Replay at wrong speed/framerate

[Robin Aproskie]

Hi 

I am recording an (UDP (RTP (h.264 ) ) ) stream. It streams 50 frames per second interlaced. When I play it back it seems to play at half the speed ie 25 frames per second and takes twice as long to play.
The time stamp info seems to match the duration = 40000000

*******The Record Pipeline Is

 	pipeline2 = gst_pipeline_new ("REC-pipeline");
	source2 = gst_element_factory_make ("udpsrc", NULL);
	rtpdepay2 = gst_element_factory_make ("rtph264depay", NULL);
	caps = gst_caps_from_string("application/x-rtp,"
		"media=(string)video,"
		"clock-rate=90000,"
		"encoding-name=(string)H264,"
		"sprop-parameter-sets=(string)\"J2QAKKwXKgLQSZAA\\,KP4BriwA\"," /*"sprop-parameter-sets=(string)\"J2QAKqwXKgFAFuQA\\,KP4BriwA\","*/
		"payload=(int)96,"
		"framerate=(string)50/1");
	g_object_set (G_OBJECT (source2), "caps", caps, NULL);
	g_object_set (G_OBJECT (source2), "address", videoIpAddress, NULL);
	g_object_set (G_OBJECT (source2), "port",  m_ipPortVideo, NULL);
	g_object_set (G_OBJECT (source2), "buffer-size", 65000, NULL);
	g_object_set (G_OBJECT (source), "multicast-iface", multicastIF, NULL);
	
	filtercaps = gst_element_factory_make("capsfilter","filter"); 
	caps264 = gst_caps_new_simple ("video/x-h264", \
						 "stream-format", G_TYPE_STRING, "byte-stream", \
						 "alignment", G_TYPE_STRING,"nal",NULL, \
						 "framerate",GST_TYPE_FRACTION, 50, 1, NULL);
	             
	g_object_set (G_OBJECT (filtercaps), "caps",caps264, NULL);

	filesink = gst_element_factory_make ("filesink", NULL);
	
	g_object_set (G_OBJECT (filesink), "location", "c:\\video.h264", NULL);
	
	gst_bin_add_many (GST_BIN (pipeline2),source2 \
											,rtpdepay2
											,filtercaps \
											,filesink \
											,NULL);

	gst_element_link ( source2 ,rtpdepay2 );
	gst_element_link (rtpdepay2 ,filtercaps);
	gst_element_link ( filtercaps ,filesink);

******The play pieline is

	qStringToGchar("c:\\video\\" + dirName + "\\" + fileName + ".h264",location,100);
	
	source = gst_element_factory_make ("filesrc", NULL);
	
	g_object_set (G_OBJECT (source), "location", "c:\\video.h264", NULL);
	h264parse = gst_element_factory_make ("h264parse", NULL);
	queue = gst_element_factory_make ("queue", NULL);
	avdec = gst_element_factory_make ("avdec_h264", NULL);
	queue2 = gst_element_factory_make ("queue", NULL);	
	
	/* Adaptors needed because cairooverlay only supports ARGB data */
	autovideoconvert2 = gst_element_factory_make ("videoconvert", NULL);
	
	cairo_overlay = gst_element_factory_make ("cairooverlay", "overlay");

	/* If failing, the element could not be created */
	g_assert (cairo_overlay);

	/* Hook up the neccesary signals for cairooverlay */
	g_signal_connect (cairo_overlay, "draw", G_CALLBACK (draw_overlay3), overlay_state);
	g_signal_connect (cairo_overlay, "caps-changed",G_CALLBACK (prepare_overlay), overlay_state);
	
	sink = gst_element_factory_make ("d3dvideosink", NULL);
