I think I passed that with the fix below, still building though.

If you run Chromium on from the console, did you observe any logs that were related to VA-API? Make sure you *DO NOT* use "--use-gl=egl".

That makes no sense as 160 and 163 were just security related releases. Only culprit could be the recent mesa updates imo.

That's the wayland fix, we don't need it for M81 now, it is already there.

My build was done, unfortunately VA-API is busted for M81 and required further analysis of what changed. This is going to take some time.

Both NVIDIA and Intel showed the same error. Xorg/Wayland does not matter. But for Intel, "--use-gl=egl" is also busted, that means Wayland busted for i965 VA driver. This is a pretty bad regression, unfortunately.

Agreed, might try reverting back to i965 mesa driver as iris is now the default? Though this may not work either per @liewkj's post above.

As for me, I've decided to move over to Firefox (using nightly) as I can reliably have it working with Wayland and also VAAPI enabled hw accel (though it seems less performant than Chromium? (based only on the comparisons of percentages shown using intel_gpu_top))

Try --use-gl=egl flag.

The lag is happening to me without that flag, but not with it. Anyway I'm using an older Radeon card.

Re: chromium: hardware video acceleration with VA-API

Flag "--use-gl=egl" is broken and it is broken on the official build without use_vaapi=true, too. So this means VA-API on Wayland is totally busted for Intel GPUs for both i965 and iHD VA drivers.

I use radeon driver, updated to linux 5.6 and new chromium-vaapi version. Now I see that --use-gl=egl isn't working and removing the flag I have lag on 1080p60 videos inside the browser.

Tried also to downgrade chromium-vaapi, the flag is working, but the lag on 1080p60 is showing the same.

Maybe I can try to downgrade the kernel, but I don't want.

youtube-dl, streamlink and mpv is da way.

Upstream Chromium bug confirmed.

Hopefully, next release for Chromium will resolve the "--use-gl=egl" bug and have video decode acceleration restored for Wayland.

Yes, it is a serious regression for Vega, I don't have any problem on my desktop with an RX590, don't know if the culprit is the kernel, mesa, libva or xf86-video-amdgpu, I'm getting frustrated by this hardware, 'cause again neither suspend or hibernate works too.

Yeah it is really frustrating for me too. Since the last 3 versions of the kernel and the last 2 upgrades to mesa and chromium, hardware accelleration works for some videos (h264) and not for others. Since today (kernel 5.6.6) i'm having lag even with youtube videos at 720p 60 fps.
If i run chromium from the terminal and try to open this video i get this errors:

mesa: for the --global-isel-abort option: may only occur zero or one times!
mesa: for the --amdgpu-atomic-optimizations option: may only occur zero or one times!

By inspecting "statistics for nerds" in youtube video it shows that many frames get dropped whenever the video lags and blocks
For the hibernate issue i can confirm that too and it's really frustrating because i always have 8 virtual desktops setup and i usually never shutdown so i need to reset all my workflow each time these things don't work.

Re: chromium: hardware video acceleration with VA-API

I finally found the issue with VA-API on Wayland, especially for Intel GPUs that have to take the EGL code path for VA-API to work in Wayland session. My previous workaround was to downgrade xorg-server-xwayland to 1.19.7. That is no longer required and it works fine with the official xorg-server-xwayland package from Arch repo, at the time of writing 1.20.8-2. It turned out that upstream xwayland was just fine, Chromium simply required a reliable platform methods for predicting v-sync. When not taking the EGL code path. the GLX extension GLX_OML_sync_control provides the GetVSync() and GetMscRate() function for Chromium codes that try to predict v-sync. This is the GLX code path and it is the default for Linux build.

When taking the EGL code path, Google defined EGL_CHROMIUM_sync_control provides the equivalent for GetVsync() but no GetMscRate(). The later is provided through ANGLE which is a cross-platform conformant Open GL ES implementation by Google in its own extension EGL_ANGLE_sync_control_rate. So when GetMscRate() returned false, the codes fallback to an approximate calculation to predict v-sync.

