I know that he is searching in the root directory.
but how to change that?

here is my config.php
$config = array();
$config['ffmpeg'] = "/usr/local/bin/ffmpeg";
$config['mplayer'] = "/usr/local/bin/mplayer";
$config['mencoder'] = "/usr/local/bin/mencoder";
$config['flvtool'] = "/usr/bin/flvtool2";
$config['basedir'] = "/var/www/web0/html";
$config['baseurl'] = "http://speedriding-videos.com";

include($config['basedir'] . "/include/vshare.php");
