Mecool KM9 pro (S905X2) amlogic HW acceleration

Hello,

I try to find some solution for my box. I installed version 21.2 to my box (g12a_s905x2_2g.dtb), but when I switch on the amlogic acceleration then 4K mkv files doesn´t play. Even most of full HD mkv doesn´t play.
Then I installed 20.5 and then 19.5 and similar results. I hear audio (all codecs through AV receiver) but black screen. Videos up to full HD mkv work well without amlogic acceleration.
Could someone help me? :unamused:

Tomas

Nobody knows?

Using coreelec 20.5 I can play videos, but I see black screen. Only sound is going.

Nobody will know because the times of using glass bowls are long time over…
