I followed the instructions on http://www.mysql-apache-php.com/ffmpeg-install.htm but ffmpeg-php does not show up in my phpinfo()

The commands I ran (in order)

#yum install ffmpeg ffmpeg-devel
...

#nano /usr/local/lib/php.ini

In which I put these two lines at the end of the php.ini file

[ffmpeg]
extension=ffmpeg.so

Then,

#service httpd restart

But phpinfo() still does not show any 'ffmpeg' section.

This is the correct php.ini because:

#php -i | grep php\.ini
