IDEAS anyone? creating /dev/videoX device and Stream Video through it

Hey Guys,

so i have a little Problem:

I need to testdrive a motion/object recognition software. This nifty peace of sh** is not available as sources and does only accept streams coming from /dev/videox . (Cannot not be fed with videos)
You could argue : "Plug the camera in and there u go...." but I dont have this kind of (expensive) camera right now.

Some evidence I found on the net:

webcamstudio does such kind of thngs but in fact I need (prefer) a linux way like:

ffmpeg somevideo | todevX

Could you do something like "ffmpeg somevideo > /dev/devicehere"

Or maybe something like mplayer? I don't know the commands, but have mplayer play the video, then send output to /dev/devicehere

You need to create that /dev/videoX somehow. Maybe a webcam would do?
