I'm no video rendering wiz so this may be an easy knock-down...
With my setup I just used QuickTime to export a video created with the web-cam at 1080p. In the Export option I had the tick-box for HEVC encoding - not greyed-out or similar - and though it took a little time the export went ok. Saved about 8MB from a 58MB mov video.
iTunes plays DRM videos fine.
No Shiki but I do have Whatevergreen.
System Definition = iMac14,2 (as we discussed previously etc)
No other kexts except the NoVPAJpeg one for Preview etc.
Not sure that's of any use but just noticed while recording a podcast.
From my trial and error, I think the issue is how your system is setup to use the internal graphics card + egpu.
For my RX560, to get DRM working correctly, Intel needs to be disabled. I can do it through BIOS or enabling "Inject Intel" using the new Whatevergreen (you're no supposed to need "Inject" so turning it on disables the card). Then it runs like a native Mac so streaming, iTunes extras, and downloaded content plays.
However, without the internal graphics, hardware acceleration is disabled. So Final Cut and other programs see a big hit in rendering performance.
If I enable the internal graphics using Whatevergreen (no "Inject Intel"), then hardware acceleration is active. But, that cancels out some of the DRM playback features like streaming.
It's worth noting I've tried both Nvidia and AMD (in High Sierra) and the behavior is similar only Nvidia never worked with streaming and was unstable when internal graphics were active.
So I'm left guessing that iTunes may be getting confused and using the wrong video card when internal graphics are on. I know Shiki has values you can use to change some of this behavior but I'm not sure its the answer.
