How to create .avi and mpeg video thumbnail?

Hi all. i got a huge list of video(.avi and mepeg) in my pc. I want to create a php script that displays all the video names along with its thamnail.(I already have video name and path in mysql db).

After searching google i came to this program called ffmpeg and i tried to install it but it never work.The page takes for ever to load and nothing happens. Could any one help me install it in Apache/1.3.33 (Win32) (wamp server). My main goal is to create thamnail for all these videos and store the location of those thambs in db too. I hope some one help me.Thanks


Installation method that doesn't work:

Download the latest version from:
http://ffdshow.faireal.net/mirror/ffmpeg/

Install:
unzip it to a folder on your computer. that´s all!


This is how I use ffmpeg and PHP


<?php

// movie.avi.... name of the movie you want to take a screenshot from
// 00:00:00.... Where in the movie do you wanna take your screenshot, 10 seconds from start? ex: 00:00:10
// picname..... name your generated pic

exec("START c:/ffmpeg/ffmpeg -vcodec png -i movie.avi -ss 00:00:00 -vframes frames picname%d.png");

?>
