Re: Polycom multicast stream to DSS



The port is specified, but not the group.

If this is the complete SDP, I do not know how it could work as a multicast.

I'm trying to setup a DSS with multiple feeds coming from 6 Polycom VSX 7000e, I've gone ahead and setup each of them to multicast to an IP address of the Darwin Streaming Server. I placed the .sdp files of each one into the \movies folder, the problem I'm running into is that everytime I enter the IP address of the polycom that I want to view I get the exact same one.

The same one of what ?

Which happens to be the first one that I setup as a test, if anyone knows what I'm doing wrong or anything like that I would be grateful for the help!!! Below is what my sdp file looks like, it's coming straight from the sdp file that the polycom creates.

v=0
o=- 133 1 IN IP4 10.3.31.133
s=HOU3101
a=tool:Polycom Viewstation
t=0 0

OK so far.

m=video 16386 RTP/AVP 31
c=IN IP4 10.27.2.72/3

not a multicast group - a unicast address

m=audio 16384 RTP/AVP 0
c=IN IP4 10.27.2.72/3

again, not a multicast group - a unicast address

Since they are the same, you only need one - it should be above the audio / video description.

Have you chosen a multicast group address ? Is the software supposed to do that for you ?

Or is this actually a unicast, in which case you probably want to have 10.27.2.72 point to
each one of your VSX 7000's. And, of course, hopefully you will never be more than 3 hops from the server.



Thanks,

Erick...
