rtsp / rtp time rtp delta too big, reset skew

[desjare]

I'm trying to configure my rtsp record stream and after a while (several
minutes), the rtpjitterbuffer complains about the difference in skew.

I do not understand how to configure time in RTP.

I played with the rtpbin new_jitter_callback buffer modes, tried to set the
clock from the example in rtsp-server but nothing seems to do it.

	static void
	new_jitterbuffer_callback (GstElement*  rtpbin,
                           GstElement*  jitterbuffer,
                           guint  session,
                           guint  ssrc,
                           gpointer  udata)
	{
		g_object_set (jitterbuffer, "mode",  0, NULL);
		g_object_set (jitterbuffer, "drop-on-latency",  TRUE, NULL);
	}

What is a good way to do this?
