gst_element_get_pad requests a pad by name, but the videoscale element
does not have any pad named "padVideoScale". The available pads are
named "src" and "sink". This might explain why your callback function
is never called.

By the way, gst_element_get_pad is deprecated (see
http://www.freedesktop.org/software/gstreamer-sdk/data/docs/2012.5/gstreamer-0.10/GstElement.html#gst-element-get-pad).
