The vorbistag element was added in the latest gst-plugins-base release,
0.10.11.

The element is primarily meant to re-tag existing Ogg/Vorbis files
without re-encoding though.

If you want to set tags at the same time as encoding an Ogg/Vorbis file,
you can just set them on the vorbisenc element directly using the
GstTagSetter interface, which vorbisenc implements.

For example, you can do something like:

  GDate *date;

  date = g_date_new_dmy (15, 10, 2006);
  gst_tag_setter_add_tags (GST_TAG_SETTER (vorbisenc),
      GST_TAG_MERGE_APPEND,
      GST_TAG_TITLE, "A Song About Love",
      GST_TAG_ARTIST, "T. Singer & The Unbreakables",
      GST_TAG_ALBUM, "A Whole Album With Songs About Love",
      GST_TAG_COMMENT, "How awesome is this!!!!",
      GST_TAG_DATE, date,
      GST_TAG_TRACK_NUMBER, 1,
      GST_TAG_TRACK_COUNT, 10,
      NULL);
  g_date_free (date);

where vorbisenc is a GstElement from your pipeline.

Hope this helps.

Cheers
