Had a discussion on #shokofin on discord a while back. I didn't file a bug, but since this has recently been updated, I figured I'd leave this here.

I initially started looking into this when my thumbnails would never show up for new anime... so I started looking into it more.

I'm pretty sure everything is broken out of the box (at least for people who don't use the "auto group" in shoko. Not sure if this applies to people who have the library structured differently).

I did a patch on my own build back in february (disclaimer, I don't know .NET, but I just did some quick googling to figure it out)

+                // if an exact match shows up, use that one.

+                if (seriesIDs is null)

+                    seriesIDs = apiResponse.FirstOrDefault()?.IDs;

                 var seriesId = seriesIDs?.ID.ToString();
 
                 if (string.IsNullOrEmpty(seriesId))

The main problem here is the var apiResponse = await ShokoAPI.GetSeriesPathEndsWith(dirname); which the URL currently ends with /, so you end up searching for /api/v3/Series/PathEndsWith//Senryuu Shoujo (double slash is intentional) for example, and this returns empty because there's no show that ends with /Senryuu Shoujo in my shoko instance.

At least for my case, this patch works perfectly. It simply checks to make sure the name is exactly the same as Shoko (since shoko is also managing the library anyways).

Without the Exact check (but with the / fix), you run into some scenarios that are unfixable even with the "Identify" feature

Eiga K-On! vs K-On! - When you Identify as K-On!, the problem is both of these shows show up in the shoko api. Since Eiga K-On! comes first, K-On! is now impossible to label as K-On!

I didn't want to think I was crazy, So i spun up 2 more jellyfin instances fresh, but using my existing library, 1 using 1.4.0 and 1 using my patched "1.3.1-dev"

No shows appeared on 1.4.0 at all - but 1.3.1-patched showed my shows with the metadata.

I don't think my patch is perfect, but this problem is there and should probably be fixed?

Description

My Jellyfin instance runs inside of a docker container and uses internal dns to communicate with shoko.

e.g.

http://shoko-server.ix-shoko-server.svc.cluster.local:8111

Under advanced settings there is an option to set a public Shoko host URL, I thought this could be used for Shoko links so that they pointed to the correct domain outside the container. However it looks like other traffic is trying to be sent to this domain, rather than just links.

e.g.

[2024-06-10 03:19:07.522 -04:00] [WRN] [23] Emby.Server.Implementations.Library.LibraryManager: Cannot fetch image from "https://shoko.mydomain.com/api/v3/Image/Shoko/Staff/1464". Http status code: null

This domain is not accessible inside of the docker container, because the docker container is not using my LAN DNS server, thus the nslookup fails. http://shoko-server.ix-shoko-server.svc.cluster.local is the domain name it should be using for internal requests (between containers), and it seems this is the domain name that gets used if you leave this blank.

So this puts me in an odd scenario where I can choose to have either the Shoko series links broken or have Shokofin requests fail.

Suggested Solution

An option that causes this domain to only be used for links and not be used for requests to the Shoko server.

Additional Information

No response

Motivation

The TvDB is not always correct, and I don't want to start a VM to use desktop (v1) just to correct a mistaken link if I can avoid it altogether. Also, I try to only use Shoko as a Metadata Provider for Jellyfin, and this do not work out-of-the-box without enabling TvDB as a provider.

Goal

See the episodes you haven't collected yet among the series with only using Shoko as a metadata provider.

To Do

• Add a new API call to get episodes in a series. /api/v3/Series/{id}/Episode already provides IEnumerable<Episode> for us to use.

• Add a new class implementing ILibraryPostScanTask (used to post-process a library after an import), and hook it into populating the missing data if the option is enabled in the library settings. USing a new ExtraMetadataProvider to add extra metadata such as trailers, theme-videos, and metadata on missing episodes.

I have both Shoko and the Jellyfin library for my anime configured with real-time monitoring ("Watch for new files" in the import folder in Shoko and "Enable real time monitoring" in the library in Jellyfin). This usually works quite well as I don't have to scan the whole library when I add new files. Unfortunately, since Shoko and Jellyfin are both processing these files when they are added to the filesystem, Shokofin will almost certainly find no metadata for those files. Due to hashing in Shoko, it practically always takes longer. So Jellyfin will have added the files to the library but without any metadata. To fix this, I have to refresh the metadata on the entire show, after Shoko is finished. If possible, I'd rather have Shokofin wait for the metadata to become available, ideally checking its progress so it can start right after it's finished.

Reproduction

1. Add an import folder in Shoko and configure it to watch for new files.
2. Add a library in Jellyfin that uses the same folder as the import folder in Shoko
3. Configure the library with real-time monitoring and only Shokofin for its metadata
4. Add a new anime series (or episode) to the import folder

Current behavior

1. Both Shoko and Jellyfin see the new files that have been added for the anime series (or episode).
2. Shoko starts hashing it to get the corresponding metadata
3. At the same time, Jellyfin asks Shoko for metadata for that file through Shokofin
4. Shokofin cannot find any metadata for the file
5. Jellyfin adds the file to the library without any metadata
   Steps 3-5 are repeated for every file added.
   This can be fixed by manually refreshing the metadata for the files that were added, after you confirm that Shoko has finished processing them.

