the traditional way for doing disc ids for dvd is to just do an md5 hash of one or more of the info files in the filesystem, iirc

i imagine something similar would work for bd

keep in mind that DVD and Blu-Ray are both just computer filesystems (UDF) full of files, they don't really have a structure with "tracks" etc.

Reading title/chapter/etc. requires parsing some files on a dvd; for identification a simple hash is easier.

Standard Title ID might work well for many, many disks

particularly since title/chapters/etc in the dvd structure don't really match up with the user-visible dvd contents, since it's all done with menus and programming.

not sure what you mean by "title id", the filesystem label?

kepstin definitely has some dvd sets where the filesystem label was set wrong one one disk, so two disks in the set have the same label

I thought the disc format had an id string at least for movie type discs, seems I'm wrong, at least on bluray.

the disk filesystem itself has a label string, which is what shows up when you e.g. put the disk in a computer
2016-07-07 18956, 2016
kepstin
but that's just entered arbitrarily by the person who mastered the disk, so it's meaningless and not unique
2016-07-07 18942, 2016
kepstin
(many DVD and Blu-Ray backup software can copy the disk contents to a folder on your HD, which means this filesystem label string is lost completely)
2016-07-07 18901, 2016
kepstin
although they normally use that label to name the folder, at least by default :)
2016-07-07 18952, 2016
kepstin
oh, huh, I'm wrong for DVDs at least, the name is also in the VIDEO_TS.IFO file
2016-07-07 18922, 2016
modwizcode
Ah so I was correctly remembering that.

but yeah, if I was making and ID to use to lookup a DVD, I'd use a hash of the VIDEO_TS.IFO, or maybe a hash over all the *.IFO files.

might be a bit complex for DVDs, I dunno if you have to authenticate to the drive before you can read those off a physical disk :/
2016-07-07 18947, 2016
modwizcode
No DVD is pretty simple I think
2016-07-07 18902, 2016
modwizcode
Pretty sure those are all laid bare since they are used to identify which files to play
2016-07-07 18944, 2016
kepstin
hmm, until a player has authenticated to the drive, the drive will reject read attempts on the DVD with an I/O error
2016-07-07 18949, 2016
kepstin
kind of annoying, really
2016-07-07 18919, 2016
kepstin
but if you can mount the disk, it's easy; if you can play it with some other player, then you can read the files afterwards just fine :/
2016-07-07 18906, 2016
modwizcode
Pretty sure authenticating the drive is not a problem.
2016-07-07 18924, 2016
kepstin
hmm. it must be something like that, tho.
2016-07-07 18950, 2016
kepstin
if I try to read a disk before starting a dvd player on it or using a libdvdcss app on it, it gives IO errors rather than data :/

chirlu: on our side, rsync is running and accessible locally, but i can't access to rsync from the rest of the world, prolly this port is blocked by the firewall in front of ours, i'll ask DWNI to check

i see nothing wrong on our side, i suspect the DWNI firewall because we had such issues (unaccessible services from outside) before
