My blog post talks about doing fades on a GStreamer pipeline for the
generic case. You should still be able to implement your own fades
without too large an effort if you're not trying to build a generic
framework out of it.
If you do want to do a generic thing, we really need the proper
API/infrastructure to implement effects and this is somewhat
