Warning: file_exists(): open_basedir restriction in effect. File(/usr/bin/ffprobe) is not within the allowed path(s): (D:/inetpub/wwwroot/wiki/) etc...
1.) there is no /usr/bin on windows.
2.) sketchy ffprobe windows binaries not listed as requirement for this extension.
3.) configuration instructions incomplete. Where does one set up the configuration options?
Please rewrite the extension so that it doesn't require ffprobe.
