Yes and no.

You can change the rank for an element using
gst_plugin_feature_set_rank(), but that affects the entire
application/process then.

You can use decodebin's "autoplug-*" signals to determine on a case-by-
case basis which elements should be picked. So you can sort that based
on your own preferences, or even provide elements that are not ranked.
