Yes. g_object_set() expects an integer for an enum property, not a
GValue structure.

   g_object_set_property(G_OBJECT (decoder), "compliance", &value);

might work for a GValue though.

This should also work:

 gst_util_set_object_arg( G_OBJECT( decoder ), "compliance",
"flexible" );

Or this:

 g_object_set (decoder, "compliance", 3, NULL);
