Different metada languages within the same library

[makako48]

Is it possible to have different metadata languages for different profiles within the same library?

for example, when trying to set up my mom's profile she needs to have everything in spanish

Or I just make a new library with the same folder but this time in spanish? but idk if that'll mess up the images, my subtitles, etc.

The problem is that you can't have the same folder in two different libraries, IIRC. But if you create a symlink of that folder you can get around that.

Because to do what you want you will need to create a separate library and set the preferred download language to Spanish. I've never tried this, but I'm assuming that will tell Jellyfin to pull down metadata in Spanish when it is available.

Then in Dashboard > Users > select your mom's user, you can set it so that she only see the libraries with Spanish metadata.

I now have managed to set different metadata language within the same library by setting the respective flag in the database (when you have an unique identifier in the title of the movie eg.):
1. stop jellyfin
2. backup database: /var/lib/jellyfin/data/library.db
3. sqlite3: update TypedBaseItems set PreferredMetadataLanguage = 'de' where Name like '% (DE)%';
4. start jellyfin
5. set: Dashboard -> Libraries > Libraries > ... > Manage Library > "Automatically refresh metadata from the internet" to true/30 days
6. wait and enjoy
