hi  
image() method has some problems about open file .mp4  
other example can open same video file but in my coding doesn’t work  
can you help me?

this is my coding

import processing.video.\*;

import com.hamoid.\*;

int cellSize = 10;  
int cols, rows;  
float secondsnb;  
int imagesnb;  
int seconds2;

Capture cam1;  
Capture cam2;  
VideoExport videoExport;  
Movie timeLapse;  
PImage img1;  
PImage img2;  
PImage pg;

//font  
PFont f;  
PFont g;  
int fontS = 80;  
int fontT = 20;  
int fontA = 255;  
int count = 0;  
int countObs = 0;

void setup() {  
String[]cameras = Capture.list();  
printArray(cameras);  
//fullScreen(2);  
size(1600, 900);  
frameRate(30);  
cols = width / cellSize;  
rows = height / cellSize;  
colorMode(RGB, 255, 255, 255, 100);

cam1 = new Capture(this, 1600, 900, cameras[1], 30);  
cam2 = new Capture(this, 1600, 900, cameras[2], 30);

f = createFont(“Berlin sans FB BOLD”,fontS);  
pg = cam2;

```
background(0);

```

}

void captureEvent(Capture c){  
if (c == cam2){  
cam2.read();  
}  
}

void movieEvent(Movie m){  
if( m == timeLapse){  
timeLapse.read();  
}  
}

void draw() {

if(secondsnb == 0){  
videoExport = new VideoExport(this, “data/camera.mp4”,pg);  
videoExport.setGraphics(pg);  
videoExport.startMovie();  
cam1.start();  
cam2.start();  
}

secondsnb++;  
if (secondsnb %5 == 0 && secondsnb \<= 100) {  
imagesnb ++ ;  
pg = cam2.get();  
videoExport.saveFrame( );  
}  
if(imagesnb \>= 20){  
videoExport.endMovie();  
cam2.stop();  
timeLapse = new Movie(this, “camera.mp4”);  
//break;  
}  
if (cam1.available() && secondsnb \<= 100) {  
cam1.read();  
cam1.loadPixels();

```
for (int i = 0; i < cols; i++) {
  for (int j = 0; j < rows; j++) {
  
    int x = i*cellSize;
    int y = j*cellSize;
    int loc = (cam1.width - x - 1) + y*cam1.width; 
    float r = red(cam1.pixels[loc]);
    float g = green(cam1.pixels[loc]);
    float b = blue(cam1.pixels[loc]);       
    color c = color(r, g, b, 75);  
    pushMatrix();
    translate(x+cellSize/2, y+cellSize/2);
    rotate((2 * PI * brightness(c) / 255.0));
    rectMode(CENTER);
    fill(c);
    noStroke();
    // Rects are larger than the cell for some overlap
    rect(0, 0, cellSize+6, cellSize+6);
    popMatrix();
  }
}

```

}  
if(secondsnb / 100 == 1){

}

here is error
