I want to convert any videos to FLV format.

code:

---

<?php
convertToFlv( "test.avi", "test.flv" );

function convertToFlv( $input, $output ) {
   echo "Converting $input to $output<br />";
   $command = "ffmpeg -i $input -s 320x240 -ar 44100 -r 12 $output";
   echo "$command<br />";
   shell_exec( $command );
   echo "Converted<br />";
}
?>

---

For some reason, it doesn't output anything.
What am I missing here?
