Might be some AP incompatibility maybe, I’ve never seen those.
XBMC didn’t have drivers for video acceleration, but the raspberry pi 1 was able to play 1080p flawlessly if you used omxplayer.
Now kodi has the drivers included and the 4 can even play 4k up to certain bit rate.
The new ones are too expensive tho, a used NUC is a much better deal.
Charisma is convincing you to eat the fruit salad anyway.
