Hi folks
Although Thoradia addons were dead since 9.2 I found easy way to make it work,
and a tiny mod inside the Radarr and Jacket addon makes it work fine on my LE 12.2 on aarch64 on my RockPI 4.
What u need is to install Entware (https://www.artembutusov.com/libreelec-entware-ng-installation/)
and install my version of addons. I strongly believe that this might work for other Thoradia addons like Sonarr which uses Mono, but for now I only checked these two.
Basically you just need to install icu and libmediainfo package instead of virtual.thoradia-mono-9.2.16 addon:
# opkg install icu libmediainfo
and that's it !!
What I did in both cases is just corrected bin/.ctl script which suppose to download libs for arm64 arch and point them in LD_LIBRARY_PATH before launching main binary.
Feel free to check if they work on Your arm64 non RPI device
