Element Signals:
"client-draw" : gboolean user_function (GstElement* object,
GstGLContext* arg0,
GstSample* arg1,
gpointer user_data);
"client-reshape" : gboolean user_function (GstElement* object,
GstGLContext* arg0,
guint arg1,
guint arg2,
gpointer user_data);
"create-element" : GstElement * user_function (GstElement* object,
gpointer user_data);
Children:
sink
glcolorbalance0
glcolorconvertelement0
gluploadelement0
I also call gst_init() in the first lines of my application, before all the
gst_element_factory_make. The other elements are correctly created by
gst_element_factory_make, it just fails with glimagesink.
