[Linphone-users] ortp

[Levente]

Hi all,


I'd like to use ortp to get a stream from a Panasonic IP camera. I have small 
problem here. The library segfaults when I first call the 
rtp_session_recv_with_ts () function. I initialize the stack with this code...

int rtp_init(char *ip_adr, int local_port, RtpSession *session)
        {
        bool_t adapt=TRUE;
        int ret;

        ortp_init();
        ortp_scheduler_init();

        session=rtp_session_new(RTP_SESSION_RECVONLY);  
        rtp_session_set_scheduling_mode(session,1);
        rtp_session_set_blocking_mode(session,1);
        ret=rtp_session_set_local_addr(session,ip_adr,local_port);
        if(ret!=0)
                {
                printf("ERRROR!!\n");
                exit(1);
                }
        rtp_session_enable_adaptive_jitter_compensation(session,adapt);
        rtp_session_set_jitter_compensation(session,40);
        rtp_session_set_payload_type(session,0);
        ret=rtp_session_signal_connect(session, "ssrc_changed", 
(RtpCallback)ssrc_cb, 0);
        if(ret!=0)
                {
                printf("ERRROR!!\n");
                exit(1);
                }
        ret=rtp_session_signal_connect(session, "ssrc_changed", 
(RtpCallback)rtp_session_reset, 0);
        if(ret!=0)
                {
                printf("ERRROR!!\n");
                exit(1);
                }
        return 0;
        }


Debugging my code with gdb, I get this.

Any thoughts where I go wrong?
