I can generate a RTP h.264 video stream (using gstreamer) and have the
description of that stream in client.sdp. If I use vlc I can view the video
just fine. ex. vlc client.sdp.
I would like to perform the same function in my application using live555.
What are the necessary steps to do so?

it's pocible to receive the SDP file that i created from sap (using sapWatch)
using live555MediaServer?
i tryed, but got 404 not found
i think this can be easy for creating playlist & simplifying Multicast access

Sorry, but I don't understand your question. The "LIVE555 Media Server" does
not 'distribute files'. It returns a SDP description - in response to a RTSP
"DESCRIBE" command. But what was your

Each ".sdp" file contains a SDP descriptions for the multicast streams that's
sent by the corresponding "test*Streamer" demo application. For example, the
file "testMPEG2Transport.sdp" contains a SDP

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

Again, it sounds like you're trying to reinvent the wheel. The
"OnDemandServerMediaSubsession" class works just fine - you should
just use it (by defining your own subclass). Note the several
examples in the code. You should be using "testOnDemandRTSPServer" -
not "testMPEG4VideoStreamer" -
Sorry, I forgot ask you about SDP file. Now address is correct (0.0.0.0) but
what about port? "m" line of SDP is still using port I specified when I create
groupsock, could I change it? Should I change it? If the first description is
sending broadcast in te same port it will cause a problem.

Hi all,
I created a session with its respective rtpGroupsock & rtcpGroupsock and then
I added another destination using:
rtpPort= new Port(newPort);
rtcpPort= new Port(newPort+1);
destinationAddress.s_addr = inet_addr((char*)newIP);
rtpGroupsock->addDestination(destinationAddress,*rtpPort);
