I would say the format of the frames your FramedSource should deliver  
depends on which Framer you use.
I've made a subclass of FramedSource which encodes MPEG4V frames  
using Ffmpeg in the doGetNextFrame function. It feeds it frames to an  
MPEG4ESVideoRTPSink and from then on i did about the same as in the  
testMPEG4VideoStreamer test program.

in short:

RTPSink* videoSink = MPEG4ESVideoRTPSink::createNew 
(*live555usageEnvironment, rtpGroupsock, 96);
MySubclassFramedSource* liveVideoSource =  
MySubclassFramedSource::createNew(*live555usageEnvironment);  // 
encodes the frames using FFMpeg
MPEG4VideoStreamFramer *videoFramer =  
MPEG4VideoStreamFramer::createNew(*live555usageEnvironment,  
live555VideoSource);
	
videoSink->startPlaying(*videoFramer, live555AfterPlayingFunc, NULL / 
*clientData*/);
