Blu-Ray equivalent of Gracenote/CDDB?

[mukiex]

So CDDB/FreeDB used CD track times/counts in order to get a "fingerprint" of an individual disc, making it easy to rip your own CD and automatically fill in the proper metadata (track names, CD composer/singer, track numbers, etc.).

Is there anything like that for Blu-Ray? I mean, the mpls files that litter the

Code: Select all

BDMV/PLAYLIST

folder have track and timecode data, so wouldn't it be possible to get a disc-specific fingerprint from those files? Given how few CDs have collisions on track length/order, it would probably be near-impossible for two Blu-Ray discs with different movies to have the same MPLS arrangement. And that's assuming you can't get the UPC/serial info from a disc, which for all I know you can.

Anyhoo, just curious to know if this is something that already exists.

There have been some efforts towards this sort of solution, but...

Lionsgate single-handedly has made it difficult at best - a single DVD or BD title can have dozens of variations, each with a unique signature, due to rotating fake playlists. Sure, there would be few collisions, but "Ender's Game" (for example) would have several dozen different entries.

unless multiple versions of the disc have different disc IDs (and therefore different VUKs) then it shouldn't really be a problem.

The same CD was released with multiple different releases and gracenote/cddb handled it ok.
