</span>What I would do is subclass “RTSPServer”, and - in your subclass - reimplement the “createNewClientConnection()” virtual function, as follows:<br>
<br>
ClientConnection* myRTSPServerSubclass::<wbr>createNewClientConnection(int clientSocket, struct sockaddr_in clientAddr) {<br>
// Do whatever you need to do to set the IP TOS field (for “clientSocket”).<br>
<br>
return RTSPServer::<wbr>createNewClientConnection(<wbr>clientSocket, clientAddr);<br>
}<br>
