allright, it gives me many errors:
plazma3:~/ffmpeg# ./ffplay ../pippo.sdp
socket: Address family not supported by protocol

[NULL @ 0xb7e16be8]hmm, seems the headers are not complete, trying to 
guess time_increment_bits
[NULL @ 0xb7e16be8]my guess is 15 bits ;)
[NULL @ 0xb7e16be8]looks like this file was encoded with 
(divx4/(old)xvid/opendivx) -> forcing low_delay flag

and this is looping..
sometimes:
[mpeg4 @ 0xb7e16be8]Error, header damaged or not MPEG4 header (f_code=0)
..
