Subtitles added to mkv won't show up in jellyfin

[BigTomm]

I bought a copy of Godzilla Minus One in my recent visit to japan and I'm trying to add it to my jellyfin server with english subtitles. I was able to do so with an ASS file I found online and I added it successfully using mkvtoolnix. On my computer, the subtitles work great. But when I added Godzilla Minus One to my server it doesn't show the subtitles at all. It also pops up as "undefined" subtitles which didn't matter on my computer but it might on jellyfin? All help is greatly appreciated!

What Jellyfin client(s) have you tried?

Can you run ffprobe on the movie and share the output here?  Preferably a text file attached to your post.  Same with the "Media Info" from the Jellyfin UI.  Paste the Media Info in a text file and attach it to a post.

Here is the media info. I'll get back to you with the ffprobe once I figure out how to do that haha. I've tried the website and the ios client with it.

Looks like you are using Linux.

On the command line

Code:

/usr/lib/jellyfin-ffmpeg/ffprobe "/Media/Movies/Godzilla Minus One (2023)/Godzilla Minus One.mkv"

It's "undefined" because you didn't give it a name when you muxed the subs in.

Did you try Jellyfin Media Player? That uses MPV which plays ASS subs fine.

What are the subtitle settings for your client set at?

Sorry for the long wait. Something hectic came up. I have not tried the media player mainly because I've been too lazy to install it but I'll get on that. I do have infuse and it works fine on there. My subtitle mode is set to default and the burn subtitles is set to auto. I saw that ASS is considered a complex type, do you think it would be a good idea if I got different subtitles on that weren't ASS?

Try setting the "burn in all complex subs" on. Maybe your browser just doesn't support ASS subs.

As for your other question, it looks like it also has PGS subs.

For me srt files are the way to go. Most players can play them without having to transcode. Also, you can leave them as external files in Jellyfin, no need to mux it into the file. You just need the proper naming scheme with flags (ex. below).

Path: /Media/Movies/Godzilla Minus One (2023)/Godzilla Minus One.mkv
Path: /Media/Movies/Godzilla Minus One (2023)/Godzilla Minus One.en.forced.srt

When you say it can be an external file, does that mean add the SRT to the Godzilla Minus One folder as well as the mkv and then rename the mkv and to Godzilla Minus One.en.forced.srt and it should work?

[TheDreadPirate]

Yes. You add the SRT file to the folder and give it the same name as the movie, except with the srt extension. There are additional parameters in the file name, like the language (en) and disposition (forced) that Efficient included.

Here is out documentation on external files, not limited to just subtitles.
