Device driver that generates video pipes

The video4linux loopback device is a device driver that generates video pipes. It lets a user program feed a video stream to another as if it were coming from an actual video4linux device. To achieve this a video pipe consists out of two video4linux devices: one for the generating program to write its data to and one for a normal video4linux program to read from. At the moment there are only a few programs that can feed the input of the pipe: invert and resize, the example programs with the driver and motion, a motion detection program.
