HAVING ISSUES WITH Plex 4K HVEC X265 HDR PLAYBACK on Xbox X

Plex Docker

 

My CPU is a Intel(R) Core(TM) i5-4690K CPU @ 3.50GHz and play 4K HVEC X265 HDR for a minute but then buffer and play HDR like SDR on my Xbox One X. Is it the CPU/Plex ore my Xbox?

Background

My Samsung KW 950 do not have DTS 7.1/DTS-X but ATMOS. My  Xbox trans code DTS-X to ATMOS and the sound is super on no ATMOS 7.1 movies. On my Shield HDR is perfect, work wherry well with ATMOS. But not as good when it comes to DTS 7.1

 

Here a film when I monitor Unraid when use Plex to Xbox One

Hi,

just had a look at your CPU specs: i´m afraid your the CPU of your Plex Server is not powerful enough for transcoding 4K.

It has a Passmark of 7.800, Plex recommends at least a passmark of 13.000 for 4K content.

 

Thank you, much about what I suspected.

But it works on Shield TV. from same server.

Yes, i guess that´s because the Shield can direct play/stream from the Plex server which means no transcoding on the server is required.

During playback, you can check what´s going on on the Plex server. Have a look at status=>now playing in the Plex server web interface.

I guess it says "direct play/direct stream" when the Shield is playing and "transcoding" when the XBox is playing.
