Bought an Azulle Inspire for my dad with an i3-7100U and 4K playback is choppy in Kodi. Running Linux Mint 18.3. Any tips for how to fix it?
Have you enabled any sort of hardware acceleration?
I haven’t messed with kodi in ages, but I know 4K playback can be achieved on a raspberry pi, so I can tell you that this is a configuration issue.
All hardware acceleration options in Kodi are enabled.
DISCLAIMER: I take no responsibility for what you do on your own system. This is what worked for me.
Add unstable Kodi repository and upgrade to Kodi 18
sudo add-apt-repository ppa:team-xbmc/unstable
sudo apt-get update
sudo apt-get install kodi
Upgrade Linux kernel to Linux 4.15.0-13-generic
sudo apt-get install linux-image-4.15.0-13-generic
Add apt-key to download intel-linux-graphics-installer in Mint
wget --no-check-certificate https://download.01.org/gfx/RPM-GPG-GROUP-KEY-ilg
sudo apt-key add RPM-GPG-GROUP-KEY-ilg
Fake lsb-release to report Ubuntu so the installer works.
