[Modified Solution] How to Play Blu-Ray with VLC Media Player on Windows

Author by Kevincy Berel

Feb 27, 2020

VLC Media Player is presumably the default media player on many people's computers. It is so popular not only because it is free and cross-platform, but also has powerful decoding and playback capabilities. In addition to being able to play common DVD, CD, Video CD, SVCD, with the help of necessary files, it makes it possible for VLC to play Blu-ray discs. Detailed instructions are provided in this article.

Can VLC Play Blu-Ray?

VLC originally did not support Blu-ray disc playback. From the Input Media part on official website, you can see that Blu-ray is not covered. Since 2010, the launch of a project called libbluray made it possible to play Blu-ray with VLC.


However, the libbluray library does not break any DRM, that is, VLC can now play DRM-free and homemade Blu-Ray, but it is powerless for commercial Blu-Ray due to the existence of AACS and BD+ copyright protection. No worries, in the following content, I'll guide you through a few steps to decode and play encrypted Blu-ray discs.

[Revised Solution] How to Play Blu-ray in VLC Media Player?

When you play encrypted Blu-ray discs, the following error messages may always pop up:


- Missing AACS configuration file!

- No valid processing key found in AACS config file.

- This Blu-ray Disc needs a library for AACS decoding, and your system does not have it.

- This Blu-ray Disc needs a library for BD+ decoding, and your system does not have it.

- Your input can't be opened:

- VLC is unable to open the MRL


Even VLC keeps loading Blu-ray but nothing happens. Without further ado, here is the improved solution.

Step 1. Install or update VLC to the latest version for Blu-ray menu support. https://www.videolan.org/

Step 2. Download libaacs and libbdplus DLLs via this link below, and move the two files to corresponding VLC directory.

For 32-bit PC: https://vlc-bluray.whoknowsmy.name/files/win32/, C:\Program Files (x86)\VideoLAN

For 64-bit PC: https://vlc-bluray.whoknowsmy.name/files/win64/, C:\Program Files\VideoLAN

Step 3. Download keydb.cfg file via http://fvonline-db.bplaced.net/, and move it to "C:\Users\YourComputerName\AppData\Roaming\aacs", eg, C:\Users\WonderFox\AppData\Roaming\aacs. Just create an "aacs" folder if it doesn't exist in the subfolder of "Roaming".

Step 4. Now run VLC, go to Media > Open Disc > Disc tab > Blu-ray > Play. You can play your Blu-ray successfully.

Tips: If the error message persists, please try your other Blu-ray discs (both old and new releases/titles). Update the keydb.cfg file manually to keep the key database stay fresh as VLC can only recognize keys from AACS and BD+ DRM libraries and play the Blu-ray. Please wait for the keydb.cfg file update for new released Blu-ray discs.

Sometimes, it may display "Mismatch between disc and player region codes" on the screen of VLC Blu-ray player. So you can follow the steps below to fix it.


Step 1. Click on the Tool menu on the top, then select Preferences.

Step 2. Switch to "All" in the lower left corner to show Advanced Preferences.

Step 3. Navigate to "Input / Codecs", double click on "Access modules" and select Blu-ray. Then you can change the region code on the right side.

Step 4. Save the settings. Now VLC will play it normally.

At last...

Honestly, I have tried several methods on the internet to make VLC play Blu-ray but all was in vain. After I regrouped the steps, it worked for me. I have summarized the possible causes for VLC Blu-ray playback failure:


1. An old version of VLC.

2. Place FindVUK keydb.cfg and .dll files to a wrong directory.

3. Keydb.cfg and .dll files are not up-to-date.

4. New released titles with new encryption.


Just troubleshoot your issues item by item. Hope you guys can play Blu-ray with VLC successfully, good luck!
