RFC 3640.  

  This packetizer must be fed with an InputStream containing ADTS AAC. 
  AAC will basically be rewrapped in an RTP stream and sent over the network.
  This packetizer only implements the aac-hbr mode (High Bit-rate AAC) and
  each packet only carry a single and complete AAC access unit.
