  <p>I want to use libx264 codec with ffmpeg.
  when i tried to convert image files to a video using the codec, a message appears said Unknown encoder "libx264". so I tried to execute configure and make again at msys folder. I typed ./configure --enable-libx264 and it failed. :(</p>
  
  <p>my ffmpeg version is 3.0.1 and x264 is also the latest version so far.</p>
