Problem with example code on Ubuntu 12.04

[Marlon Smith]

Hi everyone,

I'm using Ubuntu 12.04 for the Wandboard, and I'm trying to get a Qt
application to play a video with GStreamer.  I've tried using the sample
code from
https://developer.gnome.org/gst-plugins-libs/0.10/gst-plugins-base-libs-gstxoverlay.html but I get the following errors when I run the application:

(gst-plugin-scanner:2890): GStreamer-CRITICAL **: gst_pad_template_new:
assertion `caps != NULL' failed

(gst-plugin-scanner:2890): GStreamer-CRITICAL **:
gst_element_class_add_pad_template: assertion `GST_IS_PAD_TEMPLATE
(templ)' failed

(gst-plugin-scanner:2890): GStreamer-CRITICAL **: gst_pad_template_new:
assertion `caps != NULL' failed

(gst-plugin-scanner:2890): GStreamer-CRITICAL **:
gst_element_class_add_pad_template: assertion `GST_IS_PAD_TEMPLATE
(templ)' failed
MAX resolution 1920x1080

(gsttest:2889): GStreamer-CRITICAL **: gst_element_set_state: assertion
`GST_IS_ELEMENT (element)' failed

(gsttest:2889): GStreamer-CRITICAL **: gst_object_unref: assertion
`((GObject *) object)->ref_count > 0' failed

Does anyone know what could be causing these errors?  I am new to
GStreamer.

Thanks!

Marlon
