To fix this problem, use my build from :[7.95.beta5] LibreELEC 8.0 builds for KI Plus / KII Pro
If is same as kszaq's only adding support for internal dvb tuner. Also install tvheadend42 + pvr.hts from this post.
kszaq: I have two differences in my build:
1. Amlogic I2C support is necessary for internal dvb driver;
2. I had issue with patches to compile latest media_build. To fix it I temporary deleted media_build-02-add-to-backports.patch
Hi afl1, wich device tree should we use? I'm trying with device_trees without succes.
regards, Jefken.
and thanks to the hole community for all the help... Im new in that arm based Kodi scene and read the threads with a lot of attention. My first Kodi version (love at first sight) was an alpha version on the xbox with nothing more that one Gui Screen and a list of Videos you can choose - thats it
