Need to have a website run a lengthy, FFMPEG'ing script

[tibberous]

I wrote a PHP script that uses FFMPEG to encode multiple mp3 files in a directory. I script works perfectly when called from the command line, but I can't get it to run in the background.

 

I've tried:

php /home/express/www/scripts/processMusic.php > /dev/null &

php /home/express/www/scripts/processMusic.php < /dev/null > /dev/null &

php /home/express/www/scripts/processMusic.php &

 

But nothing works...

 

And php /home/express/www/scripts/processMusic.php < /dev/null > /dev/null & works from the command line, but not from within a webpage.

 

To make things weirder, the script I wrote run, just the ffmpeg commands don't work...

 

Am I just not able to start a background process from a background process?

[jonsjava]

while [ 1 ]; do `php /home/express/www/scripts/processMusic.php -q`;sleep 3; done;

This will run forever

Thing is, I want to call it from a web page. If it runs forever, the page won't load.
