Sorry, I was unaware that macOS has no release support.
Apologies, I don't know what you mean by "FFmpeg git head"
> Please test it
I used Homebrew to install FFmpeg - do you mean I should reinstall with
the --HEAD option (per
https://trac.ffmpeg.org/wiki/CompilationGuide/MacOSX#ffmpegthroughHomebrew)
and retry the capture?

This is the complete console with my current "HEADless" install of FFmpeg
3.2.2
