stop the webcam streaming of getUserMedia without page refreshing [duplicate]

Answer 1

This seems to be a buggy area in Chrome, and the behavior is constantly changing. This seems to work, only if you are connected via http (not https):

var myStream;
function successCallback( stream ) {
    ...
    myStream = stream; // used to close the stream later
}

function closeStream(){
   myStream.stop(); 
   myStream = null;
}

For some strange reason this doesn't work on SSL (https) (Checked on Chrome for Linux, Ver 27 Dev)
