Anyone use /usr/bin/convert successfully in PHP or cron job?

[prosumer]

I'm getting a zero-byte output (video.mpg) running this shell command within PHP.

 

#!/usr/bin/ksh
/usr/local/bin/convert /home/myfolder/image*.jpg /home/myfolder/video.mpg

 

If I execute the following from the terminal, I get the correct output.

convert image*.jpg video.mpg 

However, if I do it in PHP or cron job, I'll get a zero-byte file.

 

I also tried :

<?php
exec("convert image*.jpg video.mpg");
?>

<?php
shell_exec("convert image*.jpg video.mpg"); 
?>

or even wrap the above in a script.sh and then do a exec("sh script.sh") in PHP.

All of the above give my a zero-byte output.

 

Did I overlook something obvious? I hope so...

Please enlighten

Ok, never mind.

I found the solution.

 

Just add the PATH to my mpeg2encode codec in the above script and it works

 

Thanks for viewing.
