+ * @source: a media source
+ * @uri: A URI that can be used to identify a media resource
+ * @keys: A list of keys to resolve
+ * @flags: the resolution mode
+ * @error: a #GError, or @NULL
+ *
+ * Creates an instance of #GrlMedia representing the media resource
+ * exposed at @uri.
+ * 
+ * It is recommended to call grl_media_source_test_media_from_uri() before
+ * invoking this to check whether the target source can theoretically do the
+ * resolution.
+ *
+ * This method is synchronous.
