Great software. Use it. :)

See: for key

See for CLI instructions.

Your API key needs to be set in ~/.MakeMKV/settings.conf

app_Key = "app-key-123"

To backup into directory “test”:

makemkvcon backup --decrypt disc:/mnt/bluray/

That will decrypt and dump the entire disc, in original M2TS format.

Backup main titles to MKV

Note that it won't take a symlink to the block device.

makemkvcon mkv dev:/dev/sr0 all .

Another option:

makemkvcon mkv disc:0 all .
