Hello guys,
Many many many thanks to all of you for your help.
I am pretty sure that the video_pipe option is the way to go. Theoretically
it solves the problem.
To use this option I need the v4l2loopback-dkms package, and I am having
problems installing it because it is a kernel module and my headers don't
match my kernel blablabla.
Unfortunately I can't continue with this project for the next days, but
when I am back I will try to get it working!
Thanks a lot to all of you! You will hear from me soon
