MiniSAPListener is a small program that listens to SAP/SDP announcements and invokes a shell command for created, removed, or modified sessions. It can be used with MiniSAPServer.
See usage example in this article.
The implementation is based on the PulseAudio RTP module.
Build:
$ make
Install system-wide:
$ make install
Listen to announcements and print them to stdout:
$ ./saplisten -v
Invoke a shell command for every created, modified, or removed session:
$ ./saplisten -c ./test_command.sh
Use custom address and port:
$ ./saplisten -v -a 224.2.127.254 -p 9875
