<p class=MsoNormal><font size=3 face="Times New Roman"><span lang=EN-US
style='font-size:12.0pt'>The basic problem is your code's use of the port
number 8556. First, you shouldn't think of it as being the server's
'output' port. Instead, it's the 'control' port that the server uses for
incoming RTSP connections from clients. (The actual RTP/RTCP stream
'output' uses other port numbers, which will differ for each client.)<o:p></o:p></span></font></p>

<div>
<p class=MsoNormal><font size=3 face="Times New Roman"><span lang=EN-US
style='font-size:12.0pt'>Anyway, the key point is that because the server uses
port number 8556 for RTSP, your code can't reuse it.<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=3 face="Times New Roman"><span lang=EN-US
style='font-size:12.0pt'>Also, you should not be calling
"getStreamParameters()" and "getStreamSource()" at all.
Those functions are only used internally by our library code to implement
RTSP server functionality; you should not be calling them yourself in your
code.<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=3 face="Times New Roman"><span lang=EN-US
style='font-size:12.0pt'>Because your server is receiving Transport Stream
packets on a UDP port (1236, in your case), and then re-serving this data via
RTSP, you should just be using a variant of the code that's used (in lines
330-356 of "testProgs/testOnDemandRTSPServer.cpp") to demonstrate
this functionality in the "testOnDemandRTSPServer" demo application.<o:p></o:p></span></font></p>
