GstVaapiDecode is a descendant of GstVaapiMiniObject, so, thought we should use its methods, even though it doesn't change functionality. GstVaapiPixmap, GstVaapiTexture and GstVaapiWindow are descendant of GstVaapiObject, hence its methods shall be used. https://bugzilla.gnome.org/show_bug.cgi?id=772554
