title: Youtube Video Streaming protocol
body: <p>I was capturing youtube video packets using wireshark. I saw  it was http tunneled over tcp packet. (Even in case of youtube live streaming).</p>
  
  <p>But whatever I know is that youtube uses flash video technology and html5. Again in some websites they mention about DASH protocol.</p>
  
  <p>My question is, what is the exact protocol used by youtube? And how we can interpret the data that I have captured in wireshark? In the capture it is shown as just 'Data'. There is nothing mention as video data or any other things like that.</p>
