Message.parseTag

void parseTag(out gst.tag_list.TagList tagList)

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;
   }
   ...
 }
 ...

MT safe.

Parameters

tagList return location for the tag-list.
