How to change rank of a plugin by configuration(without change code and recompile)

[Julien Moutte]

Here is how it's done in Moovida :

bp_enable_factory (const gchar *name, gboolean enable)
{
    GstRegistry *registry = NULL;
    GstElementFactory *factory = NULL;

    registry = gst_registry_get_default ();
    if (G_UNLIKELY (!registry)) {
        bp_debug ("failed retrieving default registry");
        goto beach;
    }

    factory = gst_element_factory_find (name);
    if (G_UNLIKELY (!factory)) {
        bp_debug ("unable to locate the %s factory", name);
        goto beach;
    }

    // Raise Rank to Primary + 2 as Fluendo codecs use Primary + 1.
    if (enable) {
        gst_plugin_feature_set_rank (GST_PLUGIN_FEATURE (factory),
GST_RANK_PRIMARY + 2);
    }
    else { // Or set it back to NONE.
        gst_plugin_feature_set_rank (GST_PLUGIN_FEATURE (factory),
GST_RANK_NONE);
    }

beach:
    if (factory && registry) {
        gst_registry_add_feature (registry, GST_PLUGIN_FEATURE (factory));
    }

    return;
}
