Plex streaming with 4k hevc doesn't work with subtitles

[Enquiries]

Hello



I have Synology DS1821+ and I am running Plex with PlexPass.

I have 4K content mostly HEVC, HDR10 and in a .mkv container.

When I try to play on my TV (LG C1) it automatically transcodes video to H264. That is hurting the CPU so I don’t want to do this.

I find out that’s the case when I try to watch a video with subtitles on and when I turn it off it streams normally (without transcoding it).

I can watch English movies without subtitles, my sister needs English subtitles and my brother needs Slovenian subtitles because he doesn't speak English, so I need 2 subtitles in every movie.

What is the best option for me without having 3 editions of each movie with "burn in" subtitles?

Transcoding it all to H264?

Can you please help me?



Thank you for every answer.

Luka

Yes, subtitles will initiate transcoding. I would recommend streaming via DLNA, Emby or Jelyfin instead.
