Is there sample code to set external wl_surface to waylandsink?

[Halley Zhao]

Hi Expert:

  I tried to create a wl_surface/wl_display, then set them to waylandsink, but it fails to playback. if I don't set wl_surface/wl_display to waylandsink, playback works well (it uses the wl_surface created by waylandsink itself).

  so, I seek simple sample code to start with, is there any sample code to set external wl_surface to waylandsink?

 

  I set wl_surface to waylandsink by gst_video_overlay_set_window_handle().

and wl_display is set to waylandsink by gst_element_set_context() as following:

http://gstreamer-devel.966125.n4.nabble.com/Application-did-not-provide-a-wayland-display-handle-td4683750.html

#define GST_WAYLAND_DISPLAY_HANDLE_CONTEXT_TYPE "GstWaylandDisplayHandleContextType" 

GstContext * 

gst_wayland_display_handle_context_new (struct wl_display * display) 

{ 

  GstContext *context = 

      gst_context_new (GST_WAYLAND_DISPLAY_HANDLE_CONTEXT_TYPE, TRUE); 

  gst_structure_set (gst_context_writable_structure (context), 

      "handle", G_TYPE_POINTER, display, NULL); 

  return context; 

} 

thanks.
