Virtual video device

Hi guys / girls(who knows)

It's a bit off the strict "archlinux" subject, but I have a technical challenge that I'd like to share with other experienced linux users / developers.

Here's the context : I'd like to implement some kind of virtual video device, that I could feed with some data (typically a feed from a "real" camera, post processed and mixed with other information, for video chat use).  I'v googled around for existing implementations, and found the following :

* http://www.lavrsen.dk/foswiki/bin/view/ … backDevice
* http://v4l.videotechnology.com/vivi.html
* http://v4l2vd.sourceforge.net/

but unfortunately all of these solutions require kernel-space intervention.  I ideally would like to remain exclusively on the user-space side, for ease of redistribution and maintenance.  I think there's also a possibility using gstreamer, that has a v4lsink element I think, but gstreamer is not something I'm very familiar with.

Anyone of you having any ideas how I could do that?  I will seriously start looking in-depth at the V4L2 API, but any lead to narrow down my researches would be welcome.

Thanks in advance,
