alt Hacker NewsI had this problem, but I fixed it by setting it up so it extracts all embedded subtitles into SRT files, and enabled a setting prevents Jellyfin from serving embedded subtitles.
From what I remember, some clients don't support streaming subtitles, so they must download them completely in advance, when the movie starts, before they start appearing. If you pick embedded subtitles with these clients, Jellyfin must extract the subtitles files immediately, and this takes a while depending on container format, file sizes and server load. External subtitles are faster.

Really? How?
My expectation would be that extracting a subtitle file takes a few seconds at most. If you had to do it on the fly every time you watched anything in your library, it wouldn't matter.
Could you elaborate on how you set it up to extract the embedded subtitles?
