Hi,

There is a visualization *effect* plugin (not output plugin) that must
be put in the effect chain (`xmms2 server config effect.order.<N>
visualization` where <N> is the position of the plugin in the chain (0
if there is no other effect)).

Then, data is retrieved client side. There are 3 types of data you can
get from the visualization plugin: raw pcm data, fft data (spectrum) and
peak data. There are visualization clients examples in
src/clients/vistest/ in xmms2's source tree.

Beyond the visualization plugin that provides the data, visualization
has nothing to do with xmms2d: It's a client stuff. Which means that if
you want old xmms plugins to be usable with xmms2, you'll need to write
a client that knows how to use them (probably without major changes
though, if you want them to use recent graphic frameworks): but note
that they will be part of your client, not directly xmms2's.
