This may solve your issue.
while (video.height == 0 ) delay(10); // <-- add
opencv.loadImage(video);
or
if (video.width > 0 && video.height > 0) {//check if the cam instance has loaded pixels
opencv.loadImage(video);
}
I have no idea why this is necessary.
Solved it for my using Processing 3.3.6.
from opencv-processing.
This above two modifications also work for Processing 3.3.7.