Expected behavior

1. Both Shoko and Jellyfin see the new files that have been added for the anime series (or episode).
2. Shoko starts hashing it to get the corresponding metadata
3. At the same time, Jellyfin asks Shoko for metadata for that file through Shokofin
4. Shokofin finds no metadata for that file
5. Shokofin checks whether Shoko is working on that file (repeatedly for a few minutes, as it may take Shoko some time to queue up all the newly added files)
6. Shokofin monitors the queue to wait for that file to be fully processed
7. Once fully processed, Shokofin again tries to retrieve metadata for that file, which should now be available in Shoko.
8. Jellyfin adds the file, with correct metadata to the library
   Steps 3-8 are repeated for every file added.

Alternative

If it's not possible to monitor the queue in Shoko, Shokofin could also just wait a predetermined amount of time before trying to get the metadata again. However, since hashing may take a long time and many files could have been added at the same time, it's hard to predict how long would be reasonable to wait. Because it may also just be the case that Shoko has no metadata at all and is not working on it. In which case you don't want Shokofin to wait at all.

Additional information

With the reproduction, you may run into another problem, with Shoko itself. If you watch for new files in Shoko, it seems to start processing them as soon as the file entry is added to the file system. At this time, the file may still be transferring to the file system. So with large files or slower transfers (like over a network connection) Shoko may be hashing a partially-transferred file. This will obviously not match anything and it will be considered unrecognized. A workaround for this is to first transfer the file(s) to the same disk/partition as the import folder but outside of that folder. If you then move it to the import folder (move, not copy), it should be an instant transfer and Shoko will hash the whole file.

Trying to connect to shokoserver, but no connection could be established.

Running jellyfin in docker, added the repo from shokofin. shokoserver also run in docker. Same ip address range.

Abstract

Somehow link Genres in Jellyfin to Shoko.

To-do

• Find out what the data and how it should map to Genres in Jellyfin.

• Implement a IRemoteMetadataProvider<Genre> to get the information from Shoko.

• Add genres to series/seasons/movies.

I am getting a few duplicates for anime groups that have more than one series.

They have the same metadata and their contents are the same with all of the grouped series.
This is a clean Library with no metadata .nfo and only Shoko is providing metadata.
The anime series are in separate folders. E.g. "Fate/Stay Night" and "Fate/Zero" are in their own folders inside the library folder "anime".

The issue is not to do with actual seasons of an anime, but related series that are part of the same group.

I believe the issue could be jelly/shokofin sees the individual series folders, finds their group and then applies the group information to each series folder.

Any suggestions?

Looking at the list of tags for Shokofin, commit bef066d has ended up being tagged twice with both 2.0.1.40 & 2.0.1.41.

Running git for-each-ref --sort=-creatordate --count 1 --format="%(refname:short)" "refs/tags/" (as per the WyriHaximus/github-action-get-previous-tag@v1 action) currently outputs 2.0.1.40 however, which leads to the next attempt at setting a tag to be the already existing 2.0.1.41...

I'd imagine the easiest resolution would be to manually create tags for 2.0.1.42 & 2.0.1.43 (or just delete the tag for 2.0.1.40) Don't think I can PR anything like this sadly!

I can however, as below, include the git commands to create the tags we'd expect if everything played nice at the expected commits however!

git tag 2.0.1.42 77980cd50fa6ef3d0094886fe0fc00f2acf21e5c

On Jellyfin Web, thumbnails if not available will be replaced by the series poster. But on Jellyfin Fire TV version, they don't get replaced and will be just left blank. I tried looking around for thumbnail generation but it was only for series and movies not individual episodes.

I'm not sure if AniDB provides individual episodes thumbnails so it might not be possible to implement it. If I were to use anilist as metadata provider it will add episode thumbnails, but I'm worried it might trump shoko's configuration.

If you have any suggestions or possible workarounds it would be really helpful.

Thank you.

Abstract

Jellyfin supports trailers items, and trailers may be available locally with metadata stored in Shoko, so link them together if a series/season/movie has trailers.

To-do

• Check if a new provider needs to be made to add Trailers, or if it is possible to re-use an existing provider.

• Modify the series/season/movie provider to add the trailers for that series/season/movie.

I was testing out the beta to see if it resolved some playback issues and found that this plugin was showing as unsupported. If there's any data you want to help figure out why, just let me know.

