Server Version#: Windows 10 1.21.4.4079 Player Version#: Plex Web 4.51.3 I’m having an issue with hardware transcoding on an 6th Gen Intel cpu and SOME 10-Bit HEVC content. Other 10-Bit HEVC content decodes and plays perfectly. I’ve also tried the non-playing content on a 7th Gen machine and it t…

Just giving this one a bump… it would be so nice to get this sorted. It’s the only issue I have at the moment preventing me from switching to plex completely and moving away from Emby.

In the hope that someone will still give this a look. If for no other reason than the inconsistent behavior of Plex Server on 6th Gen Intel Cpu’s. I have managed to get consistent results now across all content that wasn’t working. If I set “Use hardware accelleration when available” to on and uns…
