Identification issues

[TheDreadPirate]

Excuse me, but I read online that a few years ago it was possible to manually modify the regular expressions (regex) for content identification. Is this information correct or inaccurate?

If it were correct, I wonder why this functionality was removed. Perhaps it could have solved my problem, and I believe it might be useful for many other users as well.

If this was ever a thing, it hasn't been since I've been using Jellyfin (Feb 2023 with 10.8.10).

As far as you know, are they actively working on this? Or is it currently on hold, waiting for other higher-priority tasks to be completed?

Not that I'm aware of.  Currently the biggest efforts are the EFCore library database migration, allowing external database providers, and HDR to HDR transcoding.

TWO WHOLE DAYS spent manually fixing unrecognized content... and today when I checked again, everything was back to square one! So frustrating! I wasted four hours of my life for nothing!

Do you have NFOs in your library? The only two circumstances that would cause manually changed metadata to revert are having NFOs in your library or "replace all metadata" library scans.
