title: Time stamps of RTP\H.264
body: <p>I have a question about I,P,B frames and their time stamps. </p>
  
  <p>I know that the timestamp of RTP packets suppose to be increased monotonically. 
  I also know (correct me if I'm wrong) that in h.264 <code>B_5</code> frame can be transmitted before <code>P_4</code> frame but displayed after (P_4 and then B_5) so the decoder will use the B frame to decode the P frame.</p>
  
  <p>I have pcap capture of RTP\H.264 stream and I can see that the time stamps  increases\decreases... and not monotonically increases.</p>
  
  <p>So my question is what values the RTP packets (I,P,B frames) should get on h264 transmission? </p>
  
  <p>I will be happy for some clarification about that matter.</p>
  
  <p>Thanks.</p>
