Hey

Is there a possibility for it to be solved? Why is it only in LG and not others

4K content with srt not working at all

It’s frustrating for me and a lot because my English aren’t my native language im dependent on subtitles.

I don’t know if anybody from plex devs or anything will read this but if u do please fix it 🙏

With the Plex LG SmartTV app, if the media is direct streaming, such as when audio is transcoding, and you enable any subtitle, Plex will transcode the video.

If you have video transcoding disabled, or the server is not powerful enough to transcode the video, playback will fail.

You can monitor playback via [Plex Dashboard](https://support.plex.tv/articles/200871837-status-and-dashboard/#toc-1) → Now Playing to determine if the media is direct playing, direct streaming, or stranscoding.

The root cause lies with the streaming protocol used between the Plex app and the server.

You may want to consider using a different Plex client, such as Android TV, which will direct play subtitles even if the video or audio is transcoding (Ex: Nvidia Shield Pro, Amazon FireStick 4K Max, etc.)

> enable any subtitle, Plex will transcode the video

What are the technical constraints here?

a brief look into the LG developer documentation says it supports WebVTT? can text based subtitles not be sent in this format?
