HW on chromium-vaapi with xf86-video-ati/libva-mesa-driver

Had anyone made this work yet ? All the information I find online is for intel cards and last time I tried I could not get it working even with ignored gpu blacklist.

I have no clue why the hacky vaapi patches floating around require separate handling for Intel and non-Intel, because there's no Intel specific code in Chromium.

Anyway, your best bet is trying the official patch that will land in Chromium soon™: https://chromium-review.googlesource.com/c/532294. The patch adds a new compile option, so you need to add 'use_vaapi=true' to _flags in the PKGBUILD. Then after Chromium is compiled, you need to enable hardware decoding in chrome://flags. I haven't tested the patch yet, I'll wait until it actually lands in Chromium, and I can test only Intel anyway.

My machine is not able to withstand the heat generated from compiling chromium. I guess I'm going to have to also wait or hope some Trusted User picks up chromium with the official vaapi patch.

There's chromium-vaapi-bin in AUR, however it uses one of the unofficial patches. And I just found out there actually is Intel-specific code in Chromium, currently Chromium specifically loads the Intel VAAPI driver. But the official patch removes that code. The person maintaining chromium-vaapi in AUR is aware of the official patch, but doesn't seem sure if he should switch to it, see last comments here: https://aur.archlinux.org/packages/chromium-vaapi/. Maybe write a comment there that this patch possibly enables VAAPI also on drivers other than Intel.

Works fine for me both with Intel graphics and AMDGPU.  Try going into chrome://flags and enabling video acceleration.
