Does someone has a working sample code of a openwebrtc sender or receiver?

Hi,
I tried connecting to the demo.openwebrtc webpage using test_client.c but it doesn't work (it says "Failed to connect to the server").
So I literally haven't a single working sample code for reference and for helping me out with developing my openwebrtc application (I'm trying to build a simple sender/receiver application on linux).
Can someone help me?
