The different tag merging modes are basically replace, overwrite and append,
but they can be seen from two directions. Given two taglists: (A) the tags
already in the element and (B) the ones that are supplied to the element (
e.g. via gst_tag_setter_merge_tags() / gst_tag_setter_add_tags() or a
Gst.EventType.TAG), how are these tags merged?
In the table below this is shown for the cases that a tag exists in the list
(A) or does not exists (!A) and combinations thereof.
