Yes, you will need to write a new subclass of "FramedSource", and use this 
(instead of "ByteStreamFileSource").

See <http://www.live.com/liveMedia/faq.html#liveInput>.

Also, because you wish to stream unicast (presumably on-demand, from a RTSP 
server, as is done by the "testOnDemandRTSPServer" test program), you will 
also need to write a subclass of "OnDemandServerMediaSubsession" that 
implements the virtual functions:
         - createNewStreamSource() (which will create an instance of your 
new "FramedSource" subclass), and
         - createNewRTPSink()

You will probably also want to set the "reuseFirstSource" parameter (to the 
"OnDemandServerMediaSubsession" constructor) to True, so that your input 
buffer is read only once, regardless of how many concurrent clients you have.
