Hide multiple versions of same movie

[Thalhammer]

Describe the bug
If a movie is added in multiple versions it shows up multiple times in the search/list ui.
All versions with the number of version in the top corner.

System (please complete the following information):

• OS: Ubuntu 18.04
• Virtualization: LXC (Proxmox VE 6.2)
• Clients: Browser; Android
• Browser: Chrome 83
• Jellyfin Version: 10.5.5
• Playback: None
• Installed Plugins:AudioDB;Fanart;IPTV;MusicBrainz;Playback Reporting;Reports
• Reverse Proxy: none
• Base URL: none
• Networking: Direct via Linux Bridge
• Storage: NFS to VM on the same VM Host (FreeNAS)

To Reproduce

1. Put movies with the same name + version postfix in mediafolder.
2. Let it scan them
3. Go through media collection and group duplicates
4. View Media List/Search for title

Expected behavior
The Title shows up once, with both versions available when opening the details.

Seen behavior
The title shows up twice, both with the indicator for multiple versions and clicking on any of them
shows the version selection (So it definitly understood that they both belong together).

Logs
Screenshots
See below

Additional context
I do not have both movies in a folder named after the movie as I would need to move a lot of files and would break other software accessing the library. However I have all movies in a single folder and group them manually through the ui.
I am not sure if this is a bug or the intended behavior, but it is intended, I believe there should be an option to hide those duplicates on the UI (which I could not find anywhere).

Yes, this has been happening for quite some time, would be nice to have a fix for this.

[Thalhammer]

I do have experience with C# / Javascript development.
Any hints on where to start if I where to try fixing this myself ?

[anthonylavado]

This is mostly inherited behaviour, which we haven't changed. I think there's already a proposal to auto identify qualities and group them that way, using the codec/quality as the identifying marker.

I don't know where you'd work on this though - it would need implementation in the server and in the web interface, then the clients, etc...

[Thalhammer]

I don't think you'd actually need to change the clients, I think it would be enough to remove the duplicate item from the list returned when listing movies.

[anthonylavado]

You're right - I was confusing this with the logic to select a version to playback as well. Anyway...

[Thalhammer]

@holow29 I dont think so. The issue you linked is about individual files not getting group automatically. My issue is about the files still showing up as two titles after being grouped manually (both with the group marking), where IMHO the gui should only show one entry for the group.

[holow29]

@Thalhammer you're right. I think the issues are similar in that they deal with grouping of different versions malfunctioning but not the same.

[danieladov]

This only occurs when grouping movies into collections is enabled

[Thalhammer]

It still exists....

[iFloris]

@Thalhammer this can be mitigated somewhat by using the mergeversions plugin; we use that and it works well, even for separated HD/4K libraries.

It feels like #5324 should have fixed this, but for me the issue still persists. I am using version 10.7.0 from docker (jellyfin/jellyfin, not the linuxservers one).
I also tried ungrouping and regrouping some movies, which did nothing.
@iFloris I dont care if I have to manually group them (I dont add new media that often and when I do, converting takes way more time than grouping them afterwards), the issue is that even grouped they show twice pretty much everywhere.

[cvium]

#5324 is slated for a 10.7.1 release fyi

[Thalhammer]

Fixed by 10.7.1

@Thalhammer

It is not entirely fixed. If two individual non-collection movies are grouped there is no problem now, but if those movies are inside a Collection they are shown twice like before the fix. See pic.

Please, re-open the issue.

[Thalhammer]

Sorry, did not know that.

[1024mb]

To update: Even with movies that aren't in a collection the issue is still present. I'm using 10.7.5 (Jellyfin says 10.8.0).

[BugFixesAndPerformanceImprovements]

As a suggestion: make this a toggle in the dashboard as having movies display for each duplicate file is a handy way to spot them in (very) large libraries.

[Lakeland97]

Same issue here

[halictuz]

Same here. Even the correct naming on the folders/files doesn't seem to work correctly. They just don't group as one. Though... if I have two versions of a Movie and I click on the group option they actually have the drop down menu to choose from both versions. This works. But they still show up as seperate entries/movies in the Library and Collections.

[1337haXXor]

I didn't want to create a new issue, because I believe it's the same. Here's my setup:
Movies
└── Donnie Darko (2001) [4K] {Arrow}
└── extras
│ └── Special Feature 1.mkv
│ └── Special Feature 2.mkv
├── Donnie Darko - [Theatrical].mkv
└── Donnie Darko - [Director's Cut].mkv

I performed a rescan, but I have twice the problems. The movie is displaying twice in the library with no dropdown option. Additionally, all of those special features are showing in my movie library, which indicates to me there's a problem with the naming. When I FIRST migrated my library to accommodate jellyfin formatting, I had a few movie folders with the year first (1940 - Fantasia), and I noticed that all the special features, even when in an "extras" folder, showed up in the library. But when I fixed the root movie folder name, the extras worked properly.

