Hi all -

Trying to work with the camera and I occasionally get this error..   SGIdle failed in icvGrabFrame_QT_Cam with error -1
What can I disable with QT so that the camera may be reliably accessed with processing?  Thank you

code:

1. import hypermedia.video.*;
   import java.awt.Rectangle;
   boolean foundIt;
   int timer;
   
   
   OpenCV opencv;
   
   // contrast/brightness values
   //int contrast_value    = 0;
   //int brightness_value  = 0;
   
   
   
   void setup() {
   
       size( 640, 480 );
   
       opencv = new OpenCV( this );
       opencv.capture( width, height );                   // open video stream
       opencv.cascade( OpenCV.CASCADE_FRONTALFACE_ALT );  // load detection description, here-> front face detection : "haarcascade_frontalface_alt.xml"
   
   
   }
   
   
   public void stop() {
       opencv.stop();
       super.stop();
   }
   
   
   
   void draw()
   {
     
   
       opencv.read();
   
   
       // proceed detection
       Rectangle[] faces = opencv.detect( 1.2, 2, OpenCV.HAAR_DO_CANNY_PRUNING, 40, 40 );
       foundIt=true;
   
       // display the image
      
       image( opencv.image(), 0, 0 );
      
   
       // draw face area(s)
       noFill();
       noStroke();
   
       for( int i=0; i<faces.length; i++ )
       {
          rect( faces[i].x, faces[i].y, faces[i].width, faces[i].height );
       
             if (foundIt==true){
                 timer=millis();
                 println(timer);
         } else if( foundIt==false)
           {
             if (millis()-timer>=50000)
                 {   
                   //Do something
                   println("buzz");
                 }
           } 
       }
   }
