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

It clearly says what the problem is. There are links to sites with the solution in this thread on this and the previous page

For VLC playback with libaacs.dll and no other decryptors, you need: * UHD friendly drive, i.e. drive that reads UHD but accepts AACS 1.0 host certificates intended for normal BD (don't know your drive is, if you are lucky there's a hacked firmware available for your drive, check MakeMKV forums) * u...

I don't know then. You need to check libaacs logs to know what exactly goes wrong. Does your setup work for other blurays? Where can I find libaacs logs on Windows? You need to know how to use command line 1. open CMD window 2. set AACS_DEBUG_MASK=65535 3. set AACS_DEBUG_FILE=c:\temp\debuglog_aacs....

I don't know then. You need to check libaacs logs to know what exactly goes wrong. Does your setup work for other blurays?

If there are keys behind it like |U| or |I| it should work. Make sure that your disc matches that discid 0x56954A5EE05A311E0672FA5B74F7296990AD0FB8 = sha1 hash of file AACS\unit_key_ro.inf

Ever stop to think the keydb doesn't contain the key for your disc then?

The keydb requires either
* a disc specific key
* unrevoked drive certificate + unrevoked processing or device key

I don't get how you manage to not see the two long threads on this forum about playing Blu-rays but here's a link with the info you need http://forum.doom9.org/showthread.php?t=176924

libbluray is included in VLC by default

The log above shows there is no key to decrypt the disc in keydb.cfg

Hi, ive just bought a BR player and tried to run a BR disc in it. after reading around apparently i need libaacs.dll and libbdplus.dll, but the website where they are hosted seems to be down and possibly no longer available (https://vlc-bluray.whoknowsmy.name/files/win64/) Does anyone know of an al...

I don't understand the discussion of keydb.cfg and libaacs.dll, but I tried to put them where everyone here says they should go. What I do understand is that I am running VLC 3.0.6 on Win7 64 bit. And before I installed Java, when I played a Blu-ray .iso I got a message similar to "Java is not...

Try setting the environment variable JAVA_HOME to your java dir C:\Program Files\Java\jre1.8.0_201

New issue, when playing any disc from the Star Wars The Complete Saga boxset I get the following problem. The player displays the message, your Blu-ray player requires an update, and I cannot play the discs. I'm using MakeMKV libmmd.dll as my libaacs.dll and libbdplus.dll libraries. Any ideas? I br...

It appears they are in the correct directories. Procmon shows the system is successfully reading libaacs.dll and KEYDB.cfg from the directories. I did see where the system would successfully read KEYDB.cfg from c:/users/evans/AppData/Roaming/aacs/KEYDB.cfg and then try to read KEYDB.cfg from c:\Pro...

"Blu-ray error: This Blu-ray Disc needs a library for AACS decoding, and your system does not have it. Your input can't be opened: VLC is unable to open the MRL 'bluray:///E:/'. Check the log for details." If you see this error it means VLC cannot find the libaacs.dll. Either it's in the ...

OK I signed up at doom9 but can't post for 5 days ...

It will probably be fixed by then

I'm trying to get bluray working with VLC and have downloaded FindVUK 1.20 so I can get the latest .cfg file. When I open a command window and run "FindVUK synchronize" (which I believe is supposed to get the latest .cfg file) I get the errors below. Any ideas? Go to doom9 for questions a...

When I navigate to the site to download the keys, I receive this warning: vlc-bluray.whoknowsmy.name uses an invalid security certificate. The certificate expired on Sunday, August 12, 2018, 11:03:26 PM. The current time is August 23, 2018, 12:23 AM. Error code: SEC_ERROR_EXPIRED_CERTIFICATE Anyone...

follows the tutorial of the beginning but it is not reproducing the disks why is the bd support in vlc so complicated? because AACS LA hates people playing their purchased movies with free software The dlls found here https://vlc-bluray.whoknowsmy.name/ were updated a few months ago and probably wo...

Hmm, this must be disc specific then? I'm paying a Java disc from 2008 without problem using java 8 Region: Tool > Preferences > Show Settings = All > Input / Codecs > Access Modules > Blu-ray You can search the settings when you select "All" in "Show Settings", just enter "...

make sure the environment variable JAVA_HOME points to the correct Java directory , i.e. 64bit java if you use 64bit VLC, 32bit java if you use 32bit VLC

e.g. control panel/system/advanced/environment variables: JAVA_HOME=C:\Program Files\Java\jre1.8.0_161

I see no quotes, neither with the echo %JAVA_HOME% command or SET JAVA_HOME command

goto control panel/system/advanced/environment variables to change it permanently

it works for me (JAVA_HOME=C:\Program Files\Java\jre1.8.0_161). If I change the java_home var I get the same error as you. Since your java_home is pointing to the 64-bit version of java, are you sure you are using the 64-bit version of VLC ?

So, I have tried 2.2.6, and it finds the keys, it finds libaacs, but it doesn't find libbdplus, even though the last one is in system32. I'll see what I can do about that. You can stop wasting your time with libbdplus. Even if you can get it to work, it only supports a few very old BD+ discs (only ...

I tried following the instructions at http://vlc-bluray.whoknowsmy.name/ using vlc 2.2.5 and 2.2.6 using both 32bit and 64 bit versions unsuccessfully and couldn't figure out what I was doing wrong so firstly I'd like to say thank you to candela for putting me out of my misery and letting me know t...

This method does not work at all currently. Currently running Windows 10 Pro and VLC 2.2.5 x64. I went I downloaded the most recent libaccs.dll and KEYDB.cfg as of 5/20/17 and vlc still cannot play a Blu-Ray disc. Still get the error, "This Blu-ray Disc needs a library for AACS decoding, and y...
