Description

I'm currently having some issues with the qtKit grabber freezing on a project. It felt very similar in description to:

https://forum.openframeworks.cc/t/video-signal-webcam-freezes/21331/4

so I swapped out the qt grabber with code from:

https://github.com/roxlu/video_capture

and it's been working much better (at least with initial testing). I wonder if the qt kit grabber should be replaced and/or if we should start researching avFoundation grabbers to explore. unfortunately its one of those things where all the IOS code out there dwarfs out osx examples, but there are some good implementations in chrome / and small samples around like:
http://www.juce.com/forum/topic/avfoundation-camera-implementaiton-mac-and-ios-code-included

goodbye 10.6.8 :) hello future.

Research direction

Start by reviewing the existing QtKit grabber and the linked roxlu/video_capture implementation, then compare them with the referenced JUCE AVFoundation camera example. Determine whether replacing the QtKit grabber or adding an AVFoundation grabber is the intended direction; the work is done when a supported macOS video-grabbing approach is agreed and implemented.
