Gtk gui on a cgi perl program
 

I am wanting to call a program, avidemux2, through my web cgi program to encode some files.
However, The program automatically opens a gtk gui, which does nothing for my needs.
How, in perl, can I pipe this gui into /dev/null? I dont want the program to mess up because of it, but I dont want to see the gui either(dont want to get a gtk error).

avidemux is a gtk application... that's the point of it.... maybe you'd do better with mencoder (part of mplayer)

Linux is built off command line interfaces. If I wanted graphic apps I would use windows.
I want automation. mencoder/transcode does not read .nuv files(atleast not that I have seen work).
If you can prove me otherwise, I will take a look, but right now i want to discard the gui.

Any ideas?
