title: Compilation error when compiling libvpx for FFMPEG
body: <p>I'm compiling FFMPEG on my 64bit Ubuntu 14 machine. Everything compiled well, except for the libvpx library, which keeps throwing errors:</p>
  
  <pre><code>[AS] vp9/common/x86/vp9_subpixel_8t_ssse3.asm.o

  <p>I followed this guide: <a href="https://trac.ffmpeg.org/wiki/CompilationGuide/Ubuntu" rel="nofollow">https://trac.ffmpeg.org/wiki/CompilationGuide/Ubuntu</a>
  I don't know what this error means, but read somewhere that compiling libvpx with NASM is broken, but I don't know how to compile it otherwise. Installing version 1.2 or 1.1 makes no difference whatsoever. Any ideas?</p>
