[Vloopback] Compatible webcams

Question

Hi guys, thank you for your work, it is really helpful for me!

I am working on a multitouch-multicam project on ubuntu (9.04 Jaunty Jackalope). I use 4 cams for my project, and put in real time together the 4 images into one big image (thanks to OpenCV). I'd like to use Vloopback to output the big final image on a virtual cam.

For now, I have tried vloopback with two different cameras (i run the "invert" example) :

- logitech quickcam messenger, working with v4l => it works

- philips spc 1030 working with v4l2 => it doesn't work (you can see the error output under this)

My questions are : => is there a way to make a v4l2 cam work with vloopback => do you have a list of "vloopback compatible" webcams? => It seems that v4l webcams are the old ones, are there any modern/efficient cams (30 fps, 1280x1024) that work with v4l and/or vloopback compliant

I hope my questions are clear, please let me know if you have any idea/suggestion/question

Thank you

Seb

Follow Up

Vloopback doesn't work with V4L2 unless driver has backward compatibility with V4L like pwc does.
