title: libvpx: Compiling simple encoder example
body: <p>I am trying to compile Googles libvpx encoder example which can be found here:</p>
  
  <p><a href="http://www.webmproject.org/docs/vp8-sdk/example__simple__encoder.html" rel="nofollow">http://www.webmproject.org/docs/vp8-sdk/example__simple__encoder.html</a></p>
  
  <p>Unfortunately libvpx seems to miss dependencies:</p>

  <p>I'm using Fedora 18 x64 and have built libvpx from source (make + make install), so everything should be in place. Anybody else who ran into this problem?</p>
