* Applications can set the tags to write using the #GstTagSetter interface.

* Here is a simple pipeline that transcodes a file from Ogg/Vorbis to mp3
|

|
* format with an APEv2 that contains the same as the the Ogg/Vorbis file:
|
||
|
* <programlisting>
|
||
|
* gst-launch -v filesrc location=foo.ogg ! decodebin ! audioconvert ! lame ! apev2mux ! filesink location=foo.mp3
|
||
|
* </programlisting>
|
||
|
* Make sure the Ogg/Vorbis file actually has comments to preserve.
|
||
|
* You can verify the tags were written using:
|
||
|
* <programlisting>
|
||
|
* gst-launch -m filesrc location=foo.mp3 ! apedemux ! fakesink silent=TRUE 2> /dev/null | grep taglist
|
