hate to bump this thread, but anyone have any luck with hardware decoding in latest Armbian? Tried with 26.5.1 vendor kernel with both gnome and kde. None of the guides seem to work with hardware decoding. Tried the above posted fork as well, but seems 26.6.1 doesn't ship with g610-g24p0-wayland-gbm. Installing it from here just gave me a black screen at boot.
Not sure what else to try, I had moonlight working with hardware decoding in 24.8.1 a couple years ago here.
