@mars Still unable to work, only able to work under X11.

--enable-hardware-overlays is not needed anymore and --use-gl=egl is required in my test.

Is it still working? It's not working for me with intel Integrated Graphics.

Its not work

In my test, the 104.0.5112.79 version maybe the final vaapi workable release for wayland Qzoneplatform.

The recent releases both of 105 and 106's vaapi trigger only be succeed for x11 session, and even for x11 there're laggy gpu render problem and video decoding laggy problem for that.

On my Intel Coffeelake (Gen9) on intel-media-driver/ Nvidia Pascal Optimus system with the DGPU disabled I can't get vaapi with vulkan enable, however it works with these flags:

--enable-features=VaapiVideoDecoder,VaapiVideoEncoder
--disable-features=UseChromeOSDirectVideoDecoder
--ignore-gpu-blocklist
--enable-hardware-overlays
--enable-oop-rasterization
--enable-raw-draw
--enable-gpu-rasterization
--enable-gpu-compositing

Is chromium working for you? for me is not even launching on manjaro compute(may be its needed to wait only)

@hedgepigdaniel Thanks for the info. Unfortunately, the patch seems more like a preparation to support VA-API on wayland and it does not work for me. Could you share your flags if it works for you?

@emilss @nihil21 Extra flags may break VA-API support. On my machine, enable vulkan make VA-API unavailable although about:gpu page still show Video Decode: Hardware accelerated. Try remove all flags in your config and add the flags you actually needed. Make sure VA-API work with X11 first, then add the flags for native wayland support.

@mars you may want to update this to use the more up to date patch here: https://chromium-review.googlesource.com/c/chromium/src/+/3646633
