pass d3dvideosink a window id

[jacob s]

I forgot to name the d3dvideosink.
fixed to:
pipeline = gst_parse_launch ("videotestsrc ! videoconvert ! d3dvideosink
name=thed3dvideosink",NULL);
d3dvideosink_element =
gst_bin_get_by_name((GstBin*)pipeline,"thed3dvideosink");

now it doesn't show a window at all ( also no error reported )
