Just a quick question to clarify. What Kodi version should be installed on 64-bit dietpi when choosing it from dietpi-software?
I am asking this as the Kodi website states that the newest version for Rpi OS is Leia 18.7) but the one that I have installed is Kodi from Debian 17.6.
When I check for updates, I am getting all up to date:
root@Kodi:~# apt-get update
Hit:1 https://deb.debian.org/debian buster InRelease
Hit:2 https://deb.debian.org/debian buster-updates InRelease
Hit:3 https://deb.debian.org/debian-security buster/updates InRelease
Hit:4 https://archive.raspberrypi.org/debian buster InRelease
Hit:5 https://deb.debian.org/debian buster-backports InRelease

Why is that?
Am I missing some repository?
Kodi is installed from official Debian repository. Hence it is 17.6 on arm64
https://packages.debian.org/buster/kodi
As the version from Raspberry Pi OS is still for 32-bit only 
.
I found the solution on the kodi forums: https://forum.kodi.tv/showthread.php?tid=348014#:~:text=Got%20it%20sorted,v3d%2Ccma-265
Got it sorted with adding the cma-256 to the driver overlay line in /boot/config.txt, so it looks like this:
dtoverlay=vc4-fkms-v3d,cma-265
This did it for me. Rpi3 b 64bit.
theoretically, in meantime Debian Bullseye Kodi19 should be working fine on RPi4B 64bit
Sorry. I remembered wrong. This fixed it for me on my pi 3b board. Haven’t tried it on my pi 4 yet.
usually it should be working on a RPi3 as well.
Would be great if you could test it with the DietPi v7.9 beta: https://github.com/MichaIng/DietPi/issues/5019
It uses the Kodi build from the RPi engineers on all architectures now and on RPi 4 a CMA size of 512 MiB is applied to support 4k playback. For 60 Hz, an additional config.txt setting is required: https://www.raspberrypi.com/documentation/computers/config_txt.html#hdmi_enable_4kp60-raspberry-pi-4-only
