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?

I have got that.
OK let's say that on my system:
I have a ffmpeg on my PC that was gotten from Ubuntu resposities.
That won't work.
Now to compile OpenH323 I can use the precompiled libavcodec:
I did that. I ran the command ./configure
--enable-rfc2190avcodec=[source of avcodec.h that came from the
precompiled libavcodec]
checking libavcodec-0.4.7/avcodec.h usability... no
checking libavcodec-0.4.7/avcodec.h presence... no
checking for libavcodec-0.4.7/avcodec.h... no
configure: Skipping tests for VIC H.263 and non-standard H.263
That is what I get.
Check config.log?
This line puzzles me: checking libavcodec-0.4.7/avcodec.h presence... no
I've checked and double checked and triple checked - it is pointing to
the right location of the libavcodec library that I got from the
website. Yet when I do the configure it will not find avcodec.h.
Given the full path?
Now do I need a patched ffmpeg as well? Or it doesn't matter which
ffmpeg I use?
Yes, use the binary.

Hi,
you can downnload libavcodec from here:
http://www.voxgratia.org/bin/libavcodec-0.4.7-linux.bin.tar.gz and take
a closer look at http://www.voxgratia.org/docs/h263_codec.html ;)
Regards,
Iason
