You should first write your own subclass of "FramedSource" that 
encapsulates your capture device.  (See "DeviceSource.cpp" for a 
model of how to do this.)

Then, you should write your own subclass of "ServerMediaSubsession" - 
that uses your new 'capture device' class (instead of 
"ByteStreamFileSource") - and use this in place of 
"MPEG4VideoFileServerMediaSubsession".
