VK_MESA_video_decode_av1: Early Vulkan AV1 Decoding For Open-Source Radeon Driver

[geearf]

I'm not sure ACO is involved. Does it rely on shaders? I thought video might be a different case from graphics.

Plus I think in some longer term, ACO will be hooked up for radeonsi too.

But in general - yeah. If llvm can be avoided, it's better for more timely bug fixes potentially.

Hmmm, good question. I use shaders with mpv, but maybe it has nothing to do with hw dec.

mpv uses shaders for some filters / scaling and etc. It's unrelated to usage of VAAPI.

That's why there are two parameters, one for hwdec=vaapi and one for vo=gpu + gpu-api=opengl / vulkan.

Speaking of mpv - Debian finally packaged shaderc. I'll try building mpv with Vulkan support now until Debian will catch up and update the mpv package.

Thank you!

No dice. Packaged shaderc isn't compatible with mpv now due to missing symbols and glslc. I guess Debian developers need to untangle that mess.

libshaderc.so.1: undefined symbol: _ZTVN8spvtools5utils5TimerE

Similar issue was reported on Arch years ago: https://bugs.archlinux.org/task/63720
