As I understood, there is xmms is needed for using mplayer with
libvisual and its xmms-plugins. If it is true, IMHO it is too
inconvenient for lots of application and bulky.

I think there is another and more powerfull approach could
be used to add this feature to mplayer without xmms and libvisual.
It could be implemented as additional feature which is enabled
in command line (maybe with -viz [oscill | spectrum | ... ]) only
if only one stream is present - audio.

This feature could be useful for various diagnostic / test /
demonstration purposes.

Any advices / objections?

Thank you for your consideration.
