You must set "fDurationInMicroseconds" *yourself*, in your 
"H264VideoStreamFramer" subclass.  You set its value when you copy 
the new frame data to the downstream object's buffer - i.e., before 
you call "FramedSource::afterGetting".  You set "fPresentationTime" 
and "fFrameSize" at the same time.  (See "liveMedia/DeviceSource.cpp")
