24 * SECTION:element-id3mux
25 * @see_also: #GstID3Demux, #GstTagSetter
27 * This element adds ID3v2 tags to the beginning of a stream, and ID3v1 tags
30 * It defaults to writing ID3 version 2.3.0 tags (since those are the most
31 * widely supported), but can optionally write version 2.4.0 tags.
33 * Applications can set the tags to write using the #GstTagSetter interface.
34 * Tags sent by upstream elements will be picked up automatically (and merged
35 * according to the merge mode set via the tag setter interface).

41 * ]| A pipeline that transcodes a file from Ogg/Vorbis to mp3 format with
