[MEncoder-users] PHP cannot execute some encoding commands

Mon Sep 4 04:30:15 CEST 2006

Hi Ivo, 

  Sorry for the late reply. I tried as you suggested. And I got this log file. I am not so sure what exactly is wrong. But the message comes out from log file definately is different from how the message look like when I run the same command on the Linux itself. Sorry for no proper indent. But I don't know if you can tell what's wrong from my log file. I paste the whole log here. Hope you can help me out. 

  Regards,

  Leo

Try redirecting stdout/stderr to a file. Something like:

exec('mplayer -v -frames 5 -vo jpeg:outdir=somedir:quality=100 -contrast 20 
>logfile.log 2>&1');

Notice that I added -v so the output will be more verbose. Now look at 
logfile.log to see what actually happened and why it failed.