So I guess there's something with the naming? I tried changing the folder to remove the [4K] and {Arrow} tags and did a rescan after each, but still nothing.

EDIT: Well, I figured out why it was messing up the structure. I read randomly on another comment, that the file names have to match the folder name, THEN the extra bits go after hyphen. So that's cool. Why does it have to be this way? For individual movies, I can have:

Movies
└── Zatoichi(2003) [DVD] {Miramax}
└── Zatoichi.mkv

And the file name doesn't have to match the folder. But with multiples, I have to add all my folder tags into the file name, like this?:

Movies
└── Donnie Darko (2001) [4K] {Arrow}
└── extras
│ └── Special Feature 1.mkv
│ └── Special Feature 2.mkv
├── Donnie Darko (2001) [4K] {Arrow} - [Theatrical].mkv
└── Donnie Darko (2001) [4K] {Arrow} - [Director's Cut].mkv

I'm glad I got it working, but this doesn't seem ideal.

[GodTamIt]

I have another use-case that seems to break as well.

Example for TV:

TV/
  Breaking Bad (2008)/
    Season 01 - 1080p /
      Breaking Bad (2008) - s01e01.mkv
    Season 01 - 2160p AV1/
      Breaking Bad (2008) - s01e01.mkv

Currently, this results in two entries for each episode in Season 1. Instead, we should just group them together.

[Shadowghost]

Multiple versions are not supported for episodes so this is expected.

[xenago]

This would be a great feature. It's baffling that the scanner can identify two files as being the same film but does not combine them

[nickspacemonkey]

There is a workaround for this on reddit: https://www.reddit.com/r/jellyfin/comments/11o3nwa/how_to_handle_multiple_movie_versions_and/?utm_source=share&utm_medium=web2x&context=3

Although there seems to be some contention as to whether or not this is a bug, or if people are not following the naming conventions correcty.

I don't think thats the same issue. The issue here is that despite the movie/show being grouped (i.e. jellyfin correctly knows its the same and lists the versions in the movie details page) it still shows two entries for this movie. It seems to be fixed since 10.7.1 for the main views and I can't verify the collections issue because I don't use collections.

[xenago]

It's definitely still a problem in the main release in the main library sections. It will still match multiple copies of the same item and not combine them:

It ought to be fixable, since the scanner is correctly matching the films, just not combining them (even though the files are all being matched to the same exact film in TMDB).

This plugin seems to do it, so presumably something like it could be added:

@xenago Please give your file structure

[xenago]

File structure is irrelevant to this issue (if a specific file structure is required beyond simply placing each movie in a folder, then that needs to be fixed as well since JF is currently able to match each file just fine), each of the films is matching to the same TMDB ID and therefore should be combined since JF is completely aware they are the same. I used the plugin for now until this is fixed properly.

All that is required here is for the scanner to check if an item already exists when scanning, and to combine rather than add as a separate entry. I am struggling to understand how this has not already been implemented when the plugin exists.

[Thalhammer]

It's definitely still a problem in the main release in the main library sections. It will still match multiple copies of the same item and not combine them:

Thats a separate issue though. This issue was about grouped items showing multiple times, not about same movies not being automatically grouped, which while still a bad thing is less of an issue IMHO because you can just manually group them.

[Bond-009]

@Thalhammer Is right, and I haven't really seen examples of the original issue since the fix so I think this issue can be closed?

[rodhfr]

for me the issue was there (i'm using linuxserver docker container) but as commented above this plugin solved:
https://github.com/danieladov/jellyfin-plugin-mergeversions

[saberblaze]

One thing I don't think I've seen mentioned is that when there is a movie with 2 versions in one folder that also has an extras folder, the extras folder is not picked up by Jellyfin. The movies shows up twice in the library but no extras are shown. If I follow Jellyfin naming guide with identical names and dash at the end, the extras do show up. The mergeversions plugin avoids having to rename hundreds of files however the Jellyfin bug that prevents the extras from being picked up is present regardless of wheter the plugin is used or not. I'm not sure if opening a new issue is warranted or if it all falls under the same umbrella.

Ideally, it would be nice if Jellyfin can incorporate the mergeversions plugin functionality to avoid duplicate entries in the library and in collections while also making sure that the extras folder is properly picked up when there are multiple movie versions present.

[tromphakvoort]

I had the same issue with episodes where I have a low quality version and a high quality version, the plugin mentioned before did the trick. https://github.com/danieladov/jellyfin-plugin-mergeversions
