hi there !

I use processing video library to read a quicktime movie and

i use openCV library to grap a video from my i-sight.

Via reactivision i want to playback the movie when

i hold a marker into the camera

(but this is not a reactivision problem...)

Most of the code works fine

(video grapping and playing or pausing the movie when a marker appears.)

BUT when Im running the code,

first of all the sound of the movie plays

(means its running without beeing displayed, because theres no marker).

I tried it with for example...

void mousePressed() {

pressed = true;

  myMovie.stop();

}

... and it stops for about 3 seconds,

but then it starts again at the beginning.

Summarized, my problem is that the quicktime file

starts whithout being asked do do that.

once the movie is finnished one time, everything works just normal.

thanks for your help,
