Yep, read all the notes I can find on the site, forums, Wiki and doco.
Problem relates to configure generation:
II can't find my libavformat.a & libavcodec.a even though they are cached (ldconfig -v | grep libav proves it is seen by the system). I have installed ffmpeg-0.4.9.9152-6.2.
I have placed the libraries in /usr/local/lib and additionally into /lib. But no joy

Neither library is seen by the configuration process.
I tried using the extralibs directive but no go, same issue.
What to do ?
Thanks Grahame.
