What would be really interesting is having a virtual device that would
be feeded by the gstreamer framework. I know that there is already
the v4l2sink. I've tried to make it work with v4l2loopback device but
with no success. If we were able to create a virtual device that
would be compatible with the v4l2sink of GStreamer, then imagine all
the possibilities, not only for webcamstudio, but for a bunch of
projects using GStreamer.
