Iason Antipariotis gave you a link to the a .tar.gz that contains both
the recompiled library and the header files.

I do :
mkdir /home/damien/CVS/LIBAVCODEC
tar xvzf of the library in LIBAVCODEC
I go in /home/damien/CVS/openh323
and I type :
./configure --enable-rfc2190avcodec=/home/damien/CVS/LIBAVCODEC/

And I get :

checking /home/damien/CVS/LIBAVCODEC//avcodec.h usability... yes
checking /home/damien/CVS/LIBAVCODEC//avcodec.h presence... yes
checking for /home/damien/CVS/LIBAVCODEC//avcodec.h... yes


It works... I don't understand your problem.
