title: "Unknown encoder: libx264" error in Debian Squeeze
body: <p>I built and installed FFMPEG as <a href="http://www.zoharbabin.com/build-and-install-ffmpeg-and-x264-on-debian-squeeze-the-dumb-guide" rel="nofollow">said here</a>.</p>
  
  <p>But when I do this command to run the video:</p>
  
  <pre><code>ffmpeg -i "source.mkv" -an -b 700k -r 25 -vcodec libx264 "output.mp4"
  </code></pre>
  
  <p>I get this error: </p>
  
  <pre><code>unknow encoder : libx264
  </code></pre>
  
  <p>I use Debian Squeeze. How can I fix this? Please help</p>
  
  <p>Thanks!!</p>
