GstRtpBin Elemenst Signal "on-timeout"

Hi All,

I am using GstRtpBin element in the gst-plugins-bad-0.10.8 for implementing

rtsp/rtp streaming over udp. I am able to stream properly. Both SR and RRs are

getting transfered. But when the client stops because of any reason(crash, power

failure, network disconnection, etc) without giving a TEARDOWN signal, the

server should also stop streaming. I have attached a signal handler for the signals

on-timeout, on-bye-timeout, on-bye-ssrc emitted by the gstrtpbin element. But the

signal handlers are not getting called. Following is the sample code for the above

implementation:-

------------------------------------------------------------------------------------------------------------------------------------

void on_bye_ssrc (GstElement* object,
                                       guint arg0,
                                       guint arg1,
                                       gpointer user_data)
{
        printf ("\n\n######### Inside on-bye-ssrc() callback function#########\n\n");
}

void on_bye_timeout (GstElement* object,
                                       guint arg0,
                                       guint arg1,
                                       gpointer user_data)
{
        printf ("\n\n#########Inside on-bye-timeout() callback function#########\n\n");
}

void on_timeout (GstElement* object,
                                       guint arg0,
                                       guint arg1,
                                       gpointer user_data)
{
        printf ("\n\n#########Inside on-timeout() callback function#########\n\n");
}

int main (){

---

g_signal_connect (pstGstRtpBin, "on-bye-ssrc", G_CALLBACK (on_bye_ssrc), NULL);
g_signal_connect (pstGstRtpBin, "on-timeout", G_CALLBACK (on_timeout), NULL);
g_signal_connect (pstGstRtpBin, "on-bye-timeout", G_CALLBACK (on_bye_timeout), NULL);
---

---

}

------------------------------------------------------------------------------------------------------------------------------------

Please suggest how to attach the signal handlers.

Re: GstRtpBin Elemenst Signal "on-timeout"

Hi, gstreamer-devel:

1. If the client crash/power failure/network disconnected, there is no way to send TEARDOWN to server so the server will keep sending packets to the client. I think there is no way to notify server stopping the streaming.

2. on-bye-timeout, on-timeout will be emitted by GstRtpBin if bye packet is received or there is no any packets received for a while. I noticed you mentioned "TEARDOWN", so I think maybe you're playing a RTSP movie and so rtspsrc maybe is used in your pipeline. Rtspsrc uses GstRtpBin internally and connects these signals then do the EOS logics. So I am surprised you have a GstRtpBin element in your pipeline and wanna connect these signals manually. Paste your pipeline here, maybe it can make things clear.

Re: GstRtpBin Elemenst Signal "on-timeout"

Hi Eric,

Thanks for the reply. The rtspsrc element you mentioned is probably a RTSP Client. But i am implementing a RTSP Server. The pipeline i am using is a general pipeline we use for implementing gstrtpbin as a RTP sender. The pipeline is as below :-

gst-launch-0.10 gstrtpbin name=rtpbin filesrc location=<filename> ! mpeg4videoparse ! rtpmp4vpay ! rtpbin.send_rtp_sink_2 rtpbin.send_rtp_src_2 ! udpsink port=5000 host=<IP> name=vrtpsink rtpbin.send_rtcp_src_2 ! udpsink port=5001 host=<IP> sync=false async=false name=vrtcpsink udpsrc port=5005 name=vrtpsrc ! rtpbin.recv_rtcp_sink_2

Please suggest on how to implement the "time out" when the client crashes.

Regards

Aniruddha
