Synopsis

#include <gst/tag/tag.h>

GstTagList *             gst_tag_list_from_xmp_buffer   (const GstBuffer *buffer);
GstBuffer *              gst_tag_list_to_xmp_buffer     (const GstTagList *list,
                                                         gboolean read_only);

Description

Contains various utility functions for plugins to parse or create xmp packets and map them to and from GstTagLists.

Please note that the xmp parser is very lightweight and not strict at all.
