Jelyfin is awesome but in my case plugins for metadata scraping are behaving somehow weird and slow. And I don’t trust Jelyfin regarding write operations so access is just read-only.
I use tmm v3 for metadata scraping and renaming, which work great in my case.
Last time when I checked, I have to pay for needed plugins on v4. V3 is a bit limited but “free” and fine for me.
I plan to write my own cli tool just for scraping metadata, subtitles, nfo generation, renaming,… maybe some day…
