You would need to:
1/ Write a filter that converts raw AAC audio frames into 
LATM-formatted AAC audio frames (i.e., by turning it into an 
"AudioMuxElement"), and
2/ Use "MPEG4LATMAudioRTPSink" (instead of "MPEG4GenericRTPSink") as 
the RTP sink

So, the data chain would become:

ADTSAudioFileSource -> yourRawToLATMFormatFilter -> MPEG4LATMAudioRTPSink
