title: how to access HTML5 video decoding functionality?
body: <p>HTML5 has <code>&lt;video/&gt;</code> element that downloads video from server, decodes it and renders. Often if not always they use hardware accelerated decoding (if available). </p>
  
  <p>Is it possible to access just decoding functionality? The reason is that I'm using custom streaming protocol and so on client side I have encoded video stream that I need to decode and render.</p>
  
  <p>Pure JavaScript implementations of video decoder are not applicable unfortunately as they cannot provide sufficient performance. I'm interested in HVEC or h.264 codecs only.</p>
