Kodi and Jellyfin local assets - Frage - 2025-09-06

Hi,

I have a Jellyfin server running on Docker with the latest build available at the time of writing this post.

Until yesterday, I was using Jellyfin on my desktop, phone, and the web app for movie playback. I recently upgraded my setup and bought an AM6B Plus running CoreELEC for Dolby Vision playback.

To use it, I installed the Jellyfin add-on on the AM6B Plus (in Add-on mode), and also the Jellyfin Kodi plugin on the server side, and now I can access my Jellyfin library.

The issue I have, and I couldn’t find a solution or another thread mentioning it, is related to movie assets from Jellyfin.

On my NAS, every movie is stored in its own folder. Each folder contains the following locally downloaded assets:
  • backdrop.jpg
  • cover.jpg
  • logo.png
  • thumb.jpg
I don’t want to use external assets, only local ones.

From my other Jellyfin apps everything works fine, all movies display their correct poster (cover), background, logo, etc.

But on the AM6B Plus, some covers appear as blank. Backgrounds and logos display correctly, but a few posters are randomly missing, and I can’t figure out why.

For testing, I tried removing a cover.jpg from a movie folder and rescanned the metadata. Jellyfin then fetched a new poster from TMDB (which I might missed something because I don't want that), and after refreshing on the AM6B Plus, the new TMDB cover was displayed correctly. But if I put my original cover.jpg back and refresh, the AM6B Plus shows a blank poster again.

Did anyone experienced that behavior / know how to debug ?

Problem solved. The covers were in webp, even tho they have jpg extension. Corrected after conversion. Kodi seems to don't be compatible with this format compare to Jellyfin.

Now my last issue with Jellyfin server / Kodi client is about trailers. Trailer are always from Youtube, Kodi doesn't read the Jellyfin local trailer.

Also for some reason the nfo generated has this info for example :
Code:
  <trailer>plugin://plugin.video.youtube/play/?video_id=bQlwYnouC98</trailer>
  <trailer>plugin://plugin.video.youtube/play/?video_id=qx12pLUUDZs</trailer>
  <trailer>plugin://plugin.video.youtube/play/?video_id=H68iU7fqW-w</trailer>
  <trailer>plugin://plugin.video.youtube/play/?video_id=QHhn7hKHCKg</trailer>
  <trailer>plugin://plugin.video.youtube/play/?video_id=aynl3G87F80</trailer>
  <trailer>plugin://plugin.video.youtube/play/?video_id=A8CMggxPlcc</trailer>
  <trailer>plugin://plugin.video.youtube/play/?video_id=u3Pc92BFbOg</trailer>
  <trailer>plugin://plugin.video.youtube/play/?video_id=NN5H68wIsak</trailer>
  <trailer>plugin://plugin.video.youtube/play/?video_id=5ulVRDlX6gU</trailer>
  <trailer>plugin://plugin.video.youtube/play/?video_id=D2veWoCsnWk</trailer>
  <trailer>plugin://plugin.video.youtube/play/?video_id=gloeLXVV_-M</trailer>
  <trailer>plugin://plugin.video.youtube/play/?video_id=jFBeY-xr30Y</trailer>
  <trailer>plugin://plugin.video.youtube/play/?video_id=_SF-WV96iVk</trailer>
  <trailer>plugin://plugin.video.youtube/play/?video_id=hMQp7m00Lmk</trailer>
  <trailer>plugin://plugin.video.youtube/play/?video_id=RZQnvb0WDuk</trailer>
etc

And a minor bug, when playing a trailer from the Jellyfin app this time, the top left title is wrong.

For example I select my Movie Asterix & Obelix Mission Cleopatra (2002), trailers play, locally I have a Asterix & Obelix Mission Cleopatra (2002) Trailer.mkv, on the player I can read "Bucky's '70s Triple XXX Movie House Trailers Vol. 18".
