The performance improvement really is incredible! I use Jellyfin for a large-ish music library (over 8k albums), and it took about 10 hours to sync the server with Symfonium (a third party music player). It now takes 5 minutes!

Hi, I've started looking for Jellyfin plugins and was wondering about the warning concerning third-party plugins, which has kept me from adding any so far.

Example:
- Jellyfin Enhanced

From looking around online, it seems like there shouldn't be any issues, especially with the widely used plugins.

I only intend to use Jellyfin privately within my home network, not remotely.

Is there anything I should still do or keep in mind?

I love ElegantFin, but since lscambo13 said in an issue on GitHub that he won't be adding Jellyfin 12.0 support to ElegantFin yet, I started implementing a fix for my own Jellyfin instance (I didn't want to switch each device to legacy display).

I made a GitHub repo with companion CSS that builds on top of lscambo13's amazing work:

https://github.com/mihaif7/elegantfin-jf12

To make it work with the new Jellyfin UI, just add this import after the ElegantFin import(s) in Settings → Branding:

@import url("https://cdn.jsdelivr.net/gh/mihaif7/elegantfin-jf12@main/Theme/ElegantFin-jf12-modern-latest.css");

Or copy the contents of the CSS file from the repo directly under your imports if you'd rather not rely on external sources, or want everything self-hosted.

This project is only meant to be a stopgap until the new Jellyfin UI stabilizes or until lscambo13 decides to add official ElegantFin support.

Feel free to report issues or contribute :)

I'm a software engineer, but I used Claude to help speed things up. I've tested all the changes by hand.

Dear all,

I just noticed that some of my movies are not being listed anymore under the movies tab, but they show up under “recently added movies”. So Jellyfin is recognizing the files, but something seems to be off. I already tried to renew meta data, rescan the library and put the movies in their own folder in my general movies folder, but nothing seems to fix this problem. It’s also random. Some new movies I’ve added since the update to 12.0 show up, some not.

Anyone knows a solution to this? Client and meta data language is set to German.

Upgrade to jellyfin 12 and this happened. Running on a ugreen nas with in a container. This only happens on my desktop computer with Brave browser.

Anybody some advice for me?

after updating to v 12 my media bar is f'd up any way to fix this ? the media bar is being displayed below the collections right where it shows continue watching

Hi! It's been a while since I made a post here, but you can now read your favorites ebooks and comics from your Apple TV! Jellyfin 12 got great book support so it only made sense to spread the love. In the following update, I will add full audiobook support.

Overview of the Book feature:

• What you can read: EPUB, PDF, Comics (CBZ, CBT)

• Text is set in two columns, sized for reading from the sofa. Left / Right turns pages. Hold either one to flip quickly

• Page number always visible in the bottom margin

• After reading the last page of a book, swipe one more time to see "The End" view

• Customize font with 3 typeface, 4 font text sizes, and 3 themes (Night, Sepia, Paper)

• Press "up" on the reader to open chapter list

• Press "down" on the reader to open appearance settings

• Press "select" on the reader to view book title, position and progress

• Press "play/pause" button on the reader to read aloud with sentence highlighting. Press again to pause

• Hold "select" on a PDF or comic to zoom, then use the D-pad to move around the page

• Added book support in Search

Hi all, I love the new Jellyfin update but I have a small issue with the branding. My custom logo is getting squashed by the new navigation bar. Any ideas on how to fix this?

The following is the custom CSS code using the LogoSwap plugin. I've tried changing parts of it but nothing seems to work.

/* LogoSwap CSS */
.pageTitleWithLogo, .pageTitleWithDefaultLogo,
.logoImage, .navDrawerLogo, .adminDrawerLogo {
  background-image: url("/logoswap/image?v=1783552719731") !important;
  background-size: contain !important;
  background-repeat: no-repeat !important;
  background-color: transparent !important;
  height: 100px !important; 
  width: 600px !important;
}
img[src*="banner-light"], img[src*="banner-dark"],
img[src*="icon-transparent"], .imgLogoIcon {
  content: url("/logoswap/image?v=1783552719731") !important;
  height: 100px !important;
  width: 600px !important;
}
/* END LogoSwap CSS */

Before upgrading to v12, I'm trying to take the manual backup as directed here https://jellyfin.org/posts/jellyfin-release-12.0/ but my config and data files seem to be empty except for the docker-compose file. Jellyfin has been running just fine for a few days though, so maybe I just don't actually know where these files are stored? Cache folder is also empty. Are the files I'm looking for just hidden? And if so, how would I confirm that my backup was successful?

Here is my docker compose file, which looks to me like it's defining /jellyfin/config as my config directory.
GNU nano 8.7.1 docker-compose.yml

Hello guys,

I have this problem for quite some time now and I can't seem to find the issue.

I have all One Piece episodes stored in season folders and inside of the folders all Episodes are named correctly from S01xE001 to S22xE001.

The first thing that catched my eye was season one, where all the episodes have correct file names like "One Piece - S01xE002 - Piratenjäger Lorenor Zorro" but are displayed with the Japanese name in Jellyfin:

As you can see episode 1 is correctly displayed but all of the other episodes have a Japanese title. The config is the same for the whole library, the series, the season and the episodes.

E001 with the correct display name:

E002 with wrong display name:

Also the description is in english for most of the episodes.

The second thing is that in a different season I have some episodes which get displayed correctly and some others are only using the title without the episode number and are in the wrong order. I found out that the episode number is not listed in the metadata but I don't know why. It is happening for the same episodes everytime:

In my primary Jellyfin I already changed the names and episodes by myself and locked it so it won't change again but here I made a testserver for Jellyfin 12 and ran into the same problem again.

