Wenn ich versuche, etwas hochzuladen, wird folgende Fehlermeldung angezeigt:

Error code:1363030,
msg: Your video upload timed out before it could be completed. This is probably because of a slow network connection or because the video you're trying to upload is too large. Please try again.

Ich verwende Facebook Javascript SDK 2.5. Was fehle ich oder falsch?

<script>
      var files;
      var fileData = '';  
      function handleFileSelect(evt) {
        files = ,evt.target.files; // FileList object
        var input = evt.target;
        var reader = new FileReader();
        reader.onload = function (e) {
          fileData = e.target.result;
        };
        reader.readAsDataURL(input.files[0]);
        // files is a FileList of File objects. List some properties.
        var output = [];
        for (var i = 0, f; f = files[i]; i++) {
          output.push('<li class="list-group-item">', escape(f.name), '(', f.type || 'n/a', ') - ',
                      f.size, ' bytes','</li>');
        }
        document.getElementById('list').innerHTML = output.join('');
      }
      document.getElementById('files').addEventListener('change', handleFileSelect, false);

      $(document).ready(function()
      {

        $("#upload").click(function(){
          var token = $('#token').val();
          FB.api(
            "/me/videos",
            "POST",
