I'd do it in a 'simplier' way, just use a new uSD card, that is partly a benefit of SBCs running on uSD cards.

Thanks for your feedback. But as I wrote, it looks like hw accel works in general when checking the much lower CPU load vs. the fps. CPU 4x100% => ~10fps HW 1x20% => ~6fps Thats why I think the VPU really gets used but not optimal. btw. I did not yet get mpv to work with frambebuffer. T.

Short GPIO PIN13 and PIN14

You probably have to replace base-files package.

Orange pi zero 3 with 1.5g had the same problem too.. I think they used the 1.5g hardcoded patch to fix it. You might have to remove the newer ram size detection patch. I haven’t updated warpme patches in awhile so I’m hoping this bug has been fixed.
