title: H264 Parsing seq_parameter_set_data : DefaultScalingMatrix4x4Flag, DefaultScalingMatrix8x8Flag
body: <p>I try to parse H265 seq_parameter_data from an  RBSP  data... I use the reference from <a href="http://www-ee.uta.edu/Dip/Courses/EE5359/H.264%20Standard2007.pdf" rel="nofollow">http://www-ee.uta.edu/Dip/Courses/EE5359/H.264%20Standard2007.pdf</a> .</p>
  
  <p>It shows how to parse  at page 40. </p>
  
  <p>But the pseudo-algorithms use data structures such as <strong>ScalingList4x4[ ]</strong>,  <strong>ScalingMatrix4x4Flag[ ]</strong> etc... What are they? Are they constant tables or we fill them? Anybody has knowlegde about it?</p>
