Hi;

This is my sample code ;

if (call_info.state == PJSIP_INV_STATE_CONFIRMED)
    {
        pjmedia_session *si = pjsua_call_get_media_session(call_id);


        const pjmedia_sdp_session *remote_sdp;
        const pjmedia_sdp_session *local_sdp;
        pj_status_t status;
        pjsua_call *call;
        pjsip_dialog *dlg;
        char *lvlcip;
        char *rvlcip;

        int lvlcport;
        int rvlcport;

        status = acquire_call("on_call_state()", call_id, &call, &dlg);
        if (status != PJ_SUCCESS){
        printf("acquire call edemedik\n\n");
        }

        status = pjmedia_sdp_neg_get_active_remote(call->inv->neg,
&remote_sdp);
        if (status != PJ_SUCCESS){
        printf("Remote SDP alamadık\n\n");
        }
        status = pjmedia_sdp_neg_get_active_local(call->inv->neg,
&local_sdp);
        if (status != PJ_SUCCESS){
        printf("Local SDP alamadık\n\n");
        }

     rvlcip = (char *) malloc ( remote_sdp->conn->addr.slen + 1);
     strncpy(rvlcip,remote_sdp->conn->addr.ptr,remote_sdp->conn->addr.slen);
     rvlcip[remote_sdp->conn->addr.slen] = '\0';
     printf("Remote IP %s \n\n", rvlcip );
     rvlcport = remote_sdp->media[1]->desc.port;



      start_video_encode(rvlcip,rvlcport);




    }

You can catch the port and ip from sdp negotiating..

start_video_encode is using libvlc
http://wiki.videolan.org/LibVLC_Tutorial_086c might give you idea of what
you are trying to do..
