[gst-embedded] Any API to extract the parent element information?

[Gireesh Kumar M]

Hi All,

Is there any way to extract the parent element information from a gstreamer
element?
I tried it using the following code snippets but none of them worked.


GstElement *elem =
GST_ELEMENT_CAST(gst_element_get_parent(GST_ELEMENT(pad)));
g_print("In element %s\n", gst_element_get_name(elem)); //-------this
displays current element name properly

elem = GST_ELEMENT_CAST(gst_element_get_parent(elem));
g_print("Parent element is %s\n", gst_element_get_name(elem)); //---this
displays pipeline0


elem = GST_ELEMENT_CAST(gst_element_get_parent(elem));  //--this throws the
following error
g_print("Grand Parent element is %s\n", gst_element_get_name(elem));

/*(gst-launch-0.10:488): GStreamer-CRITICAL **: gst_object_get_name:
assertion `GS
T_IS_OBJECT (object)' failed
Caught SIGSEGV accessing address (nil)
Spinning.  Please run 'gdb gst-launch 488' to continue debugging, Ctrl-C to
quit
, or Ctrl-\ to dump core. */


Then I tried,

GstElement *elem =
GST_ELEMENT_CAST(gst_element_get_parent(GST_ELEMENT(pad)));
elem = GST_ELEMENT_CAST(gst_element_get_parent(elem));

GstElementClass *kl = GST_ELEMENT_GET_CLASS(elem);
g_print("In element %s\n",
gst_object_get_name((GstObject*)(kl.details->longname));

This again gave pipeline0, where I'm expecting the actual name of the
element. It would be great if anyone can guide me.

Many thanks in advance,
Gireesh
