armbian nanopi m4v2 rk3399 mali t864 not working

[Giuseppe93]

Hello Armbian community,
I am writing this topic because, despite the drivers for the processor's integrated GPU are installed within the operating system, they do not seem to work properly.
Precisely the system seems to work but as soon as I try to play a video it is played by the CPU and not by the GPU with lag and the CPU is at 100%.
I leave the link and the attachment of the result of the armbianmonitor -U command that I posted here:

it is a compressed tar.gz file since I included all the results of the command

You need a video player that supports video acceleration. Mali support works as otherwise you would not be able to run Wayland.
