vaapisink overlay

[imeshns]

Hi,

I use example from the internet and when I'm using glimagesink everything is
ok, but when I use vaapisink the overlay does not work correct, only black
screen. When I use gst-inspect with vaapisink it's ok, but Gtk overlay does
not work.
What's wrong?
Thanks for all help.

My code:

#include <gst/gst.h>
#include <gst/video/videooverlay.h>
#include <gtk/gtk.h>
#include <gdk/gdk.h>

#if defined (GDK_WINDOWING_X11)
#include <gdk/gdkx.h>
#elif defined (GDK_WINDOWING_WIN32)
#include <gdk/gdkwin32.h>
#elif defined (GDK_WINDOWING_QUARTZ)
#include <gdk/gdkquartz.h>
#endif

static void realize_cb (GtkWidget *widget, GstElement *sink)
{
	GdkWindow *window = gtk_widget_get_window (widget);
	guintptr window_handle;

	if (!gdk_window_ensure_native (window))
		g_error ("Couldn't create native window needed for GstXOverlay!");

	#if defined (GDK_WINDOWING_WIN32)
		window_handle = (guintptr)GDK_WINDOW_HWND (window);
	#elif defined (GDK_WINDOWING_QUARTZ)
		window_handle = gdk_quartz_window_get_nsview (window);
	#elif defined (GDK_WINDOWING_X11)
		window_handle = GDK_WINDOW_XID (window);
	#endif

	gst_video_overlay_set_window_handle (GST_VIDEO_OVERLAY (sink),
window_handle);
}

int main (void)
{
	gst_init (NULL, NULL);
	gtk_init (NULL, NULL);
	GError *error = NULL;
	
	GstElement *pipeline, *sink;
	
	GtkWidget *windowHead = gtk_window_new(GTK_WINDOW_TOPLEVEL);
	GtkWidget *video_window;
	
	pipeline = gst_parse_launch ("rtspsrc latency=5 drop-on-latency=true
protocols=1 location=rtsp://x.x.x.x ! rtph264depay ! h264parse !
vaapidecodebin ! vaapisink name=sink", &error);	
	sink = gst_bin_get_by_name (GST_BIN (pipeline), "sink");
	
	video_window = gtk_drawing_area_new ();
	g_signal_connect (video_window, "realize", G_CALLBACK (realize_cb), sink);
	
	gtk_container_add (GTK_CONTAINER (windowHead), video_window);
	gtk_window_set_default_size (GTK_WINDOW (windowHead), 800, 600);

	gtk_widget_show_all (windowHead);	
	gst_element_set_state (pipeline, GST_STATE_PLAYING);
	
	g_print ("Now playing...\n");
	
	gtk_main();
	
	return 0;
}
