Codecs locations in filesysten

[Nathaniel Homier <nate.homier@gmail.com>]

Hi, I am trying to install the mplayer codecs all package and the readme 
says to install them to these locations.  However I can not find these 
directories on my system.  I have 3.1r0 with the desktop package.  Does 
Debian create these directories by default or do I have to create them 
myself then put the codec files in them.  I already know how to install 
the codecs I just can't find the directories.  On other distros that 
I've used in the past I could find them.  So should I create the 
directories myself?

/usr/local/lib/codecs/
/usr/lib/codecs
/usr/local/lib/win32
/usr/lib/win32
