title: Understanding HTML5 Video Tag and streamed Chunks
body: <p>I am trying to understand the HTML5 video tag and how it plays/buffers chunks of streamed data from a WEBM file.</p>
  
  <p>If I break a WEBM file up into say 10 chunks and feed them all into the video tag, the video plays fine. However if I only feed the last 5 chunks into the video tag it doesn't play. 
  I get...</p>
  
  <p>INVALID_STATE_ERR: DOM Exception 11</p>
  
  <p>Are there some bytes at the start of the file that are needed?</p>
  
  <p>Does the video tag need to know the specific location it is at in the video to play it? i.e. the content-range</p>
  
  <p>How can I just play a specific chunk(s) of the video?</p>
  
  <p>Thanks</p>