Error message from logs

Emby.Server.Implementations.Plugins.PluginManager: Failed to load assembly "/config/plugins/Shoko_3.0.1.34/Shokofin.dll". This error occurs when a plugin references an incompatible version of one of the shared libraries. Disabling plugin

Due to ongoing issues with installing plugins in Jellyfin on Windows, sometimes it doesn't want to install.
I am attempting to install Shokofin manually. My question is, the install guide does not seem to be accurate?

It is stated Extract the contained Shokofin.dll and meta.json, place both the files in a folder named Shokofin
However, the latest release has the .dll as ShokoJellyfin.dll not Shokofin.dll. Inside the meta.json as well, it states "name": "ShokoJellyfin",. This makes me question, the proper name of the .dll, as well as the folder name for the plugin.

From the looks of things, you guys are in the process of migrating from ShokoJellyfin to Shokofin, however it does not seem to be done yet.
So I wanted to ensure, as of the time of writing this (Release v1.2.0) the proper format should in fact be which of the following?:

/jellyfin/plugins/ShokoJellyfin/ShokoJellyfin.dll, meta.json
/jellyfin/plugins/ShokoJellyfin/Shokofin.dll, meta.json
/jellyfin/plugins/Shokofin/ShokoJellyfin.dll, meta.json
/jellyfin/plugins/Shokofin/Shokofin.dll

I assume /jellyfin/plugins/ShokoJellyfin/ShokoJellyfin.dll, meta.json to be the proper format?
I ask this because I have tested all of these, and restarted Jellyfin-server between each, and have not seen it appear in plugins. However again, there is a bug on Windows with plugins, and I have had a bit of a buggy experience with manually installing plugins as well. It may need some time to update or fix itself. Unless something is wrong with the plugin, or simply the naming format which is what I wanted to ensure above.
Thanks.

Proposal

I want Jellyfin's "series" to be used to group together Shoko's series (all kinds, e.g. series, web and movies) in something along the lines of Shoko's "groups", where Jellyfin's "sessions" are used to order the items in the group. The "session"'s details will be filled from the series in Shoko, and the "series"'s details will be filled from the the staring point (not necessary the first "session") of the "group". The starting point will be considered the first release in the group (e.g Fate/Stay Night for the fate series)

All misc. (other and parody), trailers and credits will be grouped at "session" index 97, 98 and 99 respectively, specials will be grouped after the episodes from the series they are in, but in a separate "session" ending with " Specials" (or localized equivalent), and the rest of the episodes will be ordered in one of the following ways:

• By chronological order - meaning the first "session" may have been released later then the second "session", and so on. The story is followed from the first prequel to the last sequel.

• By release date - meaning the order of which they were released. Some series expand the backstory of the original by releasing a prequel at a later time. The story may jump a bit, if you watch in this order, but sometimes that may be preferred.

Conflicts

• All Shoko series will be stored under the same "group", so finding a series will be more difficult if you don't know the "group" it belongs to, and individual series will not be searchable.

• Currently undefined behavior when a group of series contain alternate versions with the same prequel/sequel or both. Help needed!

Goal

So if this proposal goes though, we will have three ways to index our library:

• A one-to-one relation between Jellyfin Series and Movies and Shoko Series.

• A one-to-many relation between Jellyfin Series and Shoko Series.

• Whatever TvDB decides. (Because I don't know).

Implementation To-Do

• Add a new API call to get all related sequels and prequels for a series. Either prepossessed, or we can to process it client-side.

  • This will be used to set the session order.

• Modify Shokofin.Providers.SeriesProvider to calculate and generate the structure beforehand (including the session and episode tree) if the "add missing" option is enabled on a library.

• Expand Shokofin.Providers.SessionProvider to create better sessions.

• We need to somehow add an episode, preferably with both relative and absolute numbering according to our order type.

  • Maybe use Shokofin.Providers.EpisodeProvider to optionally recalculate positions on every import if on.

  • Other solutions? Do tell!

• Implement a new SeriesMetadataService and MissingEpisodeProvider, since the default relays heavily on TvDB ids being present, and creates sessions in a TvDB fasion, and there are no way to only implement the later (since it is a one-off class and not an interface), but for Shoko.

Shows

Do the issue persists after creating a library with Shoko set as the only metadata provider? (Now is your time to check if you haven't already.)

• Yes, I hereby confirm that the issue persists after creating a library with Shoko set as the only metadata provider.

Issue

Refresh metadata crashes the plugin like shown in the stack trace.

Description

If groups are not created correctly in Shoko (due to the order of import) and Jellyfin receives the incorrect grouping metadata, Jellyfin will produce an error due to the path changing when recreating groups and then updating series metadata in JF. As a result, the show entry will not display any seasons or episodes until a scan of all libraries is performed manually or by a scheduled task. This is on JF 10.9 with the pre-release 4.0.0.22 version and VFS enabled.

Suggested Solution

Ideally, if possible, it would be helpful for Shokofin to handle the file path changing in the VFS and notify Jellyfin of the change or be able to force a scan of the library. Revam mentioned there might be a way to detect a change using signalr.
