Try either ffmpeg or libav-tools.  Either ffmpeg or avconv can do this.  I 
don't know the specific command because I don't use them for that purpose, 
but I'm sure there is a normalization filter.  If you transcode the video to 
audio (they can do that too) there is also sox which works well.  I offer a 
$99 per year support service for these kinds of questions.  Please see my 
contact information in my signature.
