KOFin: Jellyfin on e-readers - Topomov - 2025-02-15

Hey everyone,

I’d like to share KOFin, a KOReader plugin that integrates with Jellyfin, making it easier to sync your book library and reading progress across devices.

Being a KOReader plugin, it should work on many e-readers although I've only tested it on an old jailbroken Kindle.

PS: It's something I've hacked together without knowing much of KOReader's codebase or Lua. Feel free to contribute with MR or suggestions. Particularly, I've had issues properly aligning Jellyfin's CFI location and KOReader's XPointer.

Wow, awesome timing as im trying to setup something like this for my wife. Do I need to have the OPDS plug in enabled as well? Or just having a book library is enough?

Hope it works well for you!

Also, there is no need for OPDS

I love the idea of this, tried it on my kobo but it crashed when I entered the server url. The error said something along the lines of it expecting an integer in that field.

I suspect your issue is with the Port field.

Can you give me an example of the input you used?

To give you examples of what the app expects. Any of those should work:

url: 192.168.1.10
port: 8090

url: myjellyfin.mydomain.com
port: 443

Tried jellyfin.myserver.com and port 443, got a crash when I enterned my credentials

My bad, I had hardcoded the protocole because I did not anticipate to share it with others.

You should download the new version I just pushed and then try something like:

Code:
url: http(s)://jellyfin.yourserver.com
port: 443

Btw, while testing and for my personal usage, I used my internal IP for connection as the url and that worked great. For some reason, when using a reverse proxy, requests to the server still work but take drastically longer. Can you tell if you encounter the same issue or if it's something with my own setup. Thanks!

Hi, I just downloaded koreader and tried the steps above with my reverse proxy in the URL and port as 443. It is still crashing.


RE: KOFin: Jellyfin on e-readers - johsmith - 2025-04-07

Update: When I manually add https:// in the IP field it no longer crashes. But I am still having trouble connecting through reverse proxy

Seeing this now
