Handle embedded subtitle streams on WebOS

[ccar30]

Describe The Bug
Just trying to understand the "Fetching addional metadata" for subrip subtitles... When I try to play an mkv file with embedded subrip subtitles the server has to extract the subtitle track first so the player can display the extracted subtitles file. My question is: Is there anything that can be done for the jellyfin-web player to be able to handle the embedded subtitles stream? Or is it a problem with the platform the client is running on?

I'm running Jellyfin server 10.10.3, the client is a wrapper on the web client running on an LG OLED with WebOS (LG firmware 0.3.41)

As seen below, the file contains a subrip stream

I believe this may not be possible on the HTML video player, but you may want to take a look at https://github.com/jellyfin/jellyfin-plugin-subtitleextract to extract subtitles as a task or when new library content is added.
