SOLVED: Subtitle extraction

[RxCarmen]

Hi, jellyfin newbie here

Wondering if anyone has a guide on using the subtitle extract plugin. I have installed the plugin and ran it from schedule tasks but it doesnt seem to do anything, the task completes within a second.

Is the plugin meant to extract subs into a separate file? and if so, where are they located? I am mainly trying to extract subs from mkv files with SSA/ASS subtitles to get the andorid app to use directly play instead of transcoding due to subtitles.

my current setup is within docker/container station on a qnap device.

Yes, the plug-in extracts the subtitles, and places them in Jellyfins metadata folder. It is a very simple plug-in that just calls an internal function on every movie or episode in your library

Thanks, is there a specific folder within metadata I should look out for? running the task manually causes it to finish instantly with no new folder creation.

logs show

[INF] [45] Emby.Server.Implementations.ScheduledTasks.TaskManager: Executing "Subtitle Extract"
[INF] [45] Emby.Server.Implementations.ScheduledTasks.TaskManager: "Subtitle Extract" Completed after 0 minute(s) and 0 seconds

It shouldn't ever take 0s unless you don't have any Movies or Episodes in your library.

I have my server set up with the official docker image, my extracted subtitles are under /config/data/subtitles/*/*.srt

Thanks, I will play around with my current setup and find what is causing the plugin to finish quickly.

Just to update, I managed to fix the issue with extraction. Ended up using docker compose to manually define the cache and config locations and I can see the subtitle folder.

last question I have is how do you tell which subtitles are for which media? the subtitle folder contains a number/letter folder with a set of seemingly random value names. Is there a way to link these up with the correct files?

I believe the filenames correspond to the item id in Jellyfin.

[Shadowghost]

If I remember correctly the item IDs are calculated by adding the file pathe to a static string and hasing the result with MD5 or something...

Dumb question, but if you delete the movie through Jellyfin, will the subtitles extracted also be removed? Also, if I delete the movie folder using File Explorer, the subtitles extracted will not be removed then?

Yes and yes. Though if deleted in file explorer Jellyfin won't delete the subtitles until the next scan or if real time monitoring is enabled.
