[Live-devel] About RTSP Url

[alexkid.live55 at gmail.com]

Thanks for your answer Ross,

I have test this feature with testOnDemandeRTSPServer. I have set up the 
URL of the mpeg4ESVideoTest to 
"rtsp://192.168.1.98:8554/mpeg4ESVideoTest/toto".
And try to stream it with openRTSP : -V option and openRTSP can't find 
the stream:

You find enclosed the outpout of openRtsp :
