28 * @title: GstUriHandler
29 * @short_description: Interface to ease URI handling in plugins.
31 * The #GstURIHandler is an interface that is implemented by Source and Sink
32 * #GstElement to unify handling of URI.
34 * An application can use the following functions to quickly get an element
35 * that handles the given URI for reading or writing
36 * (gst_element_make_from_uri()).
38 * Source and Sink plugins should implement this interface when possible.
