I'm getting some confusing behaviour with episode thumbnail generation in jellyfin. This is happening with all my episodes so I'm picking a show and season at random to showcase here.
Episodes up to a certain number (this varies by season/show but around 5 or 6) will have the correct thumbnail, but then episodes after that will all have the same one of some episode in that series.
Each episode has a thumbnail file associated with it that's mapped to it in the nfo. For example:
Make Some Noise (2022) - S01E01 - HBOs A Game of Rock Paper Scissors [WEBDL-1080p][AAC 2.0][x264]-BTN.mkv
Make Some Noise (2022) - S01E01 - HBOs A Game of Rock Paper Scissors [WEBDL-1080p][AAC 2.0][x264]-BTN-thumb.jpg
In the nfo: <thumb>https://artworks.thetvdb.com/banners/v4/episode/9214443/screencap/62a84ce45dd5e.jpg</thumb>
which goes to the correct thumbnail that matches the content of the downloaded jpg.
This is the case for episodes that display the correct thumbnail and for episodes that display a different one.
If I refresh and replace all metadata including existing images it will not change things if I don't take any other action.
If I manually select a particular episode and "edit images", search for a replacement image and download that one (which will be correct) redoing the refresh and replace all metadata including images
will change which episode thumbnail the incorrect shows are receiving (including the one I just manually selected) but otherwise won't change the result, a few early episodes in the season will have
correct thumbnails, the others will all share one episode's thumbnail from that season.
I'm running jellyfin 10.10.1 in a docker container using the linuxserver image. The thumbnail presentation issue is present in web, mobile (iOS) and AndroidTV clients
I've got the tvdb metadata plugin installed. For metadata readers I have NFOReader at the top, YouTubeMetadata is also listed but shouldn't be used since they have NFO files
I don't have any metadata downloaders set and for image fetchers I recently turned on the tvdb downloader to test replacing images
I have "save artwork in media folders" checked so it should be expecting to read images from the location I mentioned above
The metadata is originally generated by sonarr if that's relevant
Watching the logs when I do a refresh I see some messages about processing subtitle files but nothing about images
This was working before, although I honestly didn't notice exactly when it stopped, it might correspond with a jellyfin upgrade but I can't be totally sure
Any suggestions for further troubleshooting or solutions would be appreciated
