NAME¶

bluraybackup - Tool to backup Blu-ray Disc Movies (BDMV)

SYNOPSIS¶

bluraybackup [-d device] [-k keyfile] [FILE] [DEST]

bluraybackup [-d device] [-k keyfile] -m [DEST]

bluraybackup [OPTION]

DESCRIPTION¶

bluraybackup backups Blu-ray Disc Movies (BDMV), inspired by dvdbackup, developed in ANSI C (C89) following the suckless philosophy.

It makes a decrypted copy of the whole Blu-ray Disc Movie or it extracts a decrypted version of a specific BDMV stream.

This program may not work with all Blu-rays. It both depends on your KEYDB.cfg file and on the BD+ generation (version).

To successfully decrypt a Blu-ray Disc Movie you both need libaacs installed and a KEYDB.cfg file, containing your disc keys.

Moreover, if your disc is plagued by BD+ as well, you need to install libbdplus. BD+ is a form of copy obstruction, which consists in writing video streams to disc with small errors. These errors get fixed during playback by a virtual machine embedded in official players, only if the player keys are verified by the same virtual machine. libbdplus is an implementation of the BD+ virtual machine features. However it doesn't support all the BD+ generations. Since libbdplus 0.2.0, it's possible to bypass BD+ emulation, using cached tables to fix the broken streams.

OPTIONS¶

-d, --device device

defines Blu-ray disc device (default /dev/sr0)

-h, --help

-k, --keydb keyfile

defines keys database file path (default $HOME/.config/aacs/KEYDB.cfg)

-m, --main

USAGE¶

bluraybackup [-d device] [-k keyfile] [FILE] [DEST]

Without FILE, the whole disc will be copied to the current directory. FILE must be a file path relative to the disc root.

Without DEST, the decrypted FILE will be sent to standard output. DEST path must include file name.

bluraybackup [-d device] [-k keyfile] -m [DEST]

Without DEST, the main disc title will be sent to standard output. DEST path must include file name.
