaapiVideoEncoder,RawDraw,CanvasOopRasterization
--disable-features=UseChromeOSDirectVideoDecoder,SidePanel,UseSkiaRenderer
--force-dark-mode
--use-vulkan
--enable-gpu-rasterization
--enable-zero-copy
--enable-hardware-overlays
--enable-native-gpu-memory-buffers

I think --use-vulkan doesn't help so you could remove it.

Edit: I also had to start using this env variable. LIBVA_DRI3_DISABLE=1

My cpu is i7-11800H
