chromium: hardware video acceleration with VA-API

uncharted · 2023-05-25 18:14:28

I am able to get hardware accelerated video decoding working on my laptop in X11 environment with the integrated AMD Radeon GPU. The issue is I am not able to get this working on my other GPU.

from brave://version

Brave: 1.53.66 Chromium: 114.0.5735.35 (Official Build) beta (64-bit) 
Revision: 2295354895fa3652ae47b651481831484f16d1ff-refs/branch-heads/5735@{#713}
OS: Linux
JavaScript: V8 11.4.183.8

I used the following flags to get it working on my integrated GPU

 --ignore-gpu-blocklist --enable-features=VaapiVideoDecoder,VaapiVideoEncoder,VaapiVideoDecodeLinuxGL,VaapiIgnoreDriverChecks --disable-features=UseChromeOSDirectVideoDecoder,UseSkiaRenderer

This is from my brave://gpu in both of the GPUs cases

 Video Acceleration Information
Decoding
Decode h264 baseline
16x16 to 4096x4096 pixels
Decode h264 main
16x16 to 4096x4096 pixels
Decode h264 high
16x16 to 4096x4096 pixels
Decode vp9 profile0
16x16 to 8192x4352 pixels
Encoding
Encode h264 baseline
321x241 to 4096x2304 pixels, and/or 30.000 fps.
Encode h264 main
321x241 to 4096x2304 pixels, and/or 30.000 fps.
Encode h264 high
321x241 to 4096x2304 pixels, and/or 30.000 fps.

The driver information section is a bit weird because it keeps saying that the "active" browser is always the gpu0 (it's the integrated one), even after switching GPUs. The hardware decoding also doesn't work in the case of the dedicated GPU; I confirmed it with the media-internals tab as well as the media section in devtools.

This is the output when launching browser just normally

This is the output when launching it with environment variable `DRI_PRIME=1`

These are the details of my GPU

On my steam deck(AMD APU), laptop(Intel APU) with Wayland on 113 version (current) no combination of flags/env vars works, let's see how it will be in the next release
