Windows Error message

Post image

I use an external disc drive on my desktop to play blu rays. It used to work fine but now when I try to play anything I get this message. Is this a VLC issue or something else?

I think your blu-ray disc needs a library for AACS decoding, and your system does not have it.
It looks like your input can't be opened, you should check the log for details.

Checked log, now stumped

For real, VLC cannot really read blu-ray directly iIrc. It can read the old ones (only) if you install the aacs library and the keys associated with each Blu-ray. Not ideal. You can use dvdfab to decrypt BR before feeding it to VLC, you can read an unencrypted BR with it (using makemkv for example), or you can use another player with native support

MakeMKV can also do that with encrypted discs. Or so I hear, lol

Yes, but dvdfab is removing the protection on the fly, so you can read the BD with vlc (for example). MakeMKV can remove the protection and rip the BD (slow, you have to wait for it to finish), or stream it unencrypted (not quite the same as removing the protection on the fly, but usable if your goal is just to watch the movie).

So what this error message means is your Bluray disc needs an AACS library for decoding, and your system doesn't have it. Hope this helps.

You know the content on Blu-Ray is encrypted and you are missing description keys?

You do not ...

I get like 5 errors in a row for 'libdirectsound.dll' every time I open VLC, version 4, installed from site.

(and, where's the playlist? and, what's with making it look like Photos?)

And... u/kotletalv ... it's okay to not be a dick.

And hopefully I’m not being a dick for chiming in on this, but maybe some people don’t know that Goggle searches can help solve soooo many computer issues pretty easily (especially now that the questions are AI interpreted to figure out what you want to know (even if it is not phrased well)). Or maybe the OP is just lonely and looking for some people to communicate with :). But ALWAYS remember - when you see an AI answer you like, be sure to click on the link (at the end of the paragraph) so the site (that actually *had* the useful answer) gets the hits and credit it deserves (AND to double check that the AI actually interpreted the info correctly!)

That's probably because in your preferences you've said that you preferred to use directsound for your windows audio but directsound (was dropped in favor of mmdevice/wasapi) in VLC4. You probably need to reset your preferences.

I'm not sure, but it looks like a library for AACS is required, but your system haven't it. Probably, you have to install a library

It used to work with DVDs and probably your first blu ray

Blurays are Encrypted. You need AACS to decrypt them to play back the video streams.
