this is a typical video chat example of webrtc with Qt. it developed from google code project webrtc. it also "borrowed" code from webrtc project.(locate in trunk\talk\examples\peerconnection directory)
note: because webrtc project have signal and slot as Qt dose,so there might have some problems to compile this example. to compile this example, you should have: Qt5.3 lib with VS2013(recommend).
