[MEncoder-users] PHP cannot execute some encoding commands

[Ko Ko]

Hi
   
  When I use this command with PHP exec function it works fine. 
   
  mplayer -ss 5 -frames 5 -vo jpeg:outdir=$outdir:quality=100 -contrast 20 test.avi 
   
  After executing I got the 5 jpeg images from test.avi file in the output directory that I specified. 
   
  But when I use this command with PHP 
   
  mplayer -frames 5 -vo jpeg:outdir=$outdir:quality=100 -contrast 20 test.mpg
   
  It doesn't produce any jpeg images from test.mp file.
   
  I try out the same set of command on my Fedora itself as root or normal user it is manage to create output directory and produce the jpeg images. 
   
  I have no idea why PHP command won't execute this command correctly.
   
  Can anyone help me with this? =(
   
  Regards,
  Leo
