hello,
i'm new to ffmpeg extension i want to install it on my localhost to explore how it works to try to use it on my php scripts
i'm having wampserver 2.2 on windows 7 i've read the instractions some where as stated below:

1. Download ffmpeg-php-5.3-win32-all
2. Copy php_ffmpeg.dll from the php5 folder to the C:\wamp\bin\php\php5.2.9-2\ext
3. Copy the rest of files from to the windows/system32 folder
4. Add
   
   [PHP_ffmpeg] extension=php_ffmpeg.dll to php.ini file
5. Restarted all services (Apache, PHP...)

i made a small code to test the installation
