You seem to have local hack, since xvimagesink is primary rank, while
cluttersink is marginal. cluttersink shouldn't be picked by
autovideosink in un-modified builds. It also does not support being
embedded into X11 application, so it's ill advise to rank it higher
then marginal.

You can always edit the ranks inside your application. Use GstRegistry
to find the GstPluginFeature, and modify it
(gst_plugin_feature_set_rank()).
