If VIDIOC_G_FMT fails this means, that the loopback device did not support the
selected format. That's a real problem then...
v4l2sink gets the list of supported formats by using the VIDIOC_ENUM_FMT ioctl.
For the sink it should maybe assume that all possible V4L2 formats are
supported if nothing is returned here (or even better if it's possible to
detect that this is a loopback device).
A capsfilter before the v4l2sink should work in any case though, just make sure
that you have appropiate converters before the capsfilter.
