EDIT:
More info. I have now tried FFmpeg 4.1.4 and with this version it does work fine.
So it seems it is a regression bug introduced after 4.1.4 (4.2 does not work anymore)

And some more info:
When you set the -pix_fmt to yuv422p it works fine.
Also for yuv420p10le (10bit) it works fine.

It's only for yuv420p it does not work.

And some more important info. :-)

It seems the older FFmpeg versions dropped a warning when YUV420P is not possible with hevc_videotoolbox and converted it automatically to NV12.

Incompatible pixel format 'yuv420p' for codec 'hevc_videotoolbox', auto-selecting format 'nv12'

This is not the case anymore with the current FFmpeg versions.
If you set the pixel format to YUV422P, the warning also pops up but the auto switching to NV12 is done correctly.

Basically the fix is easy: do let the warning popup again when the pixel format is set to YUV420P (which is btw the default pixel format when you do not set -pix_fmt )
