Collections/Playlist management

[Rubén Navarro López]

Hello everyone!

I have two questions regarding collections.

In a previous post, I mentioned an issue with playlists: they are being deleted after a Jellyfin scan. I also commented on this GitHub issue, which I managed to reopen since I'm not the only one experiencing this problem: GitHub Issue #12008.

The main reason I need this to work is that I want to set up something like "Movies of the Week," seasonal recommendations, or similar curated lists. Playlists would make this very easy, but for now, they aren’t working for me.

In my setup, I have enabled the option to display collections instead of showing movies separately.

First question:
Can I use these collections in another library with a custom title, without moving the media from its original folder?

Second question:
Some of my collections aren’t keeping the correct title. Whenever I try to change them, they revert to the old title after a scan—or I’m not sure why. Additionally, I’ve seen movies appearing in collections where they don’t belong. Removing them doesn’t work, as they get re-added after a scan. I’ve tried enabling the "Block changes" option, but that didn’t help.

How can I achieve my goal without relying on playlists (at least for now)?

Thanks in advance, as always!

There is no workaround for my objective?

For the first issue, if you have networked storage (e.g., a NAS), you may want to disable the scheduled task that cleans up playlists on start. That may be where your items are going. If that's not the issue, please either recreate the issue or grab logs from where it has happened and upload them to privatebin.net while removing any sensitive info.

This doesn't make sense to me. Collections draw from existing libraries. You could go into the Metadata Manager and change the name "Collections" to "Bananas" but it will still draw from your existing library of media.

Check the metadata on the incorrect movies. They may have been misidentified previously and now have a TMDB box set ID which pulls them back in. Deleting this excess metadata should resolve the issue. If not, rinse and repeat what I said above: logs may help to identify what's going on.

Hi! First of all, thank you in advance

1) This is the only info that I can get from logs when playlists are deleted:  https://privatebin.net/?9133736e3ec63145#64raFLB6ByukG5i6hAGX1Rn5CYDyj9SYLRF4kJcDqapx

I do not have the scheduled task that cleans up playlists on start, I saw that and tried out if it's that the problem.


2) I do not know if I explained it properly. I would like to use something like a custom collection, for example, "top movies of the week", and add 10 random movies. Create a new library, for example, "featured films" that is empty, and add the new collection to this library, and make it not visible to any other library than this.

Would be like a Playlist, but as is not working for me, I'm exploring alternatives.

3) I will be checking that, for sure. Do you know where do I have to look in the metadata to check that?

Thanks again!

So the scheduled tasks are set up by default. Look at Dashboard > Scheduled Tasks (at the bottom). Scroll down to the Maintenance section and you'll see "Clean up collections and playlists". The default is to run this at application startup. You can remove that trigger. Network attached storage can create a race condition between Jellyfin boot and network storage existence. Worst case scenario is that it removes your libraries because it can't see the media. Playlists is a small impact of that sort of issue.

   

The log lines you posted indicate the issue may be due to a) a plugin or b) triggered by library scanning. Again, you can find the latter in Scheduled Tasks (see screenshot). For the former, check your installed plugins and share which plugins you have installed.

Hi, I already removed the trigger before writing this posts, same issue.

Attached all plugins that I have.

Is this the culprit?

[Rubén Navarro López]

Nope, this problem is before installing that plugin.

We already talked about permissions on a previous post... what are the needed permissions for users and admin on playlist folder? Maybe I can check it... but I have all permissions for both.

[Rubén Navarro López]

Can I share like advanced logs or something like that? maybe we can find anything there, it's very strange this behaviour

In your library settings did you enable automatic creation of collections?
