+ * This element adds ID3v2 tags to the beginning of a stream using the taglib
+ * library. More precisely, the tags written are ID3 version 2.4.0 tags (which
+ * means in practice that some hardware players or outdated programs might not
+ * be able to read them properly).

+ * Applications can set the tags to write using the #GstTagSetter interface.
+ * Tags sent by upstream elements will be picked up automatically (and merged
+ * according to the merge mode set via the tag setter interface).

+ * Here is a simple pipeline that transcodes a file from Ogg/Vorbis to mp3
+ * format with an ID3v2 that contains the same as the the Ogg/Vorbis file:
