This SDP descripiton is not sent into the packet but can be retrieved by http 
server (add sdp=http://host into the rtp{....} ) or sended via sap (add 
sdp=sap://,name="session name" into the rtp{}). this SDP  can be used by some 
client application like vlc,mplayer, quicktime to get the stream.

The diffrence betwen the first and the last way to stream is that in the first
methode you use mp4 (video and audio) are encapsulate into a MPGE2 TS.
With the second methode the mp4 is streamed as two separated stream.
one for video and another one for audio. The same ip address will be used
but on two different port ( as SDP describe).
