title: Parsing HEVC Stream for non IDR frames
body: <p>I parsed the HEVC stream with this code (after converting bytes to hex format) </p>
  
  <pre><code>string[] NALunit_string = Regex.Split(fsStringASHex, @"000001|00000001");
  </code></pre>
  
  <p>but after looking at the NAL units types, I can find some with reserved types. Is it normal?</p>
