# The reason why this package is a separate from the main one despite using the same sources
# is because akmods use the srpm to build the kmod package, and if the kmod package is included
# in the main package, akmods will reinstall the userspace package every time the kernel is updated.

# I made the mistake of combining the specs when I ported this from RPMFusion, but to be fair
# they barely document anything.

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.}
