Hi,
Yes. If you are playing encrypted Blu-ray discs, then you’ll need AACS keys. We’re not allowed to distribute them, but they can be downloaded as follows:
mkdir -p /home/osmc/.config/aacs
wget https://vlc-bluray.whoknowsmy.name/files/KEYDB.cfg -O /home/osmc/.config/aacs/KEYDB.cfg
You may wish to use a cronjob to regularly update the list of keys.
Cheers
Sam
