Original commit message from CVS:
2006-05-11  Thomas Vander Stichele  <thomas at apestaart dot org>

patch by: Sjoerd Simons (sjoerd@luon.net)

* gst/playback/gstplaybasebin.c: (gst_play_base_bin_class_init),
(group_create), (group_destroy), (add_stream),
(gst_play_base_bin_get_property),
(gst_play_base_bin_get_streaminfo_value_array):
* gst/playback/gstplaybasebin.h:
API: GstPlayBaseBin::stream-info-value-array property
use a more bindings-friendly way of exposing streaminfo
using a GValueArray.  Tested in ipython.
Closes #341114
