[Live-devel] sdp file format

It wasn't clear to me from your description exactly how you are 
transmitting the stream that you are trying to receive/play, but if 
you want to receive/play a stream using only a SDP description, then 
the stream must be multicast, not unicast.  I.e., the following line 
in the SDP description is the problem:

>c=IN IP4 0.0.0.0

Does your server support RTSP?  If so, then you should play the 
stream using a "rtsp://" URL, rather than by reading a SDP 
description directly.

If your server doesn't support RTSP, then you will need to change it 
to stream via multicast, and generate a new SDP description that 
contains the IP multicast address in the "c=" line.
