BaseParse.mergeTags

void mergeTags(gst.tag_list.TagList tags, gst.types.TagMergeMode mode)

Sets the parser subclass's tags and how they should be merged with any upstream stream tags. This will override any tags previously-set with [gstbase.base_parse.BaseParse.mergeTags].

Note that this is provided for convenience, and the subclass is not required to use this and can still do tag handling on its own.

Parameters

`tags`	a #GstTagList to merge, or NULL to unset previously-set tags
`mode`	the #GstTagMergeMode to use, usually #GST_TAG_MERGE_REPLACE
