The simplest way to do this is to define your own subclass of “RTSPServer”, and - in this subclass - redefine the virtual function “createNewClientConnection()” (which is called each time that a client connects to the server).  E.g.

class myRTSPServer: public RTSPServer {
public:
  static myRTSPServer* createNew(UsageEnvironment& env, Port ourPort = 554,
                               UserAuthenticationDatabase* authDatabase = NULL,
                               unsigned reclamationSeconds = 65) {
    int ourSocketIPv4 = setUpOurSocket(env, ourPort, AF_INET);
    int ourSocketIPv6 = setUpOurSocket(env, ourPort, AF_INET6);
    if (ourSocketIPv4 < 0 && ourSocketIPv6 < 0) return NULL;

    return new myRTSPServer(env, ourSocketIPv4, ourSocketIPv6, ourPort,  authDatabase, reclamationTestSeconds);
  }

private:
  myRTSPServer(UsageEnvironment& env,
             int ourSocketIPv4, int ourSocketIPv6, Port ourPort,
             UserAuthenticationDatabase* authDatabase,
             unsigned reclamationSeconds)
	: RTSPServer(env, ourSocketIPv4, ourSocketIPv6, ourPort, authDatabase, reclamationTestSeconds) {}
myRTSPServer::~myRTSPServer() {}

virtual ClientConnection* createNewClientConnection(int clientSocket, struct sockaddr_storage const& clientAddr) {
	// The client’s IP address is in “clientAddr”; do what you want with it here

	// Then call the original function:
	return RTSPServer::createNewClientConnection(clientSocket, clientAddr);
}
};

Then, in your application code call
	myRTSPServer::createNew( … );
instead of
	RTSPServer::createNew( … );
