Subtitle burn-in won't use extracted embeded subtitles

[homelabResearcher]

Are you using the Subtitle Extract plugin or just on-the-fly subtitle extraction?  If you are relying on on-the-fly extraction, install the Subtitle Extract plugin.  It will pre-extract your subtitles and store them in the Jellyfin metadata directory.

I'm using the subtitle extract plugin, and the subtitle can be found under /config/data/subtitles directory, I cant seem to find a setting to choose where to store these subtitle files. In this thread I'm just wondering why ffmpeg is not using these pre-extracted subtitles when burning-in though. If these subtitles can be found under media folders this issue would be gone.
