title: "Invalid data found when processing input" no matter the FFMPEG configuration
body: <p>I've been stumped on this for a while now, no matter the configuration if use in NodeJS I always get the same error "Error: ffmpeg exited with code 1".</p>
  
  <p>Here's my code:</p>
  
  <pre><code>var http = require('http');
  var fs = require('fs');
  var ffmpeg = require('fluent-ffmpeg');
  
  var server = http.createServer(function(req, res) {
  
      var seektime = 100;
      var pathToMovie = __dirname + '/src/video.mp4';
      var stat = fs.statSync(pathToMovie);
      res.writeHead(200, {
          'Content-Type': 'video/mp4',
          'Content-Length': stat.size
      });
  
      var proc = new ffmpeg(pathToMovie)
      .seekInput(seektime)
      .withVideoBitrate(1024)
      .withVideoCodec('libx264')
      .withAspect('16:9')
      .withFps(24)
      .toFormat('mp4');
  
      var ffstream = proc.pipe(res, {end:true});
      ffstream.on('data', function(chunk) {
          console.log('ffmpeg just wrote ' + chunk.length + ' bytes');
      });
  
  });
  server.listen(8000);
  </code></pre>
  
  <p>I have no idea what to do now. Any ideas?</p>
  
  <p>Thanks,
  Jamie</p>
