[Live-devel] multicast issues on windows xp?

[Alessandro Gaiarin]

Hi,

 

I wonder if somebody can help here.. Basically, have a WAV streamer using
mutlicast. In this context have two sockets for the RTP and RTCP protocols
on two different ports (RTP port <n>, RTCP port <n+1>), same multicast
address. Now, I'm working on the client side and have observed that the
client is not receiving any data from the RTCP port (well, have noticed that
my client didn't see the termination of the audio stream  (i.e. RTCP BYE
packet not received!). However, it does receive data from the RTP port. Have
Even running the test applications testWAVStreamer and openRTSP I'm
experiencing the same problem. Have installed a TCP/IP snooper and can
actually see UDP packets coming from the server RTP and RTCP ports.
Debugging the code, the select gets only awaken for network data coming from
the RTP port. Is there any known issues re multicast or tcp/ip stack on
Windows XP? Or, should I define two different mutlicast addresses for RTP
and RTCP? is there something wrong with the Windows XP configuration??

 

I'm using liveMedia source code downloaded a month ago (20/09)

 

Thanks a million,

 

 

Alessandro
