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;
}
...
}
...
