title: How to add additional value/parameters in RTP header
body: <p>Basically, I am working in the VOIP application and trying to build an app using the WebRTC. I already know complete implementation and details about the RTP header which contains things like</p>
  <pre><code> 1. version
   2. padding
   3. extension
   4. CSRC count
   5. marker
   6. payload type
   7. sequence number
   8. Time Stamp
   9. SSRC
   10. CSRC list
  </code></pre>
  <p>But I want to add additional parameters in the RTP header so that I can send it to another PEER. Also, please do update me how to add information and update the RTP header which is of 12 bytes.</p>
  <p>Here are the files from webrtc native stack.</p>

  </ul>
  <p>How can I insert additional values/Parameters with RTP header in WEBRTC?</p>
