That’s good to know, appreciate that. It SHOULD still be working. It has the ability to read the subtitle tracks off any supported media. I will say, I am not as thorough in my manual testing of Jellyfin as I am for Plex.

Any chance I could bother you to open a GitHub issue? Or just give me some details here? I will definitely get this fixed and make sure there is a test case for whatever this specific scenario is.

Here’s what would be super helpful for me:

1. In Jellyfin, open the “Media Info” and scroll down to the Subtitle section. What codec and language is it showing? You can paste the full info if you want. There may be more than one track.

2. In Cliparr, while those subtitles are visible and playing in Jellyfin, look in the right-side Subtitles sidebar. See where it says “+ Add subtitle”? To the right of that is a (…) menu. Click that (…), what does it say in there?

I assume for you, it might say “Start Blank”, which would mean it did not recognize any subtitle tracks, either from the file, or as a “sidecar” stream.

I’m going to get a PR open to add more logging around subtitles specifically. I checked and unfortunately I do not have the log in place that would be the most helpful here. But please do tell me if you see any browser console logs. If you do open an issue, I’ll send you 3.1.1-rc soon.

Be careful to check any logs for private info before sharing. Anything you might not want to share, like maybe user folder names, etc.
