Jellyfin not updating metadata

[twodragonsrob]

Recently upgraded to 10.9.1 (on Debian bookworm) and noticed that metadata was not updating/being added if I use "Search for missing metadata", "Replace all metadata" or "Identify".  It does appear to work if I am adding a new video using "Scan for new and updated files".

In trying to troubleshoot, I changed a title and then ran "Replace all metadata", which should restore the original title.  The only lines that relate are (time stamp removed):

I've scanned through the forum and have been unable to find a similar thread.

Try changing the folder name. All the DVDRIP and XVID stuff is possibly throwing off the identification process.

You can also try removing the folder, scanning, putting the folder back, and then scanning again. I've had to do that if metadata gets "stuck" or whatever. Nothing in the log to explain it.

Thanks TheDreadPirate, however it's not that specific file, it's all files - I just tried on another movie, and same result (changed movie title from "Margaux" to "Marg" and ran refresh all with no result). And these are files that ran perfectly prior to my upgrade.

While it isn't too much of a problem with movies, it's a real problem for my porn library where virtually every new item needs to have its metadata updated manually, using the Porndb plugin (and I've checked that that's working).

This appears to be related to decisions made for https://github.com/jellyfin/jellyfin/pull/10339 - metadata appears to be being pulled and then sometimes stored in movie.nfo, regardless of whether {filename}.nfo files exists. This kinda kind works if you have different versions of the same movie in the folder, but really blows when the folder contains 'Abby Lee Brazil.m4v', 'Megan Rain.m4v', 'Roxy Raye.m4v' and 'Veronica Avluv.m4v', being 4 scenes in a split scene porn movie. In the past, I have treated the 4 scenes as separate, then combined into a collection named for the movie title.

Can someone please provide a solution that doesn't mean that I need a folder for *every* scene, or do away with scene metadata altogether?

You can use the "part" naming scheme for movies.

I'm not sure how flexible the naming scheme is. "movie - scene-part1.mkv" or something like that. Note that there is no space between "scene" the dash and "part1". IIRC, Jellyfin is particular about the movie parts syntax.
