Launching VLC from PHP

[dignified]

In Linux, I'm trying to launch vlc from a php script that I have written by using the following code:
------------------------------------------------------
shell_exec("nice -10 vlc -vvv v4l:/dev/video:norm=ntsc:frequency=283262:size=320x240:channel=0:adev=/dev/dsp:audio=0
--sout '#transcode{vcodec=mp4v,acodec=mpga,vb=1000,ab=128,vt=800000,keyint=80,deinterlace}:std{access=udp,mux=ts,url=224.0.0.0}' &> /dev/null &");
-------------------------------------------------------
I get no errors, but VLC doesn't get spawned into a process. When I pipe all output into a regular file I get the following information:

Gtk-WARNING **: cannot open display:
[00000157] main private debug: waiting for thread completion

anyone know how I can fix this?

It's trying to open an interface...
Which isn't possible without X11

Try launching it with... vlc -I dummy or vlc -I http
The last will open a web interface at port 8080 of the host.
If you want you can change the webinterface as well.
