How can I convert an AVI file to FLV format with PHP?

Is it possible to convert an AVI file to FLV format with PHP? If so, how? I don't need a complete solution, just a hint on how to do it.

ffmpeg is a great library for this sort of thing. Here's a walkthrough of the process:

It would be simpler to convert the video into Flash video and just use one of the many Flash video players out there. There is also an ffmpeg api for PHP, this would be a good place to start.

Assuming you have ffmpeg installed, you can do this:

<?php
   define('FFMPEG_LIBRARY', '/usr/local/bin/ffmpeg ');
   $exec_string = FFMPEG_LIBRARY.' -i inputfile.avi outputfile.flv';
   exec($exec_string);
?>

Call a command line transcoder like Mencoder or vlc. Alternatively, look for a PHP library which allows you to access a library like ffmpeg.
