listening for tags on audio stream

["W. de Hoog" <wdehoog exalondelft nl>]

Hi,

As tipped on this list (in may) I am listening to tag signal on the playbin.

In rygel-playbin-renderer.vala:

        case MessageType.TAG:
            Gst.TagList tag_list;
            debug ("taglist found\n");
            message.parse_tag (out tag_list);
            tag_list.foreach ((TagForeachFunc) foreach_tag);
            break;
and:
    private void foreach_tag (Gst.TagList list, string tag) {
        switch (tag) {
        case "title":
            string tag_string;
            list.get_string (tag, out tag_string);
            debug ("tag: %s = %s\n", tag, tag_string);
            break;
        default:
            debug ("unknown tag: %s\n", tag);
            break;
        }
    }

all copied from https://wiki.gnome.org/Projects/Vala/GStreamerSample

But I never get a usefull tag. This is printed in the log:

  (rygel:24680): RygelRendererGst-DEBUG: rygel-playbin-player.vala:580:
  taglist found
  (rygel:24680): RygelRendererGst-DEBUG: rygel-playbin-player.vala:520:
  unknown tag: \x80\xe8\xf9
  (rygel:24680): RygelRendererGst-DEBUG: rygel-playbin-player.vala:520:
  unknown tag: \x80\xe8\xf9

Always this 'unknown tag: \x80\xe8\xf9'

Any ideas on what is going wrong?
