/**
 * Element interface that allows setting of media metadata.
 *
 * Elements that support changing a stream's metadata will implement this
 * interface. Examples of such elements are 'vorbisenc', 'theoraenc' and
 * 'id3v2mux'.
 *
 * If you just want to retrieve metadata in your application then all you
 * need to do is watch for tag messages on your pipeline's bus. This
 * interface is only for setting metadata, not for extracting it. To set tags
 * from the application, find tagsetter elements and set tags using e.g.
 * gst_tag_setter_merge_tags() or gst_tag_setter_add_tags(). Also consider
 * setting the GstTagMergeMode that is used for tag events that arrive at the
 * tagsetter element (default mode is to keep existing tags).
 * The application should do that before the element goes to GST_STATE_PAUSED.
 *
 * Elements implementing the GstTagSetter interface often have to merge
 * any tags received from upstream and the tags set by the application via
 * the interface. This can be done like this:
 *
 * $(DDOC_COMMENT example)
