/* So some words about GstMiniObject, this is pretty messy...
GstMiniObject does not use the standard finalizing of GObjects, you are
supposed to call gst_buffer_unref that's going to call gst_mini_objec_unref
which will handle its own refcount system and call gst_mini_object_free.
gst_mini_object_free will call the class finalize method which is not the
one from GObject, after calling this finalize method it will free the object
instance for you if the refcount is still 0 so you should not chain up */
