@lkundrak @oleksandr hmm... so i keep width and height variable and turn min/max geometry to plain compile-time macros (v4l2-loopback allows to define hard limits at run-time which does not sound like too good idea...)

thanks (i guess) :-)

@lkundrak @oleksandr as per security. Also, I think for the sake of security i limit the video driver to be only capture device. A pure producer is least harmful as per security (and simplifies the implementation whole a lot).
