Try running vainfo from libva-utils directly on KMS console like /dev/ttyv0.
If it prints a list of supported formats you can proceed with mpv e.g.,
$ mpv --no-config --hwdec=vaapi --gpu-context=drm /path/to/foo.mp4
or
$ mpv --no-config --hwdec=vaapi --gpu-context=displayvk --vulkan-display-plane=2 /path/to/foo.mp4
(if --vulkan-display-plane=2 doesn't work check --vulkan-display-plane=help output)
then toggle stats via keybinding
$ man mpv
[...]
i and I
Show/toggle an overlay displaying statistics about the currently
playing file such as codec, framerate, number of dropped frames
and so on. See STATS for more information.
and look for "(hwdec: vaapi)" substring one "Video:" line.
