The first two videos are working correctly. Video 3 works, but sometime the framerate drops down. Video 4 doesn’t work properly.
So I think that a 1080p x265 video can be played if it has an avg bitrate up to 2Mbps.
=== VIDEO 1 ================================================
This doesn’t work (which I didn’t think it would with a bitrate of 9k) - lots of audio dropouts and major video lagging - but for the few seconds it plays before buffering, it looks absolutely gorgeous!

It’s definitely a hardware limitation of the Apple TV – the Apple TV 4 doesn’t support HEVC natively. Your HEVC videos play fine on Plex because your Plex Media Server is transcoding them to h.264 before streaming them to the Apple TV. Infuse doesn’t rely on a transcoding server, and transcodes things locally on the Apple TV. Transcoding HEVC in software is very CPU-intensive, and presumably the computer hosting your Plex Media Server has a more powerful CPU than the Apple TV.
Just tried a 10GB 1080p x265 MKV w DTS and found that there was noticeable stuttering, but otherwise reasonable playback.
At least as good as the other media players on the atv market… Who knows if we’ll ever get support on the A8 chip?
Might need to wait for the dust to settle on the technology and to get some hardware decoding
