I'm unfamiliar with ucvideo, so can't comment on that. You can absolutely clone my github and build yourself. At the moment you would need to comment out the emulators in the "oem" package of your target, but I've been thinking to make it a configurable option like EMULATORS="yes/no".
I've just uploaded new builds, and now I include SABnzbd, Transmission and Sonarr.
To start them do "systemctl enable service ; systemctl start service" in SSH, where service is either "transmission", "sabnzbd" or "sonarr".
Transmission: libreelec:9091
SABnzbd: libreelec:9092
Sonarr: libreelec:8989
Hopefully useful to others who want more from their HTPC's
I've packaged Emby as well, but I'm having some build issues with one of the dependencies for RPi. For Generic it works fine, but after trying it I much prefer Plex. Anybody know if it would be OK license wise to include it in a LE community build?
