Cannot for the life of me mirror the output images in this code

I am just trying to mirror the images in this looped stopmotion. I tried using scale(-1,1), but it is not working for me, either it does nothing or the output is a black screen. Anyone know what I can do?

Thank you!!

code:

import processing.video.*;

String[] cameras = Capture.list();

Capture myCapture;

int captureFrame = 0;

int playbackFrame = 0;

int captureDelay = 0;

int stopMotionFrame = 0;

int totalFrames = 25;

PImage[] stopMotion = new PImage[totalFrames];

PImage emptyImage = createImage(1280, 480, RGB);

//boolean sketchFullScreen() {

//  return true;

//}

void setup() 

{

  frameRate(30);

  

  size(1280, 960);

println(Capture.list());

  

  

  myCapture = new Capture(this, 640, 480, 30);

  myCapture.start();

  for (int i = 0; i < totalFrames; i++){

          stopMotion[i] = emptyImage;

        }

  //myCapture.stop();

}

void captureEvent(Capture myCapture) {

  myCapture.read();

}

void draw() {

  background(0,0,0);

  image(myCapture, 0, 0, 1280, 960);

     

  // Captures a frame at a time interval.

  captureDelay++;

  if (captureDelay>15){

    captureDelay=0;

    captureFrame++;

      if (captureFrame>=totalFrames){

        captureFrame=0;

        }     

    

  stopMotion[captureFrame] = get(0,0,1280,960);

  }

  stopMotionFrame++;

  if (stopMotionFrame>=totalFrames){

    stopMotionFrame=0;

  }

  image(stopMotion[stopMotionFrame], 0, 0, 1280, 960);

}
