(description "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. this allows you for instance
to apply some nifty video effects on your Jitsi video... it also allows some
more serious things (e.g. using it to add streaming capabilities to an
application by the means of hooking GStreamer into the loopback devices).")
(synopsis "Linux kernel module to create virtual V4L2 video devices")
(description
"This Linux module creates virtual video devices. @acronym{V4L2, Video
for Linux 2} applications will treat these as ordinary video devices but read
video data generated by another application, instead of a hardware device such
as a capture card.
This lets you apply nifty effects to your Jitsi video, for example, but also
allows some more serious things like adding streaming capabilities to an
application by hooking GStreamer into the loopback device.")
