Message.parseTag

Extracts the tag list from the GstMessage. The tag list returned in the output argument is a copy; the caller must free it when done.

Typical usage of this function might be:

...
switch (GST_MESSAGE_TYPE (msg)) {
  case GST_MESSAGE_TAG: {
    GstTagList *tags = NULL;

    gst_message_parse_tag (msg, &tags);
    g_print ("Got tags from element %s\n", GST_OBJECT_NAME (msg->src));
    handle_tags (tags);
    gst_tag_list_unref (tags);
    break;
  }
  ...
}
...
