I got a problem with my php settings, I know that for sure 'cause the exact same lib works perfectly for my partner at HIS server.
$inc_path = get_include_path();
$inc_path .= PATH_SEPARATOR . "./rtmp" . PATH_SEPARATOR . "./SabreAMF";
set_include_path($inc_path);
require_once 'rtmp/SabreAMF/OutputStream.php';
require_once 'rtmp/SabreAMF/InputStream.php';
require_once 'rtmp/SabreAMF/AMF0/Serializer.php';
require_once 'rtmp/SabreAMF/AMF0/Deserializer.php';
require_once 'rtmp/SabreAMF/TypedObject.php';
and this is what I get
Warning: require_once(rtmp/SabreAMF/OutputStream.php): failed to open stream: No such file or directory in C:\Program Files (x86)\EasyPHP-12.1\www\phpLoL-master\rtmp\RtmpClient.php on line 7
