You can use these utilities to test osmux:
1) in one console, run ./osmux-test-input
This listens in port UDP 20000 and convert RTP traffic to osmux
Then, it sends osmux traffic via port UDP 20001
2) in another console, run ./osmux-test-output
This listens in port UDP 20001 and convert osmux to RTP traffic
Then, it sends RTP traffic to UDP port 20002
3) in another console run, nc -u nc -u -l -p 20002
This is the sink, just to avoid ICMP destination unreachable messages
Now you can run replay UDP traffic from one pcap trace that contains
RTP traffic with this tool:
http://1984.lsi.us.es/git/pcap-inject/
Example of command line invocation:
./traffic-inject /home/pablo/rtp-nanobts-2-phones-amr.pcap udp 20000
You can run wireshark in the loopback to make sure osmux is getting back
the traces looking like the original.
The tests also generate output files in AMR that you can validate via
mplayer: /tmp/output.amr and /tmp/input.amr respectively. This is to
make sure there are no reordering or problems of any sort.
