 Summary of the suggestion:

 libx264 new versions sometimes use --enable-opencl config option by
 default, so you should state in the guide that the libx264 configure
 command line should contain the --disable-opencl tag, otherwise
 if you compile ffmpeg without --enable--opencl (because you did not
 install it) but with --enable-libx264, ffmpeg configure command will fail
 with "ERROR: libx264 not found"

 How to reproduce:

 visit https://trac.ffmpeg.org/wiki/CompilationGuide/Centos and execute
 steps to install ffmpeg on Centos.
