title: WebRTC iOS: Audio/Video stream recording
body: <p>I am trying to record <code>incoming/outgoing</code> <code>audio/video</code> streams in my <code>iOS</code> app that uses <code>GoogleWebRTC</code> pod. so far I haven't found any api that allows us to record <code>Audio/Video</code> streams. I tried to record local video feed from the camera using <code>AVCaptureSession</code>, but doing this freezes the outgoing video stream. this happens probably because multiple <code>AVCaptureSession</code> instances cannot use the same input device.</p>
  
  <p>Is there any other way to record local and/or remote streams from <code>WebRTC</code> in <code>iOS</code>?</p>
