I don’t agree that DS918+ processor can’t transcode 4k HEVC 10 bit. It’s not powerful if its using software decoding. But hardware decoding works perfectly. You can check it on this link for the capabilities of Apollo Lake Processors :
I tried Emby with different videos on the same DS918+ and it transcodes 10bit 4k HEVC 60Mbps to 1080p h264 30Mbps perfectly with 25% processor usage.
I love Plex , using it for years and bought Lifetime Plex Pass recently, but they really need to update their transcoder so it can fully use Apollo Lake Processors because obviously Kaby Lake is not needed for 4k HEVC 10 bit.
