You would need to write a new subclass of "FramedSource" that would read 
and parse a '.3gp2' file to produce - for each call to "doGetNextFrame()" - 
a MPEG-4 audio frame.  (This new class could then be hooked into a 
"MPEG4GenericRTPSink" to stream the MPEG-4 audio from the file.)

You could use "liveMedia/DeviceSource.cpp" as a model for this.

If, however, your file contains video as well as audio, then the solution 
will be more complicated - you will need to write a demultiplexor class 
that generates both audio and video frames.  You could use 
"liveMedia/MPEG1or2Demux.cpp" as a model for this.
