include the video directive like this:

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

then in your component:

@ViewChild('video') video:any; 
// note that "#video" is the name of the template variable in the video element

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