Client MPV Shim v3: Library Browser, Offline Sync, and Jellyfin v12 Support

Thumbnail

102 Upvotes

UPDATE 2026-10-04: v3.1.0 was released, go grab it here!

MPV Shim v3 reinvents the client. There's now a full library browser inside MPV, supporting all Jellyfin media types including videos, books, audiobooks, comics, photos, and music. Offline Sync, Live TV, and fast user/server switching are also added. This is also the first MPV Shim version to support Jellyfin v12 without legacy auth turned on.

This is all done without any webviews or heavy copies of Chromium. Nothing touches MPV's video output either, MPV Shim draws into MPV so gpu-next works perfectly. We don't redirect it or recomposite it. HDR, Dolby Vision, and custom shaders all work.

MPV Shim retains the ability to use MPV's default player controls and has improved support for custom OSCs and player keybinds. You can also configure the player to start minimized and stay out of the way, like the past versions did, or you can use the new 10ft browser UI with gamepads, cast controls, and keyboard navigation from your couch. There's also optional presets for audio passthrough, improved shaders with per-library support, and volume normalization (night mode).

Thanks to everyone who helped test the pre-releases, I couldn't have done it without you!

Discussion If you vibe code a client, make it wild

75 Upvotes

I’ve been coming across so many jellyfin clients that it’s getting tiring, as all of you are. The basis is always the same : MPV, libVLC, ExoPlayer, so why bother if the result is the same?
Which is why on the other hand I’ve been so intrigued by vibe-coded clients for legacy platforms that get no love and might genuinely get some “cause I can” client that might really be cool. After all, installing into an old device (especially a gaming console) a homebrew jellyfin app might get you back into the games of your childhood.
So I thought: If you want to do it - go all the way, port it to the ps1, the vita, invent a way ti make it work on the gamecube, on solaris os, on powerpc mac os, but make it worthwhile.
We could even compile a list of “jellyfin clients for obscure and legacy devices”, would be cool.

Question What media do you have in your server that isn’t the typical stuff like music, movies, and shows?

23 Upvotes

I was thinking about adding some random YouTube videos I enjoy a lot but I’m not sure. Also I don’t know if there are other options than what I listed and want to know the possibilities that are available to me to take advantage of.

So what do you have in your server?

Help Request Jellyfin arranging episodes out of order

3 Upvotes

I'm trying to organize an anime show -- the directory is full of subdirectories titled like Season 01, Season 02, Season 03, and the files are named exactly like S01E01.mkv, S01E02.mkv, S02E01.mkv etc -- with no other junk in the filenames. TMDB was being dumb about recognizing the show and episodes so I prefer my own custom numbering. Everything is named correctly and organized correctly.

I've tried deleting metadata multiple times but pulling up some seasons will show the episodes out of order, eg Season 3 lists its episodes in the order

  • s03e05, s03e06, s03e07,
  • s03e01, s03e02,
  • s03e04, s03e03,
  • s03e10, s03e11, s03e09 ...

which is completely wrong and makes zero sense.

No clue how to fix this. I just want Jellyfin to treat the subdirectories titled as "Season 01" as seasons of the show and list the episodes in filename order, eg s01e01 is the first episode of season 1, s01e02 is the second episode of season 1, etc. Any help would be greatly appreciated!

Help Request Jellyfin totally stopped working on Ubuntu Server/Proxmox. "Insufficient Free Space"

• Upvotes

I have a full media server setup using Jellyfin as the media player and only jellyfin has fully stopped working. The other services I have running in a seperate docker are running perfectly fine, however Jellyfin has totally shut me out. This is the last thing the log says. Written clearly is "Insufficient Free Space", but I do not know how to clear this manually in the Ubuntu Server console and whether or not it will fix anything. I think I caused the crash by trying to add a maintenance task while being out of cache space. If clearing the cache manually fixes this issue I would also take advice on how to keep it from filling back up please! My experience is extremely limited as I haven't touched the console since setting it up unless it needed to be restarted for whatever reason. any help would be greatly appreciated!

Solved How to get from 10.10.6 to 12.1? (Windows Server Binary)

9 Upvotes

The upgrade post for 12.0 says you need 10.10.7 -- which is not available anymore on the Jellyfin site, and there's no package for it in the GitHub repo that I can find.

