    var incoming_stream_id = event.streamid;


    // or

// same code can be used for participants
// it is useful
moderator.onstream = function(event) {
    // got local or remote stream
    // if(event.type == 'local')  {}
    // if(event.type == 'remote') {}


    // or YOUR_VIDEO.src = event.blobURL;
    // or YOUR_VIDEO.src = URL.createObjectURL(event.stream);

// same code can be used for participants
// it is useful but optional
moderator.onstreamended = function(event) {
