Blu-ray Playback

No official Blu-ray player software exists for Linux, but open-source libraries allow Kodi (on LibreELEC) to play most Blu-ray discs once /storage/.config/aacs/KEYDB.cfg has been populated with a flat-file database of known encryption keys and certificates. To avoid legal issues with DMCA laws in the USA we cannot pre-configure a key database, so you must install this yourself.

Connect to your LibreELEC device via SSH, then run the following commands:

mkdir -p /storage/.config/aacs
curl -k -L http://fvonline-db.bplaced.net/fv_download.php?reduced -o /storage/.config/aacs/keydb.zip
unzip /storage/.config/aacs/keydb.zip -d /storage/.config/aacs/
mv /storage/.config/aacs/keydb.cfg /storage/.config/aacs/KEYDB.cfg
rm /storage/.config/aacs/keydb.zip

The current file contains PK, HC, VUK and UK data required for attempting disc decryption with more than 170,000 titles. Periodically running the commands will refresh the KEYDB.cfg file and add support for new Blu-ray discs.
