Which kind of video are you streaming? If it is MPEG4, the ES that you
dump will not contain the "global headers" (they are contained in the
config line in the SDP).

If the video is MPEG4, you cannot simply dump the packet payload into a
file and play the file, but you also have to fill the AVCodec extradata
witht the global headers extracted from the SDP.
