$(…).vidbg is not a function

I just resolved this by replacing the $ with jQuery on line 213:

<?php if( isset( $container_field ) ): ?>
      <script type="text/javascript">
        jQuery(function($){
213            jQuery('<?php echo $container_field; ?>').vidbg({
                  'mp4': '<?php echo $mp4_field; ?>',
                  'webm': '<?php echo $webm_field; ?>',
                  'poster': '<?php echo $poster_field; ?>',
              }, {
                // Options
                muted: <?php if($unmute_field == 'on'): ?>false<?php else: ?>true<?php endif; ?>,
                loop: <?php if($no_loop_field == 'on'): ?>false<?php else: ?>true<?php endif; ?>,
								overlay: <?php if($pattern_overlay == 'on'): ?>true<?php else: ?>false<?php endif; ?>,
              });
          });
      </script>
    <?php endif; ?>
