Late 2014 iMac: some/most HEVC @ 4K do work !!

[loekf]

In Sierra, playing a 4K HEVC file was a no-go.. mostly a stutter fest with severe frame drops.

Well well.. in High Sierra, looks like HEVC 4K files with approx. 30 Mbps (main 10 btw) do work... even in VLC.

I thought that some form of hardware acceleration was a no-go for the Late 2014 iMac with Haswell. Looks like something got a decent speed upgrade.

EDIT: and with INA .. yep.. all is ok.. they play fine
