gst_ghost_pad_new () only generates _proxypad not ghost sink pad

[Vinod Kesti]

Hi,

To add ghost pad you have to create ghost pad to a existing pad and that pad
to be added to the bin. In your code adding ghost pad to bin is missing it
seems.

The code fir that will be some thing like this 
{
  GstElement *bin, *sink;
  GstPad *pad;

  /* init */
  gst_init (&argc, &argv);

  /* create element, add to bin */
  sink = gst_element_factory_make ("fakesink", "sink");
  bin = gst_bin_new ("mybin");
  gst_bin_add (GST_BIN (bin), sink);

  /* add ghostpad */
  pad = gst_element_get_static_pad (sink, "sink");
  gst_element_add_pad (bin, gst_ghost_pad_new ("sink", pad));
  gst_object_unref (GST_OBJECT (pad));
 }
