Hi, 

i'm trying to do masks on videos, using for this videos in grayscale, with GLGraphics + GSVideo + processing 1.5.1, but it doesn't run as expected. I can't see what is wrong... Any ideas ?

Here is my code:

2. import processing.opengl.*;
3. import codeanticode.glgraphics.*;
4. import codeanticode.gsvideo.*;
5. 
   
6. GSMovie movie, movie2, movie3;
7. GLGraphicsOffScreen offscreen;
8. 
   
9. GLTextureFilter maskFilter;
10. GLTexture maskedTex;
11. GLTexture imgMask;
12. GLTexture imgTex, tex, tex2;
13. 
    
14. void setup() {
15. 
    
16.   size(1280, 720, GLConstants.GLGRAPHICS);
17. 
    
18.   movie = new GSMovie(this, "/Volumes/SSD1/video_glitch/17_1_2012_at_16_56_20_GLITCH.avi");
19.   movie2 = new GSMovie(this, "/Volumes/SSD1/video_raw/mask.avi");
20.   movie3 = new GSMovie(this, "/Volumes/SSD1/video_raw/17_1_2012_at_17_1_3_PASS.avi");
21.   frameRate (24);
22. 
    
23.   imgMask = new GLTexture(this, 1280, 720);
24.   tex = new GLTexture(this, 1280, 720);
25.   tex2 = new GLTexture(this, 1280, 720);
26.   maskedTex = new GLTexture(this, 1280, 720);
27.   imgTex  = new GLTexture(this, 1280, 720);
28.   maskFilter = new GLTextureFilter(this, "Mask.xml");
29. 
    
30.  offscreen = new GLGraphicsOffScreen(this, 1280, 720);
31. 
    
32.   movie.setPixelDest(tex);  
33.   movie2.setPixelDest(imgTex);  
34.   movie3.setPixelDest(tex2);  
35.   movie.loop();
36.   movie2.loop();
37.   movie3.loop();
38. }
39. void movieEvent(GSMovie m) {
40.   if (m == movie) {
41.     movie.read();
42.   }
43.   if (m == movie2) {
44.     movie2.read();
45.   }
46.   if (m == movie3) {
47.     movie3.read();
48.   }
49. }
50. 
    
51. void draw () {
52. 
    
53.   background(0);
54. 
    
55.   offscreen.beginDraw();
56.   offscreen.clear(0, 0);
57.   offscreen.fill(0, 255);
58.   if (imgTex.putPixelsIntoTexture()) {
59.     offscreen.image(imgTex, 0, 0, 1280, 720);
60.   }
61.   offscreen.endDraw();
62. 
    
63.   imgMask = offscreen.getTexture();
64. 
    
65.   maskFilter.setParameterValue("mask_factor", 0.0f);
66.  maskFilter.apply(new GLTexture[] { tex, imgMask} , maskedTex);
67. 
    
68. // video 1
69.   if (tex2.putPixelsIntoTexture()) {
70.     image(tex2, 0, 0, 1280, 720);
71.   }     
72. // video 2 + mask
73.   if (maskedTex.putPixelsIntoTexture()) {
74.     image(maskedTex, 0, 0, 1280, 720);
75.   }
76. }
