[FFmpeg-devel] NellyMoser transform bug

While looking at the NellyMoser audio decoder, I found a very suspect 
code which makes the transform incorrect in the sense that there is 
information loss. So I suggest the attached patch.

Can someone confirm that my code corresponds to what the "reference" 
decoder does ? If it does, then I confirm that it is possible to convert 
the code to use the ffmpeg IMDCT code...
