vo=gpu-next
hwdec=vaapi
gpu-api=opengl

big_smile That was it!
I don't get it why vulkan video decoding wouldn't work on my rig (RX 460 Vulkan 1.3)

Vulkan is ok but not with mpv.

so I've to use
vo=gpu-next
hwdec=vaapi
gpu-api=opengl

VAAPI hardware encoding is available on a more limited set of Radeon gpu's according to the same web page.

VA-API is - as far as I know- hardware acceleration using Intel-Graphics.
There is a warper for nvidia GPUs for VA-API calls (nvidia-vaapi-driver).
No idea how or whether this is possible with Radeon graphics.

Just to be sure, I also tested using:

mpv --vo=gpu --hwdec=vaapi

I searched: https://gitlab.freedesktop.org/mesa/mesa/-/issues

and filed my findings under the report:

https://gitlab.freedesktop.org/mesa/mesa/-/issues/12528 "HW accelerated video playback causes VCN timeout"

After several days of building mesa-git and the Linus git head kernel, I appear to have working VA-API acceleration under mpv and Firefox.

The anti-climax was that no obvious commit appeared to fix the issue, just ongoing code clean-ups.