I looked for the upgrade path for 10.11, and once again it says you need 10.10.7 before upgrading.

So what am I supposed to do here?

Help Request New to Jellyfin. Web browser extremely slow, apps say "server unavailable"

0 Upvotes

Hi all,

So last night after years of frustration with Plex I decided to try Jellyfin, so I installed it on my Synology DS423+ NAS, set the library up and it worked without issue. This morning however, if I try to access it via any app, either I get "server unavailable", or it spends forever trying to load without getting anywhere. If I try to open up Jellyfin via my browser, it takes several minutes to even open the web page, and when it opens every library action is extremely laggy and the libraries whilst present, will mostly not load at all (spinning blue wheel for infinity). Sometimes it won't even open at all and I get a "server unavailable" error, even though my NAS is online the whole time. Any help?

(Please note that I am a bit of a networking noob, so please have patience!)

Question Remote Access From The Roku App

2 Upvotes

Hello, to be brief, i have my instance of jellyfin running on a machine in my house.I have it setup with cloudflare tunnel and zerotrust. I want to give my girlfriend access to my jellyfin on her tv, but when i put in my jellyfin url (i have a domain), it doesn’t get picked up. it works fine on her PC and on my phone.

I read that zerotrust doesn’t work with jellyfin roku app, and i read around that the best way to give other people access is to set up tailscale on their wifi system or whatever. i’d rather not, to keep things simple for my user. any one have any ideas or advice they could give me for this situation?

Question Second HD - raid or extra

4 Upvotes

I set up my Jellyfin NAS just as hard drives sold out, so until now I’ve been using only a single drive (4TB). I recently was able to get a second one at a reasonable-ish price but when I put it in the NAS I accidentally configured it for a raid array. I’ve already copied all my movies and shows to the drive, and it’s at about 3.5T usage.

Should I backup&delete the storage volume and start over with two drives worth of storage or is the redundancy from the raid better even though I only have one drive worth of storage space (until I can get a third, that is)?

Question How to remove these arrows and use an auto single page?

Thumbnail
gallery
3 Upvotes

I'm currently using Mihon with local files to read manga on my smartphone, but I'd like to switch to Jellyfin since I already use it for pretty much everything else.

This is my first time setting up a book/manga library on Jellyfin, and I wasn't really impressed with the built-in reader. It seems to be missing a bunch of basic features, unless I'm just missing some settings.

Is there any way to customize the reader, specifically to remove those arrow indicators and have it automatically fit a single page to the screen? Right now, it seems to load the entire page and I have to zoom in, or switch to double-page mode and then back to single-page mode.

Coming from Mihon, the reading experience feels pretty clunky. Is there a setting I'm missing, or is this just how the native Android app's reader works?

Help Request Missing metadata

Post image
0 Upvotes

I've been having an issue with a few new anime episodes where they don't load up any of the episode info and just leave it blank like this. I've manually entered into the info, but I'm wondering how do I make it so that the episodes will pull data from TVDB correctly right away?

I have the TVDB plugin and it seems to work 99.5% of the time, but then once in a blue moon something slips past like this. Just wondering if anyone has a fix or if it's just a quirk of the TVDB metadata extractor.

(Files are uploaded and named correctly, so I don't think that's the issue. I've also done a library scan for missing metadata 4 times in the last few days)

I made the switch to jellyfin today. Spent 4 hours installing on my HTPC and seemed to go well. I added to plugins and restarted the desktop app. Now it won't accept my log in info. Says either id or password is incorrect. Used the same credentials all morning without problems. I tried forgot password, the .json file never shows up with the code. Any ideas on my options are? It's a windows 11 pro computer.

Bug Backdrops Not Showing Up on Website

This started happening out of nowhere. Backdrops are not showing up. I don't have any extra plugins installed, and I didn't change anything. They just stopped appearing. I'm using Jellyfin 12.1.

For some reason, they do appear on my phone, but only on the mobile site. If I switch to the desktop version, they don't show up.

I also tried different browsers, but nothing worked. I also restarted the container.

