I got some errors containing: '<b>Notice</b>: Undefined index: resolution in <b>C:\wamp\www\restream\index.php</b> on line <b>.
The problem is that PHP is setup to show also notices. There notices are harmless and it is advised to disable the notice reporting.
You can change this by editing the php.ini file and change the setting 'error_reporting' from 'E_ALL' to 'E_ALL & ~E_NOTICE'
Restart apache and the notices are gone and the software is working.
