PHP module installed but does not appear in phpinfo()

Im tying to install php5-ffmpeg module on my ubuntu server. I've typed:

sudo apt-get install php5-ffmpeg

Everything was installed and web server was reloaded. Now, the fallowing line is added to Additional .ini files parsed in phpinfo(): /etc/php5/apache2/conf.d/ffmpeg.ini

However, no more info about ffmpeg module is not present in phpinfo() and ffmpeg functions do not work in scripts. Here's ffmpeg.ini file contents:

; configuration for the ffmpeg-php module

extension=ffmpeg.so

; Turn ffmpeg warnings into PHP warnings
;ffmpeg.show_warnings=0

; Persistent movies
;ffmpeg.allow_persistent=0

Apache error log shows:

PHP Warning:  PHP Startup: Unable to load dynamic library '/usr/lib/php5/20090626+lfs/ffmpeg.so' - /usr/lib/php5/20090626+lfs/ffmpeg.so: cannot open shared object file: No such file or directory in Unknown on line 0

It is said there PHP Extension: 20090626

I have two directories in /usr/lib/php5:

20060613+lfs/
    ffmpeg.so
20090626+lfs/
    curl.so    gd.so      mysql.so      pdo.so
    mysqli.so  pdo_mysql.so  suhosin.so

I've tried copying ffmpeg.so to 20090626+lfs directory, but in this case Apache error log shows:

PHP Warning:  PHP Startup: ffmpeg: Unable to initialize module\nModule compiled with module API=20060613\nPHP    compiled with module API=20090626\nThese options need to match\n in Unknown on line 0
PHP Warning:  PHP Startup: ffmpeg: Unable to initialize module\nModule compiled with module API=20060613\nPHP    compiled with module API=20090626\nThese options need to match\n in Unknown on line 0

Any ideas why PHP ffmpeg module does not work in this case?

Ubuntu server 9.04, PHP 5.3.1-4, Apache 2
