<p><font size="3" face="Times New Roman">Hello Ross</font></p>
<p><font size="3" face="Times New Roman"></font> </p>
<p><font size="3" face="Times New Roman">When I tried the published url in VLC , I was able to get the <strong>createNewStreamSource
</strong>and <strong>createNewRTPSink </strong>calls.</font></p>
<p><font size="3" face="Times New Roman">I have started getting calls to <strong>
doGetNextFrame</strong> of the source class.</font></p>
<p><font face="Times New Roman"><font size="3">But in VLC there is an error "<span style="COLOR: #000000">VLC is unable to open the MRL 'rtsp://192.168.1.164:8554/WaspTest'. Check the log for details"</span></font></font></p>
<p><font size="3" face="Times New Roman"><span style="COLOR: #000000">and in the server side , the
<strong>doGetNextFrame</strong> calls continue.</span></font></p>
<p><font size="3" face="Times New Roman"><span style="COLOR: #000000">What can be the reason of this behaviour ?</span></font></p>
<p><span style="COLOR: #000000"><font size="3" face="Times New Roman">Is it something related to the sink class.I have created instance of SimpleRTPSink class in
