%description
Allows creation of virtual video devices. Normal (v4l2) applications will read these devices as if they were ordinary video devices.

Summary:  Kernel module (kmod) for %{name}
Requires: kernel-devel

%description kmod
This module allows you to create "virtual video devices". Normal (v4l2) applications will read these devices as if they were ordinary video devices, but the video will not be read from e.g. a capture card but instead it is generated by another application.
