I think mayhem’s pessimism on this has rubbed off on me sorry haha. This seems to happen periodically, this is the recent UK version: https://www.gov.uk/government/publications/uk-i...

Just seems like something Spotify (etc) could fix in a minute if they wanted to, but there’s no $$$ for them in making sure the right people get paid

aerozol: MB could solve most of the problems raised in that document. and I love how they beat around the bush and talk about "open solutions", but fail to address the only open solution that is clearly visible. the marketing game by the labels is *strong*.

rassami and I had a field day with that turd of a doc and rassami really went to bat to push an article lambasting it, but once again, we got zero traction.

^ I think mayhem meant to tag you Lotheric

Lotheric: the industry doens't want better metadata. it might cause them to have to pay the right people the right amount. something they loathe to do today.

given that we had CDDB in 1998, and now literally a quarter century later we're still manually adding metadata... something tells me there's a commercial force actively working against usable metadata

Ding! The industry has spent countless millions to prevent this from happening

see also how two decades has brought us zero dvd databases

is there a standard for disc ID for dvds yet?

its less about the standard then... actually making a project happen. there have been 2-3 attempts, but they never reached critical mass

kepstin: derwin: I can not alter the term. and the alias workaround is also not applicable here. It is "HammerKing" and i can not find the Artist "Hammer King" with that term. Even with fuzzy search HammerKing~0.1 i can not find it. I wonder why, because the distance is just 1.

relaxoMob: the way the search index works, it's a big edit difference separately between "HammerKing" and "Hammer" and between "HammerKing" and "King"

Ah okay. Then i can not do anything I think. Thought it was more like Levenshtein Distance.

@mayhem is there a way to start such a thing for dvd / bluray in *brainz ? I have a backlog of ~300 DVDs and 10 blurays to add to it immediately, and I'm a software engineer who's happy to work on this now.

@relaxoMob if you take the search query as a sentence, the hamming distance to "Hammer King" is 1. If you take it as separate words, neither of them match very well.

what about the shasum of /VIDEO_TS/VIDEO_TS.IFO (or .BUP, they're identical) ?

we've had the domain moviebrainz.org registered for... a really long time. so, there is room to start such a project under our umbrella. if you're good with using python/flask/postgres, you'd inherit a massive amount of infrastructure for hosting the new site on our setup.

but as of right now, we can't dedicated any personnel resources to it -- we're always on the knife edge of the budget for hiring engineers. and that happens when more supporters sign on.

nope, I'm a C++ person

that's a sad mismatch of skillsets. :(

I know. I can read all the DVDs and blurays with my code? :-)

fun fact of the day: it was my boss who forgot a step in the DVD encryption process that caused DVD Jon to break the DVD encryption algorithm.

but I might be dating myself now, lol.

nice!

I think that makes you at least slightly older than me

mayhem: That was a major landmark, and you were there!

indeed. I was at Xing and did a double take when I heard they had an mp3 encoder. the only other one in existence from what I knew. and they knew not what they were sitting on.

Xing, isn't that the people that also made Ogg?

thing is, DVDs aren't that different from CDs. They typically contain one track of relevance, but can contain more, the tracks have a length etc.

(kudos to Disney for putting 142 hours of video on a single dvd - according to the toc, at least)

didn't Microsoft have a DVD ID of sorts used by their Windows Media Centre?

dascandy: dvd structure is a lot more complex than cd structure tho - there's titlesets, which have titles, which have chapters, and the programmable menus can make the individual user-visible programs be anything from a few consecutive chapters within a longer stream (common on tv series dvds) or combine parts of multiple individual titles; iirc there's even been some with random sequencing so you get a different experience each time :(

and yeah, the structure allows multiple titles to refer to the same blocks on the disk, which has been used for drm purposes by making simple extraction tools expand the disk to use way more space.

making an id to identify a disk is, well, easy enough. Making one that works like musicbrainz disc ids where it provides useful information about the lengths of tracks… not really.

cds can be a bit more complex than the musicbrainz disc id format really covers - tracks can have multiple indexes, but the disk id only uses the INDEX 01 positions for each track (which is the place where a cd player will seek to if you ask it to start playing a specific track)

discid is a hash of the track info. Nothing that you can derive back to track lengths, just an ID. Same for mbid, just an ID (but random in this case)

there's a BD ID used for keydb.cfg indexing which is the sha1 of /AACS/Unit_Key_RO.inf

and you *could* use the disc name... but for the one I have now (A Few Good Men) the disc name is "LOGICAL_VOLUME_ID"

most of the time though, dvds or blurays contain a movie or episodes of a series. You *could* code Zork with the scripting the language allows, but most of the time it isn't used for that and just used for playing a movie.

new standard allows N weird things, most use only uses basic functionality, some players only support basic functionality, everything's adjusted to the least common denominator, and the rest is just fluff in the spec

see also Red Book cd-text and graphics

(did you know your music CD has space for animated graphics! Nobody uses it and nothing supports it, but it's in the spec!)

@minimal there was such a thing, but the whole DVD support has been ripped out of Windows so I don't think it's relevant any more

heck, new bluray drives have been made to actively refuse to work at all when you insert a uhd bluray
