title: Fail to set profile to high when using ffmpeg with libx264
body: <p>Here is my command:</p>
  
  <pre><code>ffmpeg -i input.avi -vcodec libx264 -vpre fast -vpre high -acodec copy output.avi
  </code></pre>
  
  <p>The output:</p>
  
  <pre><code>Input #0, avi, from 'short.avi':

  File for preset 'high' not found
  </code></pre>
  
  <p>However, I am able to successfully transcode files when setting the profile to baseline or main, from the man page of x264 it is clear that "high" should also be a valid argument. I also want to know where these preset files are located in the file system(I am running ubuntu 11.10) so that I can make sure what arguments I can actually use for presets and profiles at the moment. I am very frustrated by this issue and would really appreciate any input from you guys. Thanks in advance.</p>
