Is there any way to set/get multiple audio-sink and video-sink in playbin?

[HoonHee Lee]

I want to set multiple audio-sink and video-sink using below code in playbin
on Gst-v1.0.
=> g_object_set (playbin, "audio-sink", "fakesink|fakesink", NULL);

When I used gst-launch-1.0 audio-sink="fakesink|fakesink", It was possible.
Because when I tried to use g_value_object_get (object) in get_property func
in playbin,
this object had one pipeline(bin) that contains 2 fakesink elements.

But, I think that gst-launch and g_object_set is different with processing
logic.
Thus, I Implemented new element such as gstplaysinkcontainer in my local
that contains video and audio sink reference in array type.

Below is an example code.
--------------------------------------------------------------------------------------------
  GstElement *container;
  GstElement *fakesink1, *fakesink2;
  GValue v1 = { 0, };
  GValue v2 = { 0, };
  GValueArray *va;
  GValueArray *result;

  container = gst_element_factory_make ("playsinkcontainer", NULL);
  fakesink1 = gst_element_factory_make ("fakesink", NULL);
  fakesink2 = gst_element_factory_make ("fakesink", NULL);

  va = g_value_array_new (2);

  g_value_init (&v1, GST_TYPE_ELEMENT);
  g_value_set_object (&v1, fakesink1);
  g_value_array_append (va, &v1);
  g_value_unset (&v1);

  g_value_init (&v2, GST_TYPE_ELEMENT);
  g_value_set_object (&v2, fakesink2);
  g_value_array_append (va, &v2);
  g_value_unset (&v2);

  g_object_set (G_OBJECT (container), "video-sinks", va, NULL);

  g_object_set (playbin, "video-sink", container, NULL);
---------------------------------------------------------------------------------------

IMHO, above approach works fine.
But, What I want to do is that get the best approach for that.

Could you tell me that how can I set/get multiple audio and video sink using
"audio/video-sink" properties?
