There is some error, you need to turn on error reporting in php configuration.

Also make sure all requirements are properly installed on your server

http://www.vshare.in/requirements.html

I can't see ffmpeg-php listed on your phpinfo. So other requirements may be missing.

If your web host do not support requirements, check http://www.hostonnet.com/ffmpeg_hosting.php for web hosting with all requirements of vshare.
