Re : Processing 2.0 video alpha channel

What I tried now:

• I tried to use the same Video twice:  

1.   maskImg = new Movie(this, "001.mp4");
     img = new Movie(this, "001.mp4");
     img.play();
     maskImg.play();
     img.mask(maskImg);

            → no luck (mask() can only be used with an image that's the same size)

• I tried to use the same Movie instance:

1.   img = new Movie(this, "001.mp4");
     img.play();
     img.mask(img);
   

            → no luck, because there wasn't a alpha channel effect. It only displayed the Video itself.

• I created a *.avi File with an alpha channel inside → no luck
• And I tried all this with a *.mov and a *.mp4

BUT: my video is now upside down...

I'm working with Processing 2.0b7.
