Music library scraping not working: can't get any metadata from FLAC files - ricobelo - 2025-09-24
Hello,
I'm new Jellyfin user, and I experiencing a weird issue while trying to add my music library.
I'm running Jellyfin 10.10.7 on Debian 13/Trixie VM, and my media libraries are mounted thrught NFS exports on Jellyfin server
I added a fersh music library that way:
I only tuned the localization in French, keeping everything else as defaults. But as you can see I get absolutely no metadata
In Jellyfin logs, I only see few lines :
Code:

Of course, files are accessibles from jellyfin system user, and FLAC files contains correct metadata. Besides ffmpeg command successfully executes from shell :
Code:
jellyfin:~# sudo -u jellyfin /usr/lib/jellyfin-ffmpeg/ffprobe -analyzeduration 200M -probesize 1G -i file:"/mnt/music/flac/AC-DC/1986_Who_Made_Who/05_ride_on.flac" -threads 0 -v warning -print_format json -show_streams -show_format

}The video library scraping completed without any issues...
Any idea of what's going wrong and how to fix it ?
Thanks,
