get h264 raw data from rtp stream in *.pcap.
usage: ./hp.mak
then get ./bin/hp
run: ./bin/run.sh will run the test demo.
in run.sh, I write: ./hp 1.pcap 1.h264 1.h264.rl 5002 5004 106 l.txt 1.pcap: the pcap by tcpdump. 1.h264: output h264 raw data file name. 1.h264.rl: output other with frame length
5002: rtp source port. 5004: rtp dest port. 106: rtp payload type. 1.txt: log.
also, it will output lostSeq.txt to test weather this rtp stream is ok.
