title: getUserMedia() Camera Focus
body: <p>I would like to ask if there is a function for camera focus using getUserMedia? I'm using QuaggaJS project - <a href="https://serratus.github.io/quaggaJS/examples/live_w_locator.html" rel="nofollow noreferrer">https://serratus.github.io/quaggaJS/examples/live_w_locator.html</a></p>
  
  <p>What I would like to do is to have a focus on camera because it is a little blurry and it can't detect the barcode. Does anyone know if it is possible?</p>
  
  <p>Thanks!</p>
