<p>In the "testOnDemandRTSPServer" demo application, the TCP is used to initial handshake and UDP is transmit video/audio data.</p>
<p>At the same time, I find the TCP port is fixed and the UDP port will have the dissimilarity according to the client.</p>
<p>Can the UDP port fix same ? </p>
<p>How to do ?<br></p>
