Playback

Preparation

Firstly install libaacs, aacskeys and libbluray-git (/usr/share/java/apache-ant/bin must exist in $PATH while installing libbluray-git).

(Optional) Get KEYDB.cfg from http://forum.doom9.org/attachment.php?attachmentid=11170&d=1276615904 and unzip it into ~/.config/aacs/. Then run
sed -i 's/\([[:xdigit:]]\)\{5,\}/0x&/g' ~/.config/aacs/KEYDB.cfg"
Next, mount the bluray to a directory. eg:
# mount /dev/sr0 /media/blurays
Now the bluray has to be added to the key database so that libaacs can decrypt it. To do this, cd into /usr/share/aacskeys and run:
aacskeys </bluray/mount/dir>
eg:
cd /usr/share/aacskeys && aacskeys /media/blurays

Edit ~/.config/aacs/KEYDB.cfg and add the information outputted by aacskeys using this syntax:

0x<unit key file hash> = Film Title    | V | 0x<volume unique key>

mplayer

To play blurays in mplayer you will need mplayer-bluray installed.

The basic playback command is:

mplayer br:///</bluray/mount/dir>

Troubleshooting

Stuttering Video

It is likely that you will need to enable hardware acceleration and multi core CPU support for the bluray to play smoothly.

For nvidia cards, enable hardware acceleration by installing libvdpau and using the option '-vo vdpau' with mplayer. eg:

mplayer -vo vdpau br:///</bluray/mount/dir>

For multi core CPU support use the options '-lavdopts threads=N', where 'N' is the number of cores. eg:

mplayer -lavdopts threads=2 br:///</bluray/mount/dir>
Incorrect Audio Language

You can scroll through the playback languages using the '#' key.

Out of Sync Audio

From your first mplayer output, you must find the codec used for the bluray. It will be at the end of the line "Selected video codec".

For H.264 discs use the option '-vc ffh264vdpau'. eg:

mplayer -vc ffh264vdpau br:///</bluray/mount/dir>

For VC-1 discs use '-vc ffvc1vdpau'. eg:

mplayer -vc ffvc1vdpau br:///</bluray/mount/dir>

For MPEG discs use '-vc ffmpeg12vdpau'. eg:

mplayer -vc ffmpeg12vdpau br:///</bluray/mount/dir>

vlc

Currently vlc only supports bluray playback in development versions, so you will need to install vlc-git.

Start playback with:
vlc bluray://</bluray/mount/dir>

Other Useful Software

For DVD, the libdvdcss package supplies the needed decryption libs. Below are some options for BluRay/HD-DVD decryption. Users can employ to backup a commercial BluRay movie under Fair Use guidelines:

  • anydvdhd - Commercial software requiring users to run it on an Microsoft OS in a VM.
