your code confusing... show error related mycam, mycam commented out!

let's assume error has cam variable. have defined cam?

     private var cam:camera;       //or      var cam:camera = camera.getcamera();

check example @ bottom of page attachcamera()

following code...

     private var participantvideo:video = new video( 160 , 120 );       //later in function      participantvideo.attachcamera( cam );
