PHP FFMPEG not working
<p><a href="https://github.com/PHP-FFMpeg/PHP-FFMpeg" rel="nofollow">https://github.com/PHP-FFMpeg/PHP-FFMpeg</a></p>

<p>I got this from GitHub, and I included the code (at least I thought I did).</p>

<p><code>
require_once '/FFMpeg/FFProbe.php';
require_once '/FFMpeg/FFMpeg.php';
</code></p>

<p>And the code returns with this weird error that I cannot seem to find a solution to on their GitHub Repo page.</p>

<p><code>Fatal error: Class 'Doctrine\Common\Cache\ArrayCache' not found in /FFMpeg/FFProbe.php on line 204</code></p>

<p>Any reason why this error occurs or am I stupid?</p>

<p><strong>EDIT #1:</strong>
It occurs when I use this code that they supplied on their GitHub
<code>
    $ffmpeg = FFMpeg\FFMpeg::create();
    $video = $ffmpeg-&gt;open('video.mpg');
    $video
    -&gt;filters()
    -&gt;resize(new FFMpeg\Coordinate\Dimension(320, 240))
    -&gt;synchronize();
    $video
    -&gt;frame(FFMpeg\Coordinate\TimeCode::fromSeconds(10))
    -&gt;save('frame.jpg');
    $video
    -&gt;save(new FFMpeg\Format\Video\X264(), 'export-x264.mp4')
    -&gt;save(new FFMpeg\Format\Video\WMV(), 'export-wmv.wmv')
    -&gt;save(new FFMpeg\Format\Video\WebM(), 'export-webm.webm');</code></p>
