title: Install ffmpeg on elastic beanstalk using ebextensions config
body: <p>I'm attempting to install an up to date version of ffmpeg on an elastic beanstalk instance on amazon servers. I've created my config file and added these container_commands:</p>
  
  <pre><code>    container_commands:
          01-ffmpeg:
              command: wget -O/usr/local/bin/ffmpeg http://ffmpeg.gusari.org/static/64bit/ffmpeg.static.64bit.2014-03-05.tar.gz
              leader_only: false
          02-ffmpeg:
              command: tar -xzf /usr/local/bin/ffmpeg
              leader_only: false
          03-ffmpeg:
              command: ln -s /usr/local/bin/ffmpeg /usr/bin/ffmpeg
              leader_only: false
  </code></pre>
  
  <p>Command 01 and 03 seems to work perfectly but 02 doesn't seem to work so ffmpeg doesn't unzip. Any ideas what the issue might be?</p>
  
  <p>Thanks,
  Helen</p>
