title: ngx-webcam how to identify if user allowed webcam permission or not - Angular 4+
body: <p>I'm having issue with ngx-webcam plugin in Angular4+, as i'm using this plugin to capture images in my application but when user doesn't allow permission of using webcam then I should make a change from capturing to upload a image from computer or mobile.</p>
  
  <p>In this ngx-webcam plugin we do have, to turn on/off webcam but what i need is to identify if user gave permission or not to use webcame for capturing image.</p>
