TagList.copy

Creates a new #GstTagList as a copy of the old taglist. The new taglist will have a refcount of 1, owned by the caller, and will be writable as a result.

Note that this function is the semantic equivalent of a gst_tag_list_ref() followed by a gst_tag_list_make_writable(). If you only want to hold on to a reference to the data, you should use gst_tag_list_ref().

When you are finished with the taglist, call gst_tag_list_unref() on it.
