Try to play the Blu-ray disc on VLC or other players, but an error window pops up and reminds you of some lines, like “the VLC needs a library for AACS to decode the Blu-ray disc” or any other lack of decrypt package, which lead to the incompatibility of Blu-ray discs and your player.
Then you found libbluray, you can tell from its name that it is a library file for Blu-ray content, which makes you believe you can play Blu-ray with it installed on your player. And, you just failed, or maybe worse, you even have no clue about how to install the package.
So can libbluray help you to get your VLC or MPlayer play Blu-ray?
The answer is NO. Libbluray is a built-in library in the VLC, which is made of navigation, playlist parsing, menus, and BD-J, hence you don’t need to install it to your VLC.
But why is VLC unable to play your Blu-ray disc? That is because most commercial Blu-ray discs are protected by AACS or BD+, while with Libbluray you can only play Blu-ray contents without protection, like some homemade Blu-ray discs.
Therefore, you will need to install the other two files (libaacs file and keydb.cfg) to VLC and make it support playing protected Blu-ray discs.
How to Put a Library File and an Encrypted File in VLC
Libaacs is a file related to decoding Blu-ray media, after adding it to the VLC folder, VLC player will be able to decode the Blu-ray disc.
To smoothly play most Blu-ray discs, you will also need to add an encrypted file (KEYDB.cfg), because most commercial Blu-ray discs are protected by DRM.
Note: This method will take you some time, if you want to watch the Blu-ray disc on your computer, Aiseesoft Blu-ray Player will satisfy you.
Step 1: Download the AACS to VLC’s Location
Open VLC Blu-ray on a browser, then you will find AACS Dynamic Library. Download the files, based on your system type.
Tip: Don’t know if the Windows on your computer is 32-bit or 64bit?
Click the search icon on the taskbar, type “About”, and select About Your PC. Under the Device specifications, you will find System Type, and it will tell whether it’s 32-bit or 64-bit.
After that, transfer the file to the installation folder.
The installation folder of VLC on Windows:
*32-bit: C:\Program Files (x86)\VideoLAN\VLC\plugins
*64-bit: C:\Program Files\VideoLAN\VLC\plugins
The installation folder of VLC on Mac: /usr/local/lib/directory (if you don’t find directory, create it)
Step 2: Download KEYDB.cfg to A Specific Folder
Back to the browser and download the KEYDB.cfg file from VLC Blu-ray to your computer, then move the files to aacs folder.
The AACS folder on Windows: C:\Users\[your name]\Roaming\aacs\
The AACS folder on Mac: ~/Library/Preferences/aacs/ (create it if it does not exist)
Step 3: Play the Blu-ray Disc with VLC
Make sure you have inserted the disc and the driver is connected to your computer.
Open VLC media player, select Media > Open Disc…, choose Blu-ray, and click on the Play button. Then the Blu-ray disc will play in a second.
