That's what you'd use if you wanted to add a new branch to the playback
pipeline.  The other alternative is .add_filter(), which inserts an
element into the existing pipeline.  Adding a filter is likely to be
more reliable.

If you want to make those things attributes of your plugin object, that's
the way to do it.

Consult the GStreamer documentation
(http://gstreamer.freedesktop.org/documentation/) for more information
on that.  It's not really relevant that you're using Python here.
GStreamer is GStreamer, whatever language you're using.
