I've started just trying to port some example code made for other libraries to use JMC. When I run the code I just get a black screen. I've read the JMC JDocs, but honestly I find that kind of stripped down documentation difficult to follow. It seems like JMC has a different way of dealing with movieEvent... I think. Or I'm making some sort of ridiculous schoolboy error.

The code I've been toying with at the moment should be recognizable from the processing site:

2. /**

4.  * by Hernando Barragan.  
5.  * Built-in video library replaced with gsvideo by Andres Colubri
6.  * 
7.  * Load a QuickTime file and display the video signal 
8.  * using rectangles as pixels by reading the values stored 
9.  * in the current video frame pixels array.

12. import jmcvideo.*;
13. JMCMovie myMovie;
14. 
    
15. int numPixels;
16. int blockSize = 10;
17. 
    
18. color myMovieColors[];
19. 
    
20. void setup() {
21.   
22.   size(640, 480, P2D);
23.   noStroke();
24.   background(0);
25.   myMovie = new JMCMovie(this,"MGBTR.mov", RGB);
26.   myMovie.loop();
27.   numPixels = width / blockSize;
28.   myMovieColors = new color[numPixels * numPixels];
29. }
30. 
    
31. 
    
32. // Read new values from movie
33. void movieEvent(JMCMovie myMovie) {
34.  myMovie.read();
35.  myMovie.loadPixels();
36.   
37.   for (int j = 0; j < numPixels; j++) {
38.     for (int i = 0; i < numPixels; i++) {
39.       myMovieColors[j*numPixels + i] = myMovie.get(i, j);
40.     }
41.   }
42. }
43. 
    
44. 
    
45. // Display values from movie
46. void draw()  {
47.   for (int j = 0; j < numPixels; j++) {
48.     for (int i = 0; i < numPixels; i++) {
49.       fill(myMovieColors[j*numPixels + i]);
50.       rect(i*blockSize, j*blockSize, blockSize-1, blockSize-1);
