mpeglib is not meant to be used by qt application. Better use
artsd for this job.

A note about the artsd conversion:

artsd does a int->float conversion because its internally works
with ints. A volume changer works on the floats (scales them)
later they are converted to int again.

In other words: The wav file you will get (may) has nothing to do
                with the real wav file, which would be written
                by a direct mp3/ogg -> wav writer.(remeber this!)

Currently there is no official codec API for KDE.
(Something like acm,vfw under windos)

Maybe we should define such an API.

Martin
