You can directly play homemade/burned and unprotected Blu-ray discs with VLC. But for commercial Blu-rays which employ several DRM mechanisms such as AACS and BD+, VLC requires the decryption key data base and AACS dynamic library to play these encrypted Blu-ray discs. Without these, it cannot access the encrypted data on the disc, and thus displays the "This blu-ray disc needs a library for AACS decoding error" message.

In this following page, we've concisely listed the necessary steps to help you play encrypted Blu-ray discs with VLC on Windows and Mac. Please note that an external Blu-ray drive is necessary for playing Blu-ray on computer.