Client Best jellyfin clients

108 Upvotes

Been on Jellyfin for years. Here are the best clients per platform:

iOS / Apple
1. Zuno – best I've used, but limited without a sub
2. Swiftfin – clean and simple, no bloat
3. Moonfin – solid, free, downloads with external subs
4. Jellyfin (official) – really good, but won't grab external subs on some downloads

Android
1. Moonfin – solid, free, downloads with external subs
2. Jellyfin (official) – runs great, still no external sub downloads

LG webos
1. Litefin – amazing and lightweight, but needs Homebrew to install
2. Jellyfin (official) – runs like crap even on high-end LGs. webOS is just trash

Android TV / Google TV
1. Wholphin – best on Android TV, not even close
2. Moonfin – does the job
3. Jellyfin (official) – basic and ugly

Help Request Can’t Login on a Samsung TV

3 Upvotes

I downloaded the official Jellyfin app onto my in laws TV for their Samsung TV. It downloaded just fine but when I tried to log into my server it keeps saying username or password is invalid. But when I login on my phone on the same WiFi it works just fine. I can’t even use Quick Connect because it says it’s not active on this server even though it certainly is. I even re-added the server and tried logging into like 4 times.

I deleted the user and re-added as well just to make sure I tried everything. Any suggestions?

Edit: Server name on the TV matches the server name on my phone

Edit 2: There is no activity being logged to show any attempts at login from the TV device. I only see attempts from my phone app or phone browser

Help Request Fladder crashing server?

2 Upvotes

I've got jellyfin running on Ubuntu server. I just installed it yesterday from the script they provide so I'm assuming it's the newest version. I was testing out some different clients on shield tv. Wholphin works fine and so does the official app on my phone. I downloaded fladder on my shield tv and logged in and as soon as I try to watch media it says it can't find it and then says the server is offline. If I try to get to the server from a browser it looks like it's down. If I wait a while it will come back up and I can use other clients. If I try to open fladder again the same thing happens. Has anyone else experienced this?

Question Help with my HTPC setup

0 Upvotes

A while back I built a bazite box (Lenovo m70q) for my living room to stream games and replace my fire stick as my jellyfin streaming device for my living room tv. I have the jellyfin desktop client in TV mode but the scaling for the font is super small and it just feels less responsive than when I was using the fire stick and I can't edit things like I used to on the firestick. Things like changing the size of posters when looking at my library or accessing the sidebar. Looking for suggestions on a different jellyfin client to use or settings others have found helpful to make my jellyfin streaming more responsive and easier to navigate and customize.

Question Moving to JellyFin (maybe) but have a few questions

0 Upvotes

Hopefully I can get a few questions answered here. Thinking of moving from Emby to Jellyfin, now I know its not going to import databases, etc. And I am going to more or less have to rebuild the images and what not from scratch (it will read form .nfo files from what I can tell)

But the main question I have is in regards to clients. I understand that a lot of people recommend Wholphin and there's a bunch out there. I wouldn't mind paying for one. But the MAIN question I have regarding client apps is

Are there any apps out there with full plugin support from the server side of things?

Most specifically Home Screen Sections

I like Emby and it seems Jellyfin will give me all that Emby offers (as it was a fork from way back) but the thing I don't like about most of these home theatre options is a real lack of a true Netflix style home screen. I have a solid collection of movies and TV shows, and it can be a hassle to remember what I have and having several genre rows and "because you watched.." rows really scratches that itch.

So, are there any client apps that respect the creation of new rows? I can't seem to find answers on any official channels...

Thanks

Help Request Jellyfin with a Raspberry Pi as a client

2 Upvotes

So I'm using a Raspberry Pi 5b as a Jellyfin client next to my TV. I installed the last Raspberry Pi OS on it and I'm using Chromium to connect to my server.

I was using a quite old version of Jellyfin on my server and everything was fine. But I decided to update to the last version (12.0.0) and now H265 movies pause every 3 second and sometimes don't play at all.

I read that Jellyfin support for Raspberry Pi isn't as good as before but I'm not sure if it's on the server side or the client side. Is there anything I can do to make it work with my Raspberry Pi or do I need to change my client?

On other clients, I don't have any problem.

I really don't know a lot about Jellyfin configuration so maybe the solution is really obvious.

Thank you.
