According to :
http://svn.mplayerhq.hu/ffmpeg/trunk/subdir.mak?view=log
this was changed with revision 12194, whose comment is :
<<<<<<<<<<<<<
Install headers in $prefix/include/$libname

Install each library's headers in $prefix/include/$libname.
The installed headers use #include "lib*/*.h"; applications
are expected to do the same.

Specify only $prefix/include in .pc files.
>>>>>>>>>>>>

Unfortunately, it seems the debian packager decided to use 
/usr/include/ffmpeg/lib*/*h :-/

I don't know what is the best course of action : make opal behave well 
with the package or report it as a packaging bug :-/
