46 * already in the element and (B) the ones that are supplied to the element (
47 * e.g. via gst_tag_setter_merge_tags() / gst_tag_setter_add_tags() or a
48 * %GST_EVENT_TAG), how are these tags merged?
49 * In the table below this is shown for the cases that a tag exists in the list
50 * (A) or does not exists (!A) and combinations thereof.
