Is there a way to use subtitles extracted via the Extract Subtitles plugin?

Describe the bug
Sorry, not exactly a bug.

I understand that Kodi v21.0 cannot use embedded WebVTT subtitles, but can use external WebVTT subtitles. I ran the Extract Subtitles plugin, thinking this would make the embedded subtitles now external, so Kodi would be able to use them, but I still could not play WebVTT subtitles on Kodi.

To Reproduce

1. Run Extract Subtitles plugin
2. Try to enable subtitles on video
3. Subtitles don't work; Not sure if they're still the embedded subtitles

Expected behavior
Extracted subtitles work on Jellyfin for Kodi

I suspect this has very little to do with subtitle extract and more it being webvtt, which is kinda a niche format and I don't have any in my library to test with. Without trying to track some down to test myself, my guess is that that device profile needs updating to indicate that we can support them. If you'd like to try changing that yourself, this is the location you'd need to update:

jellyfin-kodi/jellyfin_kodi/helper/playutils.py

Lines 444 to 461 in 9fe904f

Thank you, I'll play around with it when I get some extra time.

You can convert vtt to srt with ffmpeg; ffmpeg -i input.mkv -vn -an output.srt.

YouTube (since 2013 according to Wikipedia) and other HTML5 video players use WebVTT for subs, so an easy source for test files is yt-dlp.
