[gst-rtsp-server] set ports

Is it possible to configure the negotiated rtp ports used to 
send/receive/control audio/video in the gstrtspserver.c?
I have been reading the documentation and in the GstRTSPMediaTrans class 
there is another class GstRTSPTransport with the fields GstRTSPRange   
server_port; I suppose i can define here the port range for the server.

I have created the gstrtspmedia and set the min and max ports, but now 
how do i tell the factory to use that configuration (if this is even 
correct) code bellow.
(Section added

     media =  gst_rtsp_media_new();
     mediastream = gst_rtsp_media_get_stream(media,idx);


Thanks all and regards!
