Is it not obvious from this error what the problem is?  Obviously, you are not calling "MPEG4GenericRTPSink::createNew()" correctly.  Look at "liveMedia/include/MPEG4GenericRTPSink.hh", and you will see why your call to "MPEG4GenericRTPSink::createNew()" is incorrect.

You need to pass more parameters to "MPEG4GenericRTPSink::createNew()".  Specifically (using the example code in "ADTSAudioFileServerMediaSubsession.cpp":

	MPEG4GenericRTPSink::createNew(envir(), rtpGroupsock, 96, adtsSource->samplingFrequency(), "audio", "AAC-hbr", adtsSource->configStr(), adtsSource->numChannels());
 
where "adtsSource" is a "ADTSAudioFileSource" that you have previously created by:
	ADTSAudioFileSource* adtsSource = ADTSAudioFileSource::createNew(envir(), inputFileName);
