VU Meter in custom UI

[peppy.player]

Hi,

I use VLC and Python binding with my own custom UI written in Python with Pygame library.
There is VU meter screensaver which works fine with MPD player:
https://github.com/project-owner/PeppyMeter.doc/wiki
but I'm not sure how to make it working with VLC. It can read PCM signal from named pipe.
In case of MPD you can ask player to output to the additional channel (e.g. named pipe). Is it
possible to accomplish the sane with VLC so that in addition to alsa sound card output it could
also output to a named pipe?

Thanks in advance!
