Comment 18 for bug 64905

>I would like to learn if/how it is possible to specify a muxer in the pipeline which creates ID3 v2.3 tags but that's a separate issue.

It's possible to build such a pipeline but at first you have to install plugin that's available in Gstreamer's Bugzilla. The bug includes a .tar.gz that provides the source code and build instructions of the plugin.
