Running LibreElec in Armbian
The purpose is to run KODI from LibreElec in Armbian with most of features available, especially HDMI CEC. The only reason for me is that building KODI with features enabled is not an easy job. I have no security concern.
Please follow Armbian official user guide to install Armbian to your hardware. For RK3399 hardware, I would recommend you install latest version with legacy kernel.
This step may be optional for other hardwares. If HDMI CEC is not important for you, you can also skip this step. By default, legacy kernel (4.4.x) does not have CEC driver enabled. We need to change default config to enable kernel module and rebuild kernel. No longer required for latest legacy kernel for RK3399 based boards!
Follow Building Armbian to build and replace kernel.
I did not do tests wihtout wayland drivers. Not sure if this step is optional.
sudo apt update
sudo apt install xwaylandDownload LibreElec image from LibreElec. I use legacy kernel image for RockPro64 for NanoPC-T4. Run bash command to build rootfs. During execution of this script, you will be prompt for password for sudo.
./build-rootfs.sh LibreELEC-RK3399.arm-9.2.6-rockpro64.img.gzThe commands below are just for you to verify KODI's functionality. More work need to be done to make KODI a service startup with system.
mount --bind /dev rootfs/dev
chroot rootfs /bin/bash /start_kodi.shYou may mount folders with media files into rootfs so that files can be
accessed. You could also modify the start\_kodi.sh script to add your
mouns.
By far, I use this command to start KODI.
unshare --mount-proc -p -f -r -R rootfs/ /start_kodi.shSimple systemd file examples are put in folder systemd. You need to edit the
those files and install the libreelec.service in systemd. Besure to change
environment ROOTFS to correct path.
This solution works quite well for me. Hardware acceleration works as well as HDMI CEC. H256 HW decode also works.
