Slit scanning error...

I keep getting the same error, I'm very very new to programming so I'm unsure of what I'm doing wrong. Help?! I keep getting the message that I can't load the movie file.

import processing.video.*;

Movie myVideo;
int video_width     = 768;
int video_height    = 576;
int video_slice_x   = video_width/2;
int window_width    = 1000;
int window_height   = video_height;
int draw_position_x = 0; 
boolean newFrame  = false;

void setup() {
  myVideo = new Movie(this, "Sequence01_4.mov");
  size(window_width, window_height, P2D);
  background(0);
  myVideo.loop();
}

void movieEvent(Movie myMovie) {
  myMovie.read();
  newFrame = true;
}

void draw() {
  if (newFrame) {
    loadPixels();
    for (int y=0; y < window_height; y++){
      int setPixelIndex = y*window_width + draw_position_x;
      int getPixelIndex = y*video_width  + video_slice_x;
      pixels[setPixelIndex] = myVideo.pixels[getPixelIndex];
    }
    updatePixels();
    
    draw_position_x++;
    if (draw_position_x >= window_width) {
      exit();
    }
    newFrame = false;
  }
}

Have you added the movie file to your sketch? What happens if you load "data/Sequence01_4.mov" instead?

PhiLho

You should put size() at the start of setup(), as recommended in the Reference. And you make it backward: in general, you call size() with numerical values, then you use the built-in variables width and height if needed.
