Hi I am trying to stream 4K files to my new 2017 Roku Ultra however for some reason both the video and audio content is being transcoded making it impossible to play (constant buffering). Am I mistaken that this should simply direct play?
Probably overlooking something as simple is file incompatibility but just want to be sure. Have not attached logs for now as I would need to read up on how to do so. Apologies if this is needed. Also if the file format below is simply incompatible please help me understand which type of 4K files I should be streaming to plex on Roku for direct play.
When playing the file the Plex server tells me:
Video transcoding HEVC to H264
Video transcoding DCA to AC3
My setup is as follows
Plex Media Server on Synology NAS DS1812+
Plex Media Server version 126.96.36.19902-f54242b6b
Roku Ultra 2017 version
latest plex preview player used on the Roku
4K TV LG 65SJ8500
Source UHD Blu-Ray
Video : HEVC/2160p,Real HDR
Compression: :Bits/(Pixel*Frame) 0.123
Audio : DTS MA 5.1 : Engels
Thanks for you help and please let me know if key info is missing
