title: The maximum size with bytes of one NAL unit
body: <p>I can't find any clue in H.264 spec, anybody can give a clear and simple maximum size regardless of its profile and level?</p>
  
  <p>I'd like to parse H.264 stream, and copy one complete NAL unit buffer to a fixed-size buffer which can hold all bytes of one NAL unit.</p>
  
  <p>Thanks.</p>