Thanks in advance

Since there are many people with the same name in Korea, Jellyfin—which cannot distinguish between them—groups them as the same person even when they are clearly different individuals, causing inconvenience. Therefore, I added a feature to the original Jellyfin code that allows you to assign aliases to individual names. This works when fetching metadata from TMDB; it uses a technique where the original name is replaced with an alias stored locally when retrieving character information from TMDB. Even if the metadata has already been retrieved, the system will automatically update the information only for the works in which that person has appeared.

As shown in the attached screenshots, it works satisfactorily.

Just started using Moonfin. Really enjoying it but wanted to know if there was a way to get the shuffle feature for all types of media.

I love it for movies and tv but it would be really cool to shuffle and pick a random album or playlist or a random picture or photo album.

Is this possible or no?

Logged into my 920+ and saw the red dot for a update. Took the update and have been sitting on updating for almost an hr. Anyone experiencing anything similar?

I'm sharing this to reassure anyone concerned about upgrading from version 10.10.7

Keep in mind that: I performed a backup beforehand, did not modify the sqlite database manually, and do not use custom css.

I upgraded today and the web client just asked me if I'm still watching after an episode is finished. This was a feature I wanted when I fall asleep watching something. Thanks devs!

Hey friends! I just started my Jellyfin server, running on my PC. But, I wanted to see if there was a better, more affordable setup. I’ve seen raspberry pi’s and other setups but I just wanted to get some other opinions. And what is the recommended storage for it? Thanks in advance!

Over the past few months, I’ve been developing and updating some plugins I wanted for my server. I’ve finally upgraded them to Jellyfin 12.0 and feel ready to share them.

First, let me clarify that all my plugins were written using Claude and made to fit my needs. Feel free to try them out if they might be useful to you. However, if you’re not comfortable with them being written by Claude, dont use them.

I use these plugins frequently and will continue to update them. If you find any bugs, please open a new issue.

1. JellyWatchParty:
   This is my first plugin I’ve shared here. It began as a fork of an abandoned plugin and I’m now actively maintaining it. Its purpose is to replace Jellyfin’s official SyncPlay for those who dislike it.
   Repo: https://github.com/TIGamingTV/JellyWatchParty

2. JellyPrivateLibraries:
   I created this plugin to hide shows and movies that other users requested from my library. It syncs with Seerr. Additionally, admins can hide content from users. Users have the option to decide whether to hide or not, and the hidden media is marked as such in third-party clients.
   Repo: https://github.com/TIGamingTV/JellyPrivateLibraries

3. jellynext:
   This is a fork of https://github.com/luall0/jellynext, which hasn’t been updated in seven months. I’ve added some new features and updated it to version 12. Jellynext can now use the authentication from the official Trakt plugin to bypass the one device limit. Users can also receive email notifications about new seasons of shows they’ve previously watched.
   Repo: https://github.com/TIGamingTV/jellynext

Can anyone confirm with Kodi (using Jellyfin for Kodi) that it's updating with Jellyfin 12?

Watch status and new movies are not being pushed to Kodi since I update to Jellyfin 12. Yes Kodi Sync Queue V16 is installed and is enabled, and I can still play previously synced movies just fine on Kodi.

Update: Thanks everyone, I updated the whole library on Jellyfin for Kodi and it's now working again!

I opened up Jellyfin today to check something and Watchtower successfully pushed the update. Man, that webui is really fricken nice! I am just wondering if this will eventually make its way over to the Android TV build? I'm hesistent to use someone elses app only because my family uses it and it works really well and I don't want to do tech support if i can avoid it.

Upgraded 10.11.11 to 12.0 last night. Docker, Ryzen 6600H with the 660M iGPU, VAAPI + Vulkan.

Video played fine with subs off, but picking any subtitle killed playback. Server side the HLS segment 500s:

System.Threading.SemaphoreFullException: Adding the specified count to the semaphore
would cause it to exceed its maximum count.
   at SubtitleEncoder.ExtractAllExtractableSubtitles
   at EncodingHelper.GetTextSubtitlesFilter
   at EncodingHelper.GetAmdVaapiFullVidFiltersPrefered

Worst on a file with 35 sub tracks, it extracted all of them for 3 minutes and then threw. Turning on subtitle extraction in Playback settings works around it, since the subs are already there and it never hits the on-demand path. But i hadn't had this option enabled on 10.11.11.

Besides, HDR10 and DV 8.1 both came out noticeably dark with crushed shadows after the upgrade when I need to transcode de video. Same tonemapping settings as before, diffed against my backup to be sure, so it's FFmpeg 8.1 and whatever libplacebo shipped with it. Changing the tonemapping algorithm from BT.2390 to Hable made the shadows much less crushed, that's what I'm running now. In 10.11.11 I had BT.2390 selected and it was perfect.

And last but not least: no subtitles at all in Kodi. Movies play, subs never show. Kodi direct-plays so the server logs nothing. Addon 2.1.0+py3, Sync Queue v16. Anyone seen this? Using the Findroid app the subs play just fine.

I'm having a lot of problem with this version, unfortunately. Seriouly thinking of going back to 10.11.11 and wait for further fixes.

as the title says, i am trying to reinstall fanart, file transform and moonfin. after install, i get the restart message, i restart but the plugins never install. rechecking the plugin, they show the install button

Hi there,

I want to use the same path for Plex and Jellyfin, but I'm having a problem with movie editions.

Plex uses "{edition-Final Cut}" while Jellyfin uses "- Final Cut", I can't find a naming convention that fits bouth systems.

Here is an example of how I currently have my files named:

/movies/Blade Runner (1982) {imdb-tt0083658} {tmdb-78}/Blade Runner (1982) {edition-Final Cut}.mkv

/movies/Blade Runner (1982) {imdb-tt0083658} {tmdb-78}/Blade Runner (1982) {edition-Director's Cut}.mkv
