“This Blu-ray disc needs a library for aacs decoding, and your system does not have it.” You read this because you got a Blu-ray error when trying to play a Blu-ray disc with VLC Player on your computer. VLC is a good player software for Blu-ray content on Windows, macOS and even Linus, but it still can’t play Blu-ra disc that protected by aacs or BD+ nonetheless. Therefore, if you want to enable VLC to play those commercial Blu-ray discs, you must find the valid library for aacs decoding and put it into the right place, so that VLC can invoke it for decrypting Blu-ray content.
More Errors that you May Got when Playing Blu-ray with VLC
What is AACS? AACS is short for Advanced Access Content System which is a standard for DVD and Blu-ray content distribution and digital rights management. Accordingly, with the protection of AACS, all unauthorized access to the DVD and Blu-ray content will be banned. And that is the reason why you cannot play the Blu-ray disc on VLC. Luckily, many AACS decryption keys have been extracted and published on the internet, enabling decoding the AACS protected DVD or Blu-ray Media with third-party software such as VLC. So those extracted decryption keys are the library for aacs decoding that you need when playing Blu-ray disc with VLC.
Where to download AACS decoding library and how to install it to VLC
To fix “this Blu-ray disc needs a library for aacs decoding…” error, there are two files that you need to implement to your VLC.
- KEYDB.cfg file – this file is used by aacs decoding file.
- libaacs.dll – this is the aacs decoding file
Step 1 Go to vlc-bluray.whoknowsmy.name, you will receive the privacy error telling you that Your connection is not private. Click on the Advanced button to enlarge the error explanation tab and click Proceed to vlc-bluray.whoknowsmy.name (unsafe).
Step 2 Download keys database file and AACS dynamic library file onto your computer. You should download the right version of AACS dynamic library according to your system. Since I am in Windows 10 60bit, so I will download the VLC 64 bit on Windows version.
Step 3 Install the downloaded files.
For Windows:
- Put KEYDB.cfg in
C:Users[Your User Name]AppDataRoamingaacs. You can press Win + R to launch the Run application, and enter %appdata% into the Open text filed. Then click OK to open the directory of C:Users[Your User Name]AppDataRoaming, then Create a folder name “aacs” and copy the cfg into the folder. - Put libaacs.dll in your VLC installation directory.
For Mac:
- Put KEYDB.cfg in
~/Library/Preferences/aacs/(create it if it does not exist). - Put libaccs.dylib in
/usr/local/lib/directory (create it, if it does not exist).
Note: since vlc-bluray.whoknowsmy.name has been out of update for years, so please follow our instruction to install those files.

Errors You May Encounter When Playing Blu-ray in VLC
Even you have successfully installed VLC 3.0 or above and follow all the steps above, you likely still encounter errors like:
• This blu-ray disc needs a library for bd+ decoding, and your system does not have it.

So, the problem that 'VLC won't Play Blu-ray' is difficult to fix. But, in this case, a more powerful Blu-ray player software comes as an alternative to play Blu-ray on Windows and Mac computer.
