title: Laravel FFMPEG Error Encoding Failed using Laravel Queue
body: <p>I am using <code>"php-ffmpeg/php-ffmpeg": "~0.5"</code> with Laravel 5. I am using this library for compression and conversion of recorded videos. I will explain the scenario first.</p>
  
  <p>When I execute following code from controller it works like charm.</p>
  
  <pre><code>$ffmpeg = FFMpeg::create();
  $video = $ffmpeg-&gt;open(public_path()."/videos/harsh.webm");
  $video
      -&gt;filters()
      -&gt;resize(new \FFMpeg\Coordinate\Dimension(640, 480))
      -&gt;synchronize();
  $video
      -&gt;frame(\FFMpeg\Coordinate\TimeCode::fromSeconds(10))
      -&gt;save(public_path().'/videos/converted/kaushik.jpg');
  $format=new \FFMpeg\Format\Video\X264('libmp3lame', 'libx264'); 
  $format-&gt; setKiloBitrate(300);
  $video-&gt;save($format,public_path().'videos/converted/kaushik.mp4');``
  </code></pre>
  
  <p>But when I put this code in a queue job then it fails with following error</p>
  
  <blockquote>

  <p>I am able to convert video in MWV and WEBM using following</p>
  
  <pre><code>$video-&gt;save(new \FFMpeg\Format\Video\WMV(), 'export-wmv.wmv');
  $video-&gt;save(new \FFMpeg\Format\Video\WebM(), 'export-webm.webm');
  </code></pre>
  
  <p>only mp4 fails if I use the </p>
  
  <pre><code>$format=new \FFMpeg\Format\Video\X264('libmp3lame', 'libx264');
  </code></pre>
