This issue respects the following points:

  • This is a bug, not a question or a configuration issue; Please visit our forum or chat rooms first to troubleshoot with volunteers, before creating a report. The links can be found here.
  • This issue is not already reported on GitHub (I've searched it).
  • I'm using an up to date version of Jellyfin Server stable, unstable or master; We generally do not support previous older versions. If possible, please update to the latest version before opening an issue.
  • I agree to follow Jellyfin's Code of Conduct.
  • This report addresses only a single issue; If you encounter multiple issues, kindly create separate reports for each one.

Description of the bug

Two libraries (a Shows and a Movies) are configured to watch their respective directory trees, and to write thumbnail images and NFO information to disk. This seems to work fine in that, when new video files are created, associated metadata and images appear to be available as they should be through normal browsing, the videos are shown in recently added lists, etc. On disk, the thumbnail files are created as expected - but NFO files are not created. If I use the admin Dashboard > Libraries > (whatever) > Scan library > Scan for missing metadata action, the missing NFO files are created successfully.

Scanning for new and updated files does not create the files. The Scan Media Library task is enabled (and running) and does not create the files.

Notable library settings:

  • Enabled real time monitoring
  • Disabled all metadata downloaders of any kind
  • Never automatically refreshes metadata from the internet
  • Enabled NFO metadata saver
  • Enabled embedded image extractor and screen grabber (disabled all others)
  • Enabled saving artwork into folders

I think this also affects new shows and new seasons, but I don't remember that for sure...

I'm willing and able to review the source, if that helps, just point me in the right direction of where to start looking. I would speculate that NFO saving for watched files works in general (otherwise surely someone would have noticed a problem by now) but is set up such that it only happens when using external metadata and/or when refreshing from the internet.

Reproduction steps

Setup:

  1. Create a Shows library with the above settings
  2. Create a show and season, add episode videos, add artwork, do whatever else you want
  3. Run a "missing metadata" scan and ensure all NFO files have been created

Reproduce:

  1. Add a new episode video

What is the current bug behavior?

  • The thumbnail image is created automatically within a couple minutes of the new file being added
  • The NFO file is not created at that same time
  • Even days later, the NFO file still has not been created automatically

What is the expected correct behavior?

  • Both the thumbnail and NFO file are created automatically, presumably at the same time

20:04 was me logging in to rescan metadata. For those logs, the same ffprobe

there's nothing else (even for the two new ones).

I have the problem of incomplete NFO when I add multiple movies, the ffprobe result with audio track and other data is not added to the NFO. This is a random problem (like a thread concurrency problem that I can't explain). Also the "scanning for missing metadata" don't work for entire library, I must click on each movie "search for missing metadata" one by one:( to get the good NFO.

I have to say that the new Jellyfin version's ability to recognize nfo files is practically nonexistent. Why do I say this? I've generated nfo files using tmm
Image

Looking at this image again, the video is already S01E01, but what does it show? It doesn't display the season and episode numbers, and it will display Unknown Season

In this case, I really want to revert to an older normal version very very bad. I no longer want to update Jellyfin anymore

I just now went to the current 10.10.6 and no change: new video files are picked up, thumbnails are created, but .nfo files are not created.

I'm still able to help out on the code side of things if someone can point out where I should start looking... From tanmoumou252's comment I'm wondering if there are larger problems with NFO files and watched directories?

In my experience, the nfo files created by tmm stopped working after an update to a specific version of Jellyfin. The server appears to read nfo files only once, and subsequently, any new videos and nfo files added to the folder are not recognized by the system, all showing up as unknown seasons.

The solution is straightforward: simply rename the folder, refresh the media library, and the nfo file should be readable again. Alternatively, you can revert to an older version, likely from early 2023 or 2024, when this problem didn't exist
