No, but the drive of your concern should be fine (ripping with MakeMKV / playing with libmmbd which is really also MakeMKV) out of the box with UHD. LibreDrive is just a requirement for UHD ripping. It doesn't mean that all LibreDrive drives come with a firmware with ...

... maybe its really obvious, but i was just curious about it. I'll just point out that MakeMKV also installs its "VLC integration" library libmmbd.so.0 into "/usr/lib64", where libbluray can find it without any extra configuration. This wouldn't be true if MakeMKV installed it ...

So not giving out the correct VID is a "feature"?

Yes, I think so. MakeMKV's "hashed keys" database is private, and libmmbd only exists to integrate with libbluray-using applications like VLC etc. You'll probably find its aacs_get_mk() function is equally unhelpful...

..., hence why I'm certain libmmbd's implementation is incorrect. I think you'll find libmmbd is behaving exactly as designed. The problem is just that you are expecting its aacs_get_vid() function to return the disk's VID, whereas I think ...

... the same time (in sequence, one after the other, not both at the same same time ;) ) is just a case of using dlopen/dlsym, although i tried using libmmbd exclusively and the same issue arises, hence why I'm certain libmmbd's implementation is incorrect.

The result from libmmbd's aacs_get_vid looks like dirty memory. Library might be returning some stale memory instead of the correct value pointer (or a null pointer / null key if not valid). According to the source code, libmmbd's ...
