This utility takes an input stream containing pcap data and produces two output streams: one with the raw audio packets from the caller, and a second with the raw audio packets of the callee.
It is not meant to be run from a command line shell. Rather, a parent process must spawn it and set up the appropriate input and output pipes. Specifically, the node-pcap-ripper
cloud function performs that function.
usage: ./pcap_ripper [options]
options:
---caller-port UDP port on which caller rtp traffic is received
---caller-pt caller codec payload type
---callee-port UDP port on which callee rtp traffic is received
---callee-pt callee codec payload type
---no-eth-hdr if present, recording file does not have an ethernet header (optional: defaults to expecting an eth header to be present)
all options are required to be provided when the executable is spawned, except for the `--no-eth-hdr` option.
libpcap must be installed on the build system
$ ./bootstrap.sh
$ mkdir build && cd $_
$ ../configure
$ make && sudo make install
