[gst-devel] How to specify type of sink or src pad in gstrtpbin

[Thomas Winkler]

Hi,
I've added my little (dirty) test-application.
Sender: Sender.cpp, CRtpSender.cpp, CRtpSender.h
Receiver: Receiver.cpp, CRtpReceiver.cpp, CRtpReceiver.h

Here's a sample of my Signalimplementation for my Sender:

Signal connect:
g_signal_connect (m_gstrtpbin, "pad-added", G_CALLBACK (cb_new_pad), NULL);

Method:
void CRtpSender::cb_new_pad(GstElement* element, GstPad* pad, gpointer data)
{
	gchar* name;

	name = gst_pad_get_name(pad);
	g_print("A new pad %s was created\n", name);
	g_free(name);

	GstPad* rtpudpsinkSrc = gst_element_get_static_pad(m_udpsink_rtp,
"src");
	gst_pad_link(rtpudpsinkSrc, pad);
}


But I never get this signal called (have a look into the source)
I don't know what's wrong in my code...

Greetings,
Thomas
