Re: chromium: hardware video acceleration with VA-API

Well, that does not help chromium-vaapi. GStreamer-vaapi already works for Intel GPU on Wayland. GNOME Web/Epiphany supports GStreamer and video playback can be accelerated on Wayland. The only problem with GNOME Web/Epiphany is lacking YouTube plugin to force accelerated video formats that are supported by the hardware.

If someone comes up with YouTube plugin for GNOME Web/Epiphany, then it will become a serious contender to chromium-vaapi.

Well gnome web/epiphany has a problem. Since it is built using gtk there is an excessive surface reconfiguration bug on Wayland which effects the performance drastically. For gst-vaapi, well unless export EGLImage to dmabuf is implemented, it won't work on amdgpus. There are lot of bugs to fix there.

I don't think those issues affect Intel GPU, but you are right that gstreamer-vaapi does not quite play along with AMDGPU/MESA VA driver.
Well, I just checked out GNOME Web/Epiphany on my Intel laptop with Intel Skylake GPU. I used test H.264 video from http://www.html5videoplayer.net/html5vi … ideo-test/ and intel_gpu_top was showing activities with the video engine. That means GNOME Web/Epiphany is able to leverage video acceleration through gstreamer-vaapi. This is on an up-to-date ArchLinux with GNOME/Wayland.

For those who have Kabylake+ Intel GPUs with VP9 support, GNOME Web/Epiphany should be able to have video acceleration for YouTube.

Re: chromium: hardware video acceleration with VA-API

Finally, I confirmed it myself that all the Wayland craps can be resolved by downgrading to xorg-server-xwayland 1.19.7, the last stable release from 1.19-branch.

commit 937391523eef6459d1f8b1ae25fe7e1f77b8a12a (HEAD, tag: xorg-server-1.19.7, origin/server-1.19-branch)
Author: Kevin Brace <kevinbrace@gmx.com>
Date:   Sat Mar 2 14:13:20 2019 -0800

    xserver 1.19.7
    
    Signed-off-by: Kevin Brace <kevinbrace@gmx.com>

And only this package, the rest of xorg-server packages can remain upstream. Moreover rubbing salt in the wounds, no matter how frustrated we had reported Wayland issues to Google Chromium team, they seemed to be triaging Wayland issues on Ubuntu 18.04LTS. Guess what? Ubuntu 18.04LTS is keeping xwayland from 1.19-branch while the rest of the Xorg packages at 1.20-branch! So, Google Chromium devs were not able to reproduce the issues!

So I did the same to my ArchLinux and boomed all the Wayland craps were resolved, no more V-Sync issue and chromium-vaapi perfectly plays back videos with acceleration with "--use-gl=egl" on GNOME/Wayland.

It is disappointing that the XWayland V-Sync issue with respect to Chromium is getting nowhere from the upstream. The upstream master-branch solved the V-Sync issue but chromium performance remains poor when flag "--use-gl=egl" is used. And it is not just for VA-API, typical page 2D rendering and WebGL are all affected by poor performance whenever the flag is used.
https://bugs.chromium.org/p/chromium/is … id=1041228

Unfortunately for Intel GPUs, "--use-gl=egl" is the only way to get VA-API in action on Wayland session. I am now leaning towards that this is indeed Google Chromium issue to debug and fix the V-Sync of Chromium EGL surface presentation to match the behavior of xwayland from 1.20-branch, mostly likely due to the new multi-buffering scheme.

Re: chromium: hardware video acceleration with VA-API

Upstream Chromium acknowledged the bug and is working on the fix. smile

Issue 1041229: Flag --use-gl=egl unable to select gl::kGLImplementationEGLGLES2 during VADisplayState::InitializeOnce()

As expected, they did not simply take the ugly patch but will be fixing it the right way. Hopefully, next Chromium release will support hardware video acceleration on Wayland for i965 VA driver.

Re: chromium: hardware video acceleration with VA-API

liewkj: I am giving Wayland another try smile I noticed that if I launch chromium using "--use-gl=egl" using either driver, videos become very visibly laggy - is this known? Do you also experience this? If I use iHD driver, I do get MojoVideoDecoder, but as per the bug you referenced, i965 driver throws some errors. But these lags with --use-gl=egl are so visible...

You are definitely not alone smile, but we will have to wait for this bug to get traction and resolved at Chromium upstream.

Issue 1041228: Poor performance with --use-gl=egl on XWayland (GNOME/Wayland)

I am experiencing the issue on 4 different systems at my disposals, all running up-to-date ArchLinux with GNOME/Wayland.

  • NVIDIA GT730/nouveau - Desktop

  • Intel Haswell - Laptop

  • Intel Skylake GT2 - Laptop

  • Ryzen APU - Laptop.

