After two years ... I faced this problem yesterday and this is my solution
1/ Change: "videoReader = vision.VideoFileReader('...avi')" by "videoReader = webcam(1)
2/ change " frame = step(videoReader) " by " frame = snapshot(videoReader)
3/ Change the While loop to an infinite loop
4/ Put in the While loop " frame = snapshot(videoReader)
I hope that it will be useful for someone
