Jukebox once provided random graphical visualisations when playing an audio track.

Feature was provided by the GStreamer library.

We turned it off because it wasn't working properly. It either didn't appear, appeared in the wrong place, or appeared after playing.

See if you can make it work properly.

You may need to work with the GStreamer project and their source code to find out what is needed. You might also look at other software that uses the GStreamer visualisation feature so you can find out the correct sequence of code.
