I've tried using the sample code from <A HREF="https://developer.gnome.org/gst-plugins-libs/0.10/gst-plugins-base-libs-gstxoverlay.html">https://developer.gnome.org/gst-plugins-libs/0.10/gst-plugins-base-libs-gstxoverlay.html</A> 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 </BODY> </HTML>
