Dumping of RTP/RTCP packets to text2pcap format.
Implementation of a simple helper utility that can be used to dump incoming and outgoing RTP/RTCP packets to text2pcap format. The resulting file can then be passed to the text2pcap
application in order to get a .pcap or
.pcapng file that can be analyzed via Wireshark or similar applications, e.g.:
/usr/sbin/text2pcap -D -n -l 1 -i 17 -u 1000,2000 -t '%H:%M:%S.' dump.txt dump.pcapng /usr/sbin/wireshark dump.pcapng
While plugins are free to take advantage of this functionality, it's been specifically added to make debugging from the core easier. Enabling and disabling the dump of RTP/RTCP packets for the media traffic of a specific handle is done via the Admin/Monitor API so check the documentation of that section for more details. Notice that starting a new dump on an existing filename will result in the new packets to be appended.
