title: Grabbing video with RTSP over TCP
body: <p>I want to retrieve some video data from a device with RTSP. </p>
  
  <p>RTSP over UDP works well, but I need it over TCP.</p>
  
  <p>After issuing the RTSP commands, I receive RTPs but I do not how to handle them here.
  The payload is as follows: $[channel - 1 byte][length - 2bytes][data]</p>
  
  <p>The thing is that I receive such packets and sometimes further packets where channel is 10 or 99 etc. </p>
  
  <p>So could anyone please provide some input on how to handle the payload ?</p>
