Use to extract potential RTP streams from a pcap into a dedicated file.
pcap_tool uses libpcap (https://www.tcpdump.org/)
e.g. for debian:
apt install libcap-dev
gcc pcap_tool.c -o pcap_tool -lpcap
./pcap_tool [-d] INPUT_FILE
e.g.:
./pcap_tool capture.pcap
pcap_tool will dump the potential RTP streams into separate files with format stream-0x<SSRC>.pcap.
Use -d to print debug messages (very verbose at it applies to most of the packets in the pcap), e.g.
./pcap_tool -d capture.pcap
