If you are running a sensible operating system (e.g., Unix) that represents 
input devices as files, then you can do this very easily, using the 
existing "testMPEG1or2VideoStreamer" test program as a model, after making 
just two minor changes (to "testProgs/testMPEG1or2VideoStreamer.cpp"):

1/ Uncomment the line
         #define IMPLEMENT_RTSP_SERVER 1
2/ Change the value of "inputFileName" variable from
         "test.mpg"
   to the name of your MPEG input device.

This will give you a RTSP server application that streams the input MPEG 
video stream using RTP multicast.

If, however, you want to instead stream using RTP *unicast*, then you can 
use the "testOnDemandRTSPServer" test program as a model.  (Again, replace 
"test.mpg" with the file name of your MPEG input device.)

(If your operating system does *not* represent input devices as files, then 
you have more work to do: You will need to write your own "FramedSource" 
subclass that encapsulates your input device.)
