           Summary: Cannot catch 'have-ns-view' on pipeline for playbin
                    and playbin2
    Classification: Desktop
           Product: GStreamer
           Version: git

// Was reproducedwith code like this :
GstElement* m_pipeline = gst_element_factory_make("playbin2", "pipeline");
GstElement* videosink = gst_element_factory_make("osxvideosink", "vsink");
g_object_set(m_pipeline, "video-sink", videosink, NULL);

GstBus* bus = gst_element_get_bus(m_pipeline);
gst_bus_set_sync_handler(GST_BUS(bus), GstMessageDispatcher,
static_cast<Pipeline*>(this));
g_object_unref(GST_OBJECT(bus));

I never get in my Sync handler message with "have-ns-view". The reason is 
when playbin is trying to use my videosink it calls gst_element_set_state(elem,
GST_STATE_READY) before element has been added to playbin.
(
see: for playbin : gstplaybin.c in func 'get_video_element' (line 868)
     for playbin2: gstplaysink.c in func 'try_element' (line 837)
)
