title: Video Streaming and Broadcasting using WebRTC
body: <p>I am very new to Real Time Protocols and I had some questions about how WebRTC works and how I can implement it. I am trying to create a one to many livestream like facebook or periscope, where one user broadcasts and other users join and stream the video. I am using Swift from my client end.</p>
  
  <p>My questions are: </p>
  
  <ol>
  <li>How do I broadcast a video using WebRTC</li>
  <li>Is there an SDK for WebRTC in Swift/iOS</li>
  </ol>
  
  <p>I know the questions are very vague but a guidance to the right direction would be great because I am not sure where to start</p>
