[Stadia] Hardware-Acceleration on Vivaldi

Hello there,
sorry i had to re-open a new thread.

This one was closed already

I worked my way through one of the many guides

And i achieved that watching youtube-videos hardware accelerated:

Now i always start my browser via
vivaldi-stable --use-gl=desktop --enable-features=VaapiVideoDecoder --disable-features=UseOzonePlatform
also having the two plugins installed:

  • Stadia enhanced
  • enhanced-h264ify (default only allowing h264 and 60fps)

and the chrome://flags set as described in the several guides.

Everything above is the only combination working for me to achieve hardware-accelerated video decoding on youtube.

But as i start Stadia, Stadia enhanced only shows me

  • “Software H264” if VP9 is disabled in enhanced-h264ify
  • “Software VP9” if PV9 is not disabled in enhanced-h264ify

As you may notice, i dont know much about all of this and just want to play Stadia with good quality.
Does anyhone have a good advice for me what to try?

Little update:
I finally got it working by

  • installing libva-vdpau-driver-vp9-git from AUR
  • starting vivaldi with vivaldi-stable --use-gl=desktop --enable-gpu-rasterization --enable-zero-copy --enable-native-gpu-memory-buffers --disable-gpu-driver-bug-workarounds --enable-accelerated-video-decode --enable-features=VaapiVideoDecoder

But the picture quality is very bad and the latency very high
Screenshot_20211107_161034

First i was happy to achieve this, and i thougt i would now have a very good quality
But the opposite seems to be the case

What am i missing?

OK just to sum it up:

  • For some reason Software VP9 decoding is more responsive for me → Less decoding time?!
  • Also i did not realize, that vivaldi’s tracking blocker caused to slow down my connection → I deactivated it

Now everything is looking much better and the latency is lower and the graphics better
