external command not executing in exec/system function
<p>I am using ffmpeg to convert my mp3, but I don't get any output returned back from exec/system function:</p>

<pre><code> exec($command, $ffmpegOutput);
</code></pre>

<p>My $ffmpegOutput variable is empty after execution. If I do something like:</p>

<pre><code> exec('dir', $DirOutput);
</code></pre>

<p>It works. So my guess was that php can't find ffmpeg executable. But if I type the same command in command prompt it works all well. I have configured ffmpeg bin folder in my PATH as well as CLASSPATH. What am I missing? I am running Windows 7.</p>
