Hi Igor, Thanks for getting back to me.
Could you tell me more about what do you mean for?
I've installed a lot of them, so I'll list them for you:
Celluloid, a bit jerky, cpu not stressed
Dragon Player, doesn't work the application is running but when I select the files it doesn't open them
mpv media player, jerky, cpu more stressed celluloid
smplayer, the best, but struggles again in 4k
vlc media player, worst, cpu 100%
I'm hoping that at least one of these is compatible with the type of video acceleration I need.
So are you saying that KDE Plasma with Wayland can't use the processor to be rendered?
