It is frequently trying all the ports and not being able to bind to any of the odd ports. I haven’t checked Linux, but in QNX I get back the Address already in use error. Netstat doesn’t show the ports being used prior to me running testRTSPClient, though. <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>On QNX, it will frequently work for the first subsession of a session after boot. The 2<sup>nd</sup> subsession usually doesn’t, but I’ve seen both subsessions work at least once. It’s difficult to determine much rhyme or reason.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>I noticed that the code that calls setupDatagramSocket is trying to find sequential port numbers (even for RTP, following odd for RTSP). The trouble seems to be with the RTSP ports. I don’t understand the code well enough to know whether these port numbers have to be sequential because I seem to get the even ports with no problem. Perhaps something is different about the way the socket is set up for RTSP?<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Thanks,<o:p></o:p></p><p class=MsoNormal>Rob<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p></div></body></html>
