[Live-devel] Multiple unicasts clients for one Framed Source

[Rawling, Stuart]

I have been trying to my rtsp implementation to allow multiple output
streams from one source.

I have a custom FramedSource object which takes input from a external
device, and am using the OnDemanServerMediaSubsession object (a slight
derivation of it).  I am seting the fReuseFirstSource bit to be True, but
when I connect a second stream, the first stream hangs and the second string
never receives video.

Eventually the library starts displaying TCP traffic information ( I turned
on debug to see what was going on).

The behaviour I expected was that both streams would be being sent via
unicast, and the new destination would just be added to the RTPSink¹s
groupsock.  This is what I had understood by reading through the FAQ.

But now after the problems I have had, and by reading through more of this
list (for example: 
<http://www.mail-archive.com/live-devel@lists.live555.com/msg00434.html> ) ,
I am wondering if I need to change my FrameSource implementation to not set
the fReuseFirstSource bit, and instead to duplicate the frame data as it
comes in, and present the frame data to each FramedSource object that
requires it.

I would appreciate any guidance that you may offer.

Stuart
