Function

Gst-1.0 ▶ Gst ▶ tag_list_replaceSince 1.16

  • Modifies a pointer to a Gst.TagList to point to a different Gst.TagList. The modification is done atomically (so this is useful for ensuring thread safety in some cases), and the reference counts are updated appropriately (the old tag list is unreffed, the new is reffed).

    Either new_taglist or the Gst.TagList pointed to by old_taglist may be null.

    Parameters

    • old_taglist: TagList | null

      pointer to a pointer to a Gst.TagList to be replaced.

    • new_taglist: TagList | null

      pointer to a Gst.TagList that will replace the tag list pointed to by old_taglist.

    Returns [boolean, TagList | null]

    true if new_taglist was different from old_taglist
