title: Real-time Transport Protocol is not used in youtube?
body: <p>I came across reading about real time protocol in Wikipedia, which mentions the following :
  "RTP is used extensively in communication and entertainment systems that involve streaming media"</p>
  
  <p>I was curious about this protocol and wanted to see this in wireshark. I thought youtube.com might be using RTP when running videos, but was surprised to see that only TCP packets are being sent when a video is being played. </p>
  
  <p>Can someone please tell another free website which implements RTP, so that I will be able to see it in wireshark. (I am actually wanting to explore network optimization opportunity in my server applications by using RTP, since it is ok to loose a few packets)</p>