Unfortunately since corporate worlds are all about Ubuntu LTS these days, the last 18.04LTS will not have the issue. For quick and dirty workaround today on ArchLinux, I just created custom AUR package for xwayland and keep it at 1.19.7, similar to Ubuntu 18.04LTS.

How did you conclude that video acceleration wasn't working for you in chromium-vaapi?
You need to show any errors indication that video acceleration wasn't working. Details from vainfo alone wasn't enough.
Are you on Wayland or Xorg session?

Re: chromium: hardware video acceleration with VA-API

I'd like to thank everybody for their work and dedication on chromium-vaapi (and chromium-vaapi-bin).
And, of course libva-vdpau-driver-chromium.
I rolled back to chromium 78, and glibc 2.30.
This still works.

For those interested, I have started an experimental project that modifies vdpau-va-driver (VAAPI wrapper) to include support for VP9 on NVIDIA GPUs. It seems to work for the videos I've tried so far and would appreciate more testers. Although I've tested only on Ubuntu 19.10, I don't think there should be any barriers for this working on ArchLinux.

Many thanks @xtknight, i compiled your build with the patch mentioned here https://github.com/xtknight/vdpau-va-dr … 9/issues/5 and for the past 2 days VP9 decoding works without an issue.
4K/60 FPS video running smoothly with MojoDecoder and the CPU usage below 100% and fans are quite

The only exception is when trying an 8K60fps video which just crashes immediately , 8K 30FPS is fine

I can see the following error ,
vdp_output_surface_create(1, 0, 7680, 4352, -)
    -> 23
vdp_get_error_string(23)
    -> 'The system does not have enough resources to complete the requested operation at this time.'


But my GPU (GTX 1070) can handle decoding 8k60fps using nvdec

For me that's OK because I only have a 4K monitor and I only tried the 8K60fps video to test your wrapper smile

If you want to debug anyway here is the chromium log

Re: chromium: hardware video acceleration with VA-API

Why do you think it is only a temporary removal? If it was removed at all, presumably it was for a reason?

...

IIRC maximbaz mentioned switching to wayland and therefore firefox, so I'm not sure he's still invested in this.

Re: chromium: hardware video acceleration with VA-API

Hello all,

I am using chromium-vaapi in the precompiled version from the Archlinuxcn repository, together with the libva-vdpau-driver-chromium patched according to the information from this thread, available from GitHub here.

GPU is a nVidia GTX550 Ti with driver version 390. I am on Xorg, not Wayland.

Is there anything that has to be configured in order to remedy the errors in the log?

Thank you very much and kind regards,

Re: chromium: hardware video acceleration with VA-API

@DAC324

That is a really old GPU, try using Nouveau and vaapi instead of the nvidia drivers and vdpau, it should work better.

Re: chromium: hardware video acceleration with VA-API

I was able to use nvidia-390xx on NVIDIA GT730 Kepler and VAAPI worked through the wrapper libva-vdpau-driver-chromium for Chromium-vaapi. That was after nvidia-390xx being dropped from official ArchLinux repo and moved to AUR. I had to build the drivers out from AUR for kernel 5.5.8. If you were unaware of the move that nvidia-390xx is now with AUR and what this means to you, then the first thing for you to do is to refresh the nvidia-390xx packages from AUR. That should rebuild the drivers for the upstream kernel.

With the package now in AUR, if you decided to keep on using nvidia-390xx, then you will need to install dkms and have to drivers rebuild on every upstream kernel update. Or search for unofficial repo that will do this for you, or as someone already suggested, start looking into Nouveau driver as a hassle-free alternative.

Re: chromium: hardware video acceleration with VA-API

I have Arch installed with the LTS kernel (the regular kernel crashes my Threadripper 3960X). I installed chromium-vaapi from ArchLinuxCN and also ungoogled-chromium (to test, as both have VAAPI enabled), but I've notcied something. On either package when I play h264 YouTube videos or whatever, chrome://media-internals shows MojoVideoDecoder, which is great. However, in chrome://flags the flags to enable hardware video acceleration are greyed out in the 'Not available on your platform' section. So what gives? Is it using VAAPI as per Mojo being listed, or isn't it, as per the flags being unavailable? I do have the flag to override the software rendering list enabled, btw, and chrome://gpu shows hardware acceleration in green.

First world problems and all, as my 3960X has so many threads I show less than 1% CPU usage either way, so that's not diagnostic. The radeontop package doesn't help either, as unlike the intel_gpu_tools package it doesn't have an entry for 'video'. While, as I said, it doesn't really matter either way on this system, it does on the other much feebler systems at home that I may wish to switch to Arch (from Ubuntu, Debian, Fedora, OpenSUSE etc). So I'm curious. Any ideas?

You do have video acceleration working when MojoVideoDecoder showed up. The chrome://flags simply reflects an unsupported feature in Linux. Any desktop class multi-core CPU in the last 10 years can do H.264 decode up to 1080p at no sweat.
