v4l2loopback and kernel-3.7

["forum::für::umläute" <zmoelnig@umlaeute.mur.at>]

hi all,

i'm currently maintainer of the "v4l2loopback" device [1], a virtual
video device that allows applications to share video-streams via the
v4l2 API (each device being V4L2_CAP_VIDEO_CAPTURE | V4L2_CAP_VIDEO_OUTPUT).

now (unfortunately for someone maintaining a driver) i have not been
following development of the linux-kernel very closely (mainly using
debian unstable kernels myself), but some of my users do.
it seems that with newer kernel-versions the functionality for
video-output modules have been somehow removed from the kernel (3.7.1
has been confirmed to make troubles, whereas 3.6.10 still works).

i'd like to inquire, what happened in/to the mainstream kernel, and
what's the supposed way to proceed for a virtual video device like mine.
(i naively ask the question here, as i'm a bit afraid of kernel-dev
mailing list :-))

what's more, if the v4l2-taskforce would be interested to take over a
kernel-module that - to my knowledge - is currently the only feasible
way on linux to exchange live video streams between applications, we
might talk about that :-)
