title: FFmpeg and qt, Unable to find a suitable output format for '>'
body: <p>I'm trying to execute a ffmpeg operation through Qt</p>
  
  <p>I would like to execute this line :</p>
  
  <pre><code>./ffmpeg -t 10 -i temp1 -f mpeg  -  &gt;  temp2
  </code></pre>
  
  <p>When I execute through the terminal, it works perfectly fine.</p>
  
  <p>How ever when I launch it through Qt like this :</p>
  
  <pre><code> QProcess    *process = new QProcess();
  
   QString parameters("./ffmpeg -t 10 -i temp1 -f mpeg  - &gt;  temp2");
   std::cout &lt;&lt; process-&gt;execute(parameters) &lt;&lt; std::endl;
  </code></pre>
  
  <p>I get an <code>Unable to find a suitable output format for '&gt;'</code> any body has the idea of why ?</p>
