  }
  let _video = this.video.nativeElement;
  if (navigator.mediaDevices && navigator.mediaDevices.getUserMedia) {
    navigator.mediaDevices.getUserMedia({ video: true, audio: true })
      .then(function (stream) {
        _video.src = window.URL.createObjectURL(stream);

      });
    }
  }

<video #video width="640" height="480" autoplay></video>

Answer 1

This happens when you dont have any device to capture video or capture audio

try checking if your webcam and your microphone are working fine

Answer 2

Try without "audio: true". Its help for my. (Microphone are not work). And check webcam on other sites. Maybe need check permissions for this page.
