Error on line 177

I was trying to upload some videos on this video page, I am the web developer for a new installed "vShare YouTube Clone v2.4"
and I recived this error message:

Fatal error: Call to a member function getduration() on a non-object in /home/messiani/public_html/include/functions_upload.php on line 177

Is there something I need to do? I did upload it a video prior to this, and I had not problems. As a matter of a fact it was alot bigger than this one.

Thank you,

ffmpeg-php not properly installed.

To verify ffmpeg-php is working, download

http://www.buyscripts.in/vshare/vshare_test.zip

and upload to your web site and go to url

http://yourdomain/vshare_test/ffmpeg_php_info.php

This is simple PHP script to test ffmpeg-php, if ffmpeg-php is working properly, it will create thumbnail image for the video in the zip.
