Re: chromium: hardware video acceleration with VA-API

I'm getting following message spammed when running in a Plasma Wayland session using intel modesetting (i.e. no xf86-video-intel) with both the intel-media-driver and the libva-intel-driver:

--enable-zero-copy

#Additionally --disable-gpu-driver-bug-workarounds has been tested and confirmed to remove video freezes (especially when watching in fullscreen).

#https://bugs.chromium.org/p/chromium/issues/detail?id=879929
#--use-gl=egl

Any ideas?

Yeah for me vlc, mpv and smplayer all work with e.g. x264.

Re: chromium: hardware video acceleration with VA-API

FYI, intel-media-driver has a bug with fast forwarding videos in H264 format, VP9 works fine.

Re: chromium: hardware video acceleration with VA-API

Someone knowledgeable might explain the details, but I can assure you I have the same, and yet HW acceleration works, the CPU usage is definitely smaller, intel_gpu_top is showing correct output, and video playback is nice and smooth smile

Have you tried the any of the following flags:

?

I have this being reported too, except I'm using Brave Browser and I think the Brave team have removed some of the flags that Chrome/Chromium accepts, including these.

[9744:9744:0217/183821.262913:ERROR:vaapi_wrapper.cc(1149)] : Failed syncing surface VA error: internal decoding error

YouTube videos using either VP9 or H264 show (intel_gpu_top from intel-gpu-tools) shows that the video decode part of the graphics card is active, and so is the 'video-improve' (whatever that is). With the i965 driver, the video-improve section is always at 0%. I'm assuming this is a new feature/capability of the media-driver vs the old libva-driver.

Either way, CPU usage is still much higher on Linux than on Windows or macOS (no matter whether using i965 or iHD). Using the same Chromium build on Windows 10, watching a 1080p YouTube video in VP9 or H264, gives CPU usage of around 2% to 3%. Under Linux, the same YouTube video with the same settings uses 12% to 15% CPU. That's a huge difference; especially when you consider that's >6x more resources of a 12 thread 5GHz CPU doing the same task.  neutral Is this simply what we can expect due to driver abilities? Or is this a Chromium (and/or vaapi patch) issue? Could something else be tweaked?

Edit: A word.

Have you tried the any of the following flags:

https://peter.sh/experiments/chromium-c … deo-frames
https://peter.sh/experiments/chromium-c … ry-buffers

?

I have this being reported too, except I'm using Brave Browser and I think the Brave team have removed some of the flags that Chrome/Chromium accepts, including these.

What GPU are you using, 'once'? If it's integrated Intel graphics then software memory buffers is normal and expected (see the Intel GitHub repo for intel-media-driver).

Re: chromium: hardware video acceleration with VA-API

Hey guys,

If you are moving from `aur/chromium-vaapi-bin` with Intel KabyLake+ CPU, and use `aur/intel-media-stack-bin` as your VAAPI driver, please note that you may need to uninstall `aur/intel-media-stack-bin` first as it offers VA-API 1.3 and this chromium build needs at least VA-API 1.4

You should use `community/intel-media-driver 18.4.1-1` instead, and trying to the following contents into `/etc/profile.d/intel-media-driver.sh`:

```
export LIBVA_DRIVERS_PATH=/usr/lib/dri
export LIBVA_DRIVER_NAME=iHD
```

So that after set the correct flag of chromium, you could enjoy your VAAPI-enabled chromium now.
