DietPi OS for Quartz64

[MichaIng]

Any hints on how to get hardware accelerated HD video working? It seems that one should at least be able to play H.264 1080p videos, if not 4k, with the hardware acceleration available on the RK3566. As it is out of the box MPlayer and VLC are not set up to use any hardware acceleration and so can't even play 720p video properly. Are there any relevant packages that I need to install and command line switches/configuration set up to use on any of the usual media players to do it?

The Mali G52 should be supported by Mesa drivers, and the latest entry in changelog for this GPU is from v22.3.y, which is shipped by Debian Bookworm: https://packages.debian.org/source/bookworm/mesa

Which graphics API are MPlayer and VLC using (or supporting)? In case, mesa-va-drivers (VA-API) or mesa-vulkan-drivers might be needed. The basic KMS/DRM/EGL libraries should have been installed together with the X server.

If this all does not help, you could try our Trixie image, where Mesa 23 and newer video player packages are available: https://dietpi.com/downloads/images/
