I'm running Jellyfin 10.11.8-36 Package on a Synology DS1522plus DSM 7.3.2-86009 Update 3

I saw the post about the Jellyfin update today, and I know it takes a bit of time for the new Synology Package to show up in the package center however, it reminded me I hadn't checked to see if there were other updates in a while, and there was for ffmpeg 7 so I installed it.

While installing ffmpeg 7, Jellyfin shutdown and now will not RUN. I press RUN in package center and it thinks about it and the run option returns.

I tried restarting the Synology to no effect.

Log shows error : [2026-05-21 21:00:51.498 +09:30] [FTL] [16] Main: Error while starting server
MediaBrowser.Common.FfmpegException: Failed to find valid ffmpeg
at Emby.Server.Implementations.ApplicationHost.RunStartupTasksAsync()
at Jellyfin.Server.Program.StartServer(IServerApplicationPaths appPaths, StartupOptions options, IConfiguration startupConfig)

Everything was done via Package Center, so I have no idea how to rectify it.

Hi all! I'm setting up Jellyfin for the first time after previously running a Plex server (the Plex hardware has since died lmao but it was a great proof of concept). I'm running into the same issue I had with Plex, where Linux has that weird issue about file/folder permissions.

Looking it up, I'm seeing a lot of into about Jellyfin making a user, then having to give that user permissions to the media folder. A Jellyfin user is not being created when I install. I am trying to run Jellyfin under the "docker" user I have created so I'm not running as root.

I am installing with the "add from example" on openmediavault.

It creates a compose file that looks like this (timezone removed for privacy, full filepath removed because idk what info that name gives about my drives lmao)

Trying to add folders to media libraries, I keep getting the "the path could not be found" error. I've tried the options I can find online, but nothing has helped. Any additional help would be incredible.

Hi All

recently moved over from Plex to Jellyfin and really happy with the experience. I tried Cherryfloors cinema plugin but it didn't quite work for my requirements so i built my own.

Trailers4Jellyfin brings a real cinema experience to Jellyfin by automatically downloading trailers for upcoming and recently released movies and playing them before your movies start, no separate Cinema Mode plugin required.

It pulls trailers from TMDB/YouTube based on sources you choose (Now Playing, Upcoming, Popular, Top Rated) and saves them to a folder on your server. When you play a movie, the plugin queues a configurable number of trailers beforehand, optionally matching them to the genre of what you're about to watch e.g. horror trailers before horror films, family trailers before animated movies, and so on.

Trailers rotate automatically: watched trailers are removed and a configurable cap keeps your disk usage in check, so the pool stays fresh without any manual housekeeping.

Trailers4Jellyfin — Installation

Requirements: Jellyfin 10.11+, free TMDB API key

1. Add the plugin repository

Dashboard → Plugins → Repositories → +

https://raw.githubusercontent.com/robadieNZ/Trailers4Jellyfin/main/manifest.json

2. Install the plugin

Dashboard → Plugins → general → find Trailers4Jellyfin → Install → restart Jellyfin

3. Configure

Dashboard → Plugins → Trailers4Jellyfin:

• Paste your TMDB API key
• Set a Download Folder (e.g. /media/trailers)
• Choose your trailer sources and quality
• Save

4. Add the download folder as a Jellyfin library

Dashboard → Libraries → Add Media Library → type: Movies → point to your download folder e.g. /media/trailers → Save → run a library scan

5. Enable Cinema Mode per user

User Settings → Playback → Cinema Mode → On

6. Download trailers

Dashboard → Scheduled Tasks → Download TMDB Trailers → Run

Trailers will play automatically before movies. The task also runs daily to keep your library fresh.

Hope others find this useful.

Hi guys I'm new to self hosting and hosting my own servers and such. However, I've recently managed to get Jellyfin setup and am looking for good looking players on iOS do you guys have any recommendations? I've tried swiftfin but I dont like the UI/feel and it gets my phone really hot.

Basically the title. I'm new to Jellyfin and I'm trying having problems with some audio. Some of my media does not have audio when I am away from home. I'm using tailscale to create a private network so that my devices can connect to the server at home. I'm not really sure how to fix the problem. When I set the maximum bitrate to unlimited, I get audio but the video is borderline unwatchable. When I set the bitrate to auto, there is no audio but the visual is either there or black screen without audio. When I try from computers that are outside my house, it works fine, which is why I believe it has something to do with the compression. Any help would be greatly appreciated. Thanks!

a few months a go i saw a post that show animated TV shows & Movies Covers inside jellyfin , does any one know how to do that? . . . is there a plugin or code?. . . .

Hi all, hoping someone can help. I am after a way that I can include an overlay on my TV shows in Jellyfin that tells me when the next episode of the show airs. Ideally it would be great if it only looked at the next 6 days so it only finds one episode of each show. Hoping there is a plugin that somebody knows of that does something like this for Jellyfin, creating a category on the home page for them would be good also. This is for unreleased episodes, of shows in my collection, not new shows I don't have or the next episode I already have of a show in my collection.

Looking for something like this for Jellyfin

Does anyone happen to know? Thank you.

Someone asked how to make collections and get them to stick. Since OP in that discussion was mod-deleted, I can't reply there, so here's what i tried to post:

As a rule, if several movies have the same first part of their name (e.g. "Star Wars"), JF will create the collection automagically. If it doesn't happen, just go into the dashboard and add a library called "collections," and manually add movies to collections using the vertical three-dot menu on each movie. I've created special collections for Disney movies, Superheroes, the Die Hard series, etc.

I've installed as a temporary solution Jellyfin on my windows PC as a normal application, my library is already on truenas, with file sharing.
In the future I want it to run on truenas but my nas hardware is too weak atm.
I started to create collections, fix covers, descriptions and all of that, but then I was thinking, how painful is to move from windosw samba server to truenas, I noticed that when I identify content, the info file created in the folder of the content has all absolute paths, so I guess it will not work at all later, even if I backup the configs, I'm I right?

I have a pretty big music library in Jellyfin, and one thing I keep missing is a good way to rediscover it. Spotify has Song Radio / Daily Mix, Plex has Sonic Sage, but Jellyfin doesn’t really have an equivalent.

I’ve been experimenting with a plugin that uses audio embeddings to make playlists from a few seed tracks or from listening history. It also keeps per-user “Personal Mix” playlists based on what each person actually plays.

Still early, and I’m testing it on a much larger library now.

Curious if this is something other Jellyfin music users would care about, or if there’s a better way to approach it.

Repo, if anyone wants to poke around: https://github.com/mxschll/jellyfin-harmonie

Hello everyone,

Today I tried moving away from Plex and got Jellyfin running. Wow, there’s so much you can customize.

But now I have a problem: none of the interface changes I made are showing up in the TV apps. After doing some research, it seems like this stuff only works properly in the browser.

So is everyone here mainly using Jellyfin through the browser? Or did I just choose the wrong plugins/themes for customization?

Hi!

I'm newish to Jellyfin and have my server all setup and now sharing with family. I love Seerr and have it setup, but I'd love to see it integrated into Jellyfin. I know I can do this using a browser using many different plugins, but I want to have it using my apps and need to know which apps integrate seerr, or the older jellyseerr.

Right now, the only one I've found is Wholphin which has a great integration and allows users to request new movies.

Are there any other Android or Android TV clients that do this?

I'm also very interested in finding out whether any iOS clients do this... several family members are on iPhones and Apple TV.

Thank you!
