const getMedia = require('getusermedia')

 	var stream = streamToDevice(media, 'default')
	
	// create dropdown of available hardware devices
	enumerateDevices().then(function(devices) {
		var select = document.createElement('select');

		devices.forEach(function(d){
			if(d.kind==='audiooutput' || d.kind==='videooutput') {
				var option = document.createElement('option')
	  		    option.value = d.deviceId
	  		    option.text = d.label;
