title: How to put the Camera input on the screen and blur it?
body: <p>I'm fairly new to iOS development.</p>
  
  <p>What I want to achive is to put the stream from the camera in a UIView class. (and size it with a frame).
  So i don't need controls or the possibility to capture images, just on the screen what the camera sees.</p>
  
  <p>Furthermore, i want that view to be blurred. Is there a way (or a library) to put a gaussian blur on that videostream?</p>
  
  <p>Thank you!</p>
