I do not understand where you get that from.
I have different versions on the machine, but I have given the path to
the latest version in the script.

Thank you for this info.
I have pasted the output below.

That is what I think I have done but you may see a fault that I do not see.

I have put my compilation below and the other info also below.
I very much appreciate you help with this, since it is troubling me
for a long time.

This is my .bash_histry file

cat readme.txt
cd ffmpeg
PKG_CONFIG_PATH="$HOME/ffmpeg_build/lib/pkgconfig" ./configure
--prefix="$HOME/ffmpeg_build"
--extra-cflags="-I$HOME/ffmpeg_build/include"
--extra-ldflags="-L$HOME/ffmpeg_build/lib -ldl" --bindir="$HOME/bin"
--pkg-config-flags="--static" --enable-gpl --enable-nonfree
--enable-libfdk_aac --enable-libfreetype --enable-libmp3lame
--enable-libvorbis --enable-libvpx --enable-libx264
make
make install

To my understanding I have done it correct.
But you may find some error in it.

[root at spancro /]# which x264
