TagMergeMode


Description:

[ CCode ( cprefix = "GST_TAG_MERGE_" , type_id = "gst_tag_merge_mode_get_type ()" ) ]
public enum TagMergeMode

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 merge_tags / add_tags or a 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.

| merge mode | A + B | A + !B | !A + B | !A + !B | | ----------- | ----- | ------ | ------ | ------- | | REPLACE_ALL | B | ø | B | ø | | REPLACE | B | A | B | ø | | APPEND | A, B | A | B | ø | | PREPEND | B, A | A | B | ø | | KEEP | A | A | B | ø | | KEEP_ALL | A | A | ø | ø |
