The vid is not the only thing makemkv needs for discs it doesn't already have a VUK for. There's other data in the discatt.dat that is also obfuscated that makemkv needs to generate a VUK. That's the whole point of the tar.gz dump files that are sent to makemkv. This whole thing is pointless anyway....

You can also validate a Media Key by checking whether MK (x) VID generates a VUK that can successfully decrypt the Unit Keys. This assumes that the TGZ contains a kv.dat to validate the Unit Keys against, of course.

Yup you can. My code does not.

You'll need to zip up and link the MKB_RO.inf file in the AACS directory for that disc.

Unless the Media Key for that disk is already known?

I'm sure it is but you have to have the MKB_RO.inf to validate that assumption.

Or the data is obfuscated intentionally for a reason.... Which it is.

It won't work. They are not "transferable" even if you "update these 4 items." I don't get it. If I can synthesize a discatt.dat for one disc from that of a different disc, and they are exactly the same as if I had generated the file with MakeMKV, what wouldn't work? I don't und...

Look at the source code if you want to see the format. But knowing the format isn't going to help you. You can't just create one.

That's the latest but make sure you go back and read the release notes for R1 and R2, as well. avdvplus did a LOT of work on Dolby Vision.

EDIT: Fixed the link...accidentally posted the same R3 link again.

You can install that to get CoreELEC installed but then I would use this: https://github.com/avdvplus/Builds/releases/tag/avdvplus_R3 Basically once you get CoreELEC installed, you put that tar file in the update folder, reboot, and then check the settings, CoreELEC menu to setup your Dolby Vision o...

Nice. Mine just shipped. Can't wait.

My tool will tell you the status of your discs and keep the makemkv copy of the keydb up to date. Since you're on windows it could be useful.

TvOS supports it on the Gen 3 Apple TV. So they do support hdr10+ when they want to.

It's not. I was able to get to it just fine.

Thanks, that was helpful.
Now also supported.
