I have tested rk3568-eflasher-debian-bullseye-desktop-5.10-arm64-20230210 and this is my opinion.

Chromium youtube hardware acceleration works ok.
Smplayer not work ok. Videos don't show image.Mpv the same.Vlc works but with bad performance.
Kodi 19 is not ok and not recognize properly the hardware graphics and cpu usage is very high.
Desktop is nice than buster image but video programs not work properly.
I will stay some time until corrected errors on buster image because kodi 17 and video players and Chromium youtube works ok.
