flip video capture horizontally

franciscoeme

Hello! I have been trying to solve this but I haven´t been able. That has discouraged me and I haven´t done so much in the last months because of that. Can someone help me? this I guess shouldn´t be difficult. I want to flip the image capture horizontally.

THanks!

Normally this line draws the frame of video:

image(video, 0, 0, width, height)

Consider this:

pushMatrix();
translate(width,0);
scale(-1,1);
image(video, 0, 0, width, height)
popMatrix();
