I believe you wanted to extract some info from an MPEG file? So look for a program which does simply that, ie without trying to play the damn thing. There is a project based on PHP which extracts various info from various format multimedia files. That may or may not do what you want.

In php.ini, once you've enabled it, restart webserver and see what errors, if
any, you get.

you are allowed to access those executables?
i am running in safe mode.

Are you able to execute any shell programs/commands at all? Hint try something
simple like shell_exec('touch /tmp/testfile') and see whether /tmp/testfile
is being created.

ok, i have enabled that with error_reporting(E_ALL);

Yes, i do have acces to those files and the permissions are correct.

Yes, i am.

Re: [PHP] shell_exec with pipes
ok, i am running the script like this now: START - $var=shell_exec(/home/lansinplayer/server/apache/htdocs/lansinplayer/getfilelength.sh /tmp/pitstop.mpeg); echo --$var--; STOP - Where echo returns nothing. I did a chmod 777 on the getfilelength.sh file.
