title: Transmitting additional data with h.264 frames using RTSP over TCP
body: <p>In one of my applications i am trying to implement sending and receiving of H.264 frames encapsulated in an object which has other data types in it as well. The requirement is to transmit these frames using RTSP over tcp. On the receiving side these frames need to be extracted along with the additional data and displyed.
  I have spent considerable time on trying to make this as confirming to the standards as possible but i dont seem to find any specific payload format which talks about passing custom objects in an RTSP session.
  Is using NAL Units my best bet or is there a better solution to this.</p>
