“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.

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.
