Comment:

 FFmpeg can directly access the libx264 presets instead of emulating them
 with a text file (these files have been removed), so in most cases you
 should be using -preset instead of -vpre. To modify any options the preset
 sets, or to add additional options, you can use -x264opts such as:

 {{{
 ffmpeg -i input -vcodec libx264 -preset medium -x264opts weightp=1
 -threads 0 output
 }}}

 Unrelated side note: --enable-pthreads --enable-bzlib --enable-zlib are
 detected automatically, so you don't need these in your configure.
