DTS + Subtitles = Video Transcoding

[FordGuy61]

Does your TV run Tizen 5.5?

• Plex uses the HLS protocol to stream to Tizen 5.5 TVs
• HLS has problems with subtitles when Direct Streaming, so they must be burned in to the video stream.
• If the audio is transcoding, then Plex is direct streaming.
• Samsung TVs do not support dts audio. Therefore it is transcoded.
• Result: dts + subtitles = transcoded video. The same thing happens with TrueHD audio.

See post linked below.

Note: Enabling image based subtitles, PGS & VOBSUB, forces a video transcode, irrespective of the audio stream or Tizen version.

Two Tizen Samsung TV's - one works with subtitles (srt), one doesn't

Tizen 5.5 uses HLS vs Tizen 5.0 that uses DASH. Streaming subtitles are an issue in HLS when not direct playing, so it needs to be burned in. Unfortunately a bug on Samsung’s side is preventing us from using DASH for Tizen 5.5, so until that’s fixed by them, we’re stuck.
