Screen and audio streaming using one connection/one client

This is a general question regarding the capability of the streaming
technology with red5 server.  I see OpenMeeting uses two
connections/clients to stream audio/video and user screen.:
Client 1- the parent client captures and streams audio/video
Client 2-  captures and streams the user screen.
Is it possible using red5 server to stream screen and audio/video using
just one connection/one client?

Thanks!

One connection is impossible due to screen-sharing is performed using
different client java application
Multiple av streams from flash are possible

Thanks very much Sebastian. Here is what I have understood. Please correct
me if needed.
To broadcast audio and my screen I need two different connections with the
streaming server: one for audio and one for my screen.
The only alternative,  but too costly, is to programatically combine the
two streams and re-stream.
 I assume that will require a process in my pc to combine the two streams
and then send it to the server via one connection right?

Thanks!!

Hi Sonia,

short answer: No it won't be possible.

Long answer: You could trans-code both stream to one stream and re-stream.
But that will be a significant effort in terms of implementation and
computing power later on to process it in real time.

Thanks,
Sebastian
