I have a Samsung UA40J6200 which in the manual states it supports H265 HEVC Main Profile Only in .mkv format and container. I am running the latest version of Plex on a Synology 716+ which has a quad core Celeron running DSM 6.1.7-15284.
Every HEVC program I have tried always switches to Transcoding and sends the CPU to 98%. Resulting video won't play smoothly or looks very low res. When I try to set it to Direct Play it tells me the player won't render the content or the mediatype is not supported.
Have tried multiple video files all which were 1920x1080 HEVC encoded at around 2mbps.
Anyone have any clues why it won't direct play?
