when i run this code i have written,

it goes for a while then it freezes on one frame (usually 1 or 50) of the sampled video (Untitled.mov)...

I cannot understand where is the error.

It would be great if someone could help me!

It's a very simple code... when fCount arrives to frame 50 the speed is inverted (-) and changed (randomically). When it arrives another time to 1 the speed becomes (+) and change another time and so on... It should be like a cycle but at some point it freezes!

This is the code

2. import processing.video.*;
3. Movie myMovie;
4. int fCount  =  0;
5. int fr  = 25;
6. int firstRun = 1;
7. float chooseSpeed=1.0;
8. int choice  =  0;
9. 
   
10. void setup() {
11.   size(320, 240);
12.   
13.   myMovie = new Movie(this, "Untitled.mov");
14.   myMovie.loop();
15. }
16. 
    
17. void draw() {
18. 
    
19.   
20.   if(fCount>49){
21. choice   =  1;
22. chooseSpeed  =  random(-5.0,-0.5);
23. }
24. 
    
25. //firstRun checks if this is the first time that draw runs
26. else if(fCount  ==  1 && firstRun  !=  1){
27. choice =  0;
28. chooseSpeed  =  random(0.5,5.0);
29. }
30. 
    
31.   if(choice  ==  0){
32.     fCount++;
33.    }
34.    else if(choice  ==  1){
35.     fCount--;
36.    }
37.    
38. frameRate(int(abs(chooseSpeed)*fr));
39.  myMovie.speed(chooseSpeed);
40. 
    
41.            if (myMovie.available()) {
42.     myMovie.read();
43.    
44.   }
45.   
46.   image(myMovie, 0, 0);
47.   
48.   firstRun = 0;
49.   
50.   //debug
51.   print(fCount);
52.   print("  ");
53.   print(chooseSpeed);
54.   print("  ");
55.   print(choice);
56.   print("\n");
57. }
58. 
    
59. 
    

Thanks
