See original GitHub issue

hi @rogerwang the usage of navigator.mediaDevices.getUserMedia makes the process crash

tested on macOS 10.14.6

how to reproduce:

open : https://www.html5rocks.com/en/tutorials/getusermedia/intro/
click Capture

or just execute this script:

var constraints = { audio: true, video: true }; 

navigator.mediaDevices.getUserMedia(constraints)
.then(function(mediaStream) {
  var video = document.querySelector('video');
  video.srcObject = mediaStream;
  video.onloadedmetadata = function(e) {
    video.play();
  };
})
.catch(function(err) { console.log(err.name + ": " + err.message); });
