title: How to capture (record) video stream that enters to my browser?
body: <p>Imagine you watch sports live in your browser. It means you receiving a video stream, right? I need to record this stream and save to disk. The problem is that I don't have a clue from where to start. I'm not new to programming, but have a little experience in live video streaming. 
  I see this problem divided into this parts:</p>
  
  <p>1) Parse html page and find live source URL. (? sounds silly, I'm not sure it is easy to find URL)
  2) When I have URL everything else becomes easy. I would use Java for example, to receive and record stream.</p>
  
  <p>So the main problem is to find live source URL. Does anybody know how to do that? </p>
  
  <p>a) From HTML5 video player </p>
  
  <p>b) From flash player</p>
