Starting from beginning:

apt-get remove libopenh323* gnomemeeting libpwl ffmpeg

None of them are now on my machine.

From the website:

The FFMPEG library

To use H.263 with OpenH323, it is necessary to have compiled version of 
the ffmpeg library for your platform. It is recommended that you use of 
the precompiled libraries for Windows or Linux unless you have some 
specific need to alter the ffmpeg sources yourself

For Linux, download header files and a recompiled library
For Windows, download header files and a recompiled library

What does this mean? I need a compiled ffmpeg - does this mean I need a 
patched ffmpeg?

What is the next step? For linux download header files and a recomplied 
library - this isn't a ffmpeg binary though. It contains 3 files:

common.h
avcodec.h
libavcodec.so

Since it states I need a compiled ffmpeg what can I do about that? Or do 
I just go ahead and compile OpenH323 without ffmpeg?
