title: What is the best technique to send frames to the server or how does livestreaming work on iOS?
body: <p>As in the current iOS SDK there is no way to get compressed frames from video, how could we implement live streaming like skype did? 
  The only way I see now is: </p>
  
  <ol>
  <li>obtain uncompressed frames from AVCaptureVideoDataOutput</li>
  <li>compress these frames using third-party library</li>
  <li>send frames to server</li>
  </ol>
  
  <p>Are there any other ways to accomplish this task? What libraries can be used for compression and are they compatible with appstore?
  Thanks in advance </p>
