Have a look at our Rockchip sub-forum. Seems like LE currently has some issues on OPi 4 LTS.
I think Ubuntu runs fine, and you can autostart Kodi from Ubuntu.
So that's the workaround until LE issues are fixed.
Thanks that saves me time and money. With 4 other Libreelec in use around the house I would like to keep them all the same. From what the sub-forum is saying there is issue with HEVC x265. Most of my collection is x265 so maybe this will not work for my needs.
Is there any board (that I can hide behind my TV) that does work as well or better then the Raspberry 4 does out of the box?
