+ * GstTagMergeMode:
+ * @GST_TAG_MERGE_UNDEFINED: undefined merge mode
+ * @GST_TAG_MERGE_REPLACE_ALL: replace all tags (clear list and append)

+ * @GST_TAG_MERGE_KEEP: keep existing tags

+ * @GST_TAG_MERGE_COUNT: the number of merge modes
+ *
+ * The different tag merging modes are basically replace, overwrite and append,

+ * 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_EVENT_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.
