Lagging while trying sto stream 4k full blueray mkv

With the current Tizen app:

  • Enabling image based subtitles, PGS & VOBSUB, forces a video transcode.
  • If the audio is transcoding, enabling text subtitles, SRT, forces a video transcode.

dts, dts-HD MA, and TrueHD audio will transcode, as they are not supported by Samsung.

So, to ensure the best possible playback when playing 4K HDR media

  • Never use PGS or VOBSUB subtitles.
  • If using text subtitles, do not use dts, dts-HD, or TrueHD audio (or any audio that transcodes).

I do not know if anything is different when using the Tizen Preview app.