In chromium-81.0.4044.138/ui/gl/sync_control_vsync_provider.cc:116

  int32_t numerator, denominator;
  if (GetMscRate(&numerator, &denominator) && numerator) {
    last_computed_intervals_.push(base::TimeDelta::FromSeconds(denominator) /
                                  numerator);
  } else if (!last_timebase_.is_null()) {
    base::TimeDelta timebase_diff = timebase - last_timebase_;
    int64_t counter_diff = media_stream_counter - last_media_stream_counter_;
    if (counter_diff > 0 && timebase > last_timebase_)
      last_computed_intervals_.push(timebase_diff / counter_diff);
  }

  if (last_computed_intervals_.size() == 2) {
    const base::TimeDelta& old_interval = last_computed_intervals_.front();
    const base::TimeDelta& new_interval = last_computed_intervals_.back();

    double relative_change =
        fabs(old_interval.InMillisecondsF() - new_interval.InMillisecondsF()) /
        new_interval.InMillisecondsF();
    if (relative_change < kRelativeIntervalDifferenceThreshold) {
      if (new_interval.InMicroseconds() < kMinVsyncIntervalUs ||
          new_interval.InMicroseconds() > kMaxVsyncIntervalUs) {
        // For ChromeOS, we get the refresh interval from DRM through Ozone.
        // For Linux, we could use XRandR.
        // http://crbug.com/340851
        LOG(ERROR)
            << "Calculated bogus refresh interval=" << new_interval
            << ", last_timebase_=" << last_timebase_

            << ", last_media_stream_counter_=" << last_media_stream_counter_
            << ", media_stream_counter=" << media_stream_counter;
      } else {
        last_good_interval_ = new_interval;
      }
    }
  }

Perhaps the approximation was tuned based on xwayland-1.19 branch and I guess it broke when xwayland-1.20 branch added multi-buffering support that changed how drawable surfaces were flipped. Hence, we got logs storm of "Calculated bogus refresh interval" errors.

So a workaround is to use XRandR APIs to obtain current refresh rate in place of the ANGLE-specific EGL extensions on the EGL code path.

This is not an ideal fix though as EGL code path should be free of any X11 binding APIs. We have no choice because there isn't any alternative methods available from MESA OpenGL ES implementation to do the same. I wish to be corrected if anyone more experienced with OpenGL ES can shed some lights on it.

Re: chromium: hardware video acceleration with VA-API

The clean solution is for MESA EGL to implement EGL_ANGLE_sync_control_rate.
Bug filed https://gitlab.freedesktop.org/mesa/mesa/-/issues/2930

Once MESA EGL added the implementation, the following Chromium issue is resolved, too. Both Intel (i965, iHD) and MESA VA-API drivers (r600, radeonsi) work equally great on both X11 and Wayland session regardless of GL backends.

The error sounds like you would also have issue with vainfo. Please check if vainfo is also reporting initialization error.
Did you compile your own chromium to enable vaapi?
It will also be helpful if you can show the command line of how chromium was started. You can get the information from chrome://gpu in the row of "Command Line".

No, you don't have to unless you have access to powerful multi-core build machine. Otherwise it may take days for anything less than a quad-core and 8GB RAM.
However, it would be nice that you also show me the build you sourced from so that I can try it out, too. I have proposed 2 fixes to AUR chromium-vaapi, but they are meant for Wayland. I don't expect those issues to apply if you use X. You can find them in the message area of the AUR package.

In the meantime, I can only recommend that you remove the `--enable-native-gpu-memory-buffers` flag or just keep the `--ignore-gpu-blacklist` and remove everything else for debugging.

The oldest Intel GPU I can check is a Sandybridge Celeron 847 laptop. The GM45 is obviously a very old platform, but as long as vainfo looks fine it should work, especially for H.264.

Already running for 24hrs. :-) Let's see if it will finish (2/3rd from build)

Yes, I see it. I use the chromium package from the archlinuxcn repository: https://github.com/archlinuxcn/repo

I am sorry I overlooked your vainfo details. Your VA driver is missing `VAProfileNone` which is required by chromium-vaapi. Outside of chromium, mpv and gstreamer-vaapi may not require it if their VA-API support was designed around libva <=2.0.0.

Re: chromium: hardware video acceleration with VA-API

Hi all, not sure if this is a VA-API related issue but I strongly suspect so; with the NVIDIA proprietary driver installed and KMS enabled, I encounter occasional display problems (familiar blurred window) and very occasional spontaneous exits. There are no errors printed if I start Chromium from a terminal. I tried disabling KMS and the problem seems to have gone away.

Anyone experiencing the same issues with KMS-enabled NVIDIA driver?
