Part 3: Errors and Fixes for VLC Won't Play Blu-ray

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.
  • • This blu-ray disc needs a library for aacs decoding, and your system does not have it.
  • • No valid processing key found in AACS config file.
  • • Missing AACS configuration file!
  • • Your input can't be opened.
  • • VLC keep Blu-ray loading but nothing presents.

This is because not all the commercial Blu-ray discs are supported by VLC media player so that you might encounter the problem from time to time. VLC can only deal with discs which its library has the corresponding AACS keys, yet the AACS and BD+ DRM libraries and keys won't ship with the Blu-ray discs, as their publishers seem to take everyone as a pirate, even you already spend money just for personnel movie enjoyment.

Fixes for VLC Won't Play Your Blu-ray Movie

1. Using Another Blu-ray Player

VLC is not necessarily the best option, but if you're a heavy VLC user already, it's at least an option. Perhaps a better, also free, method is the Leawo Blu-ray player application. It also supports DVDs, and while you're not paying for it, you're only getting a very basic Blu-ray player. Nevertheless, it's reliable and gets the job done.

If you're interested in something a little more feature-filled, there are numerous apps out there. The best is Cyberlink's PowerDVD 19 ($80 at amazon). It offers support for 3D Blu-ray as well as regular discs, high frame rate playback, HDR, casting and 4K UHD Blu-ray.

2. Digitizing your Blu-ray Collection

If you're looking for something a little less intensive or simply want to digitize your collection, there are many available apps for you. One of the best options is DumboFab Blu-ray Ripper. It has the ability of backing up Blu-ray/DVD to multi-track MKV which can store multiple video/audio tracks with all meta-information and chapters. And it can also rip BD/DVD movies to MP4 and MOV with multiple audio streams. This is an unique feature that most Blu-ray ripper softwares that don't provide.

Besides the multi-track outputs, DumboFab Blu-ray Ripper also has the ability to convert Blu-rays into virtually any popular video and audio format such as H.265, H.264, MP4, MOV, MKV and AVI. If you don't know what settings to use, not to worry, as there are more than 200 pre-configured device profiles to choose from. Additional tools include split, trim, slip, merge, adding audio and subtitles, and snapshot, among others.

The process of ripping Blu-ray using DumboFab is simple and straightforward. Pop in your Blu-ray disc, choose an output profile (e.g. H.264, MP4, or HD MP4.), and click Convert. Then go get a cup of coffee (conversion takes time).

If you still own Blu-ray discs, with the above steps you will be probably able to play Blu-rays with VLC. If you failed to play your Blu-ray discs using VLC and cannot find the exact reason and solution, just turn to another Blu-ray player or digitizing your Blu-ray collection for enjoyment. Having your DVDs and Blu-rays ripped and stored on a hard drive or NAS box can be an absolute joy. Just click, play, and start watching. Moreover, after ripping, you can play them on more portable devices or media players. And it's not a bad idea to keep your physical discs from scratching, or manage your movies in a more convenient way.
