The SPS and PPS are contained in the sprop-parameter-sets in the SDP data 
(base 64 encoded).

example: a=fmtp:96 
packetization-mode=1;profile-level-id=4D401E;sprop-parameter-sets=J01AHqkYFAe2ANQYBBrbCte98BA=,KN4JyA==

If you prepend 00 00 00 01 to each of them and prepend to your dump the 
video should play (It would be nice if mplayer would do this automatically).
