Video Four Linux Loopback Device Feeder
loopback feeder useful for development and testing.
Aimed to feed a v4l loopback device for testing purposes, also it's very useful to use it with Motion for development and testing because it triggers motion.
At the moment only a program has been implemented, dummyfill, which draws squares with random colours and random directions bouncing all the time, it does not consume much CPU and can be configured at execution time specifing FPS, colour-depth and resolution.
You need v4l or v4l2 support in your kernel, it's been tested with v4l loopback device versions > 0.91.
To install it just type make
Usage: dummyfill device widthxheight
Just run the program without parameters and it will output an example.
