This extension deals with capture devices (typically camera). It can display camera stream, track up to 2 colors on camera image and save frame or video stream to a file.
It is using the Opencv library that is the reason why it is a big extension but it does not need any extra Dlls.
I tested it on some hardware but I am waiting for your feeback to see if it is working properly on a larger range of devices.
The beta version (v0.5) is here: OpenCapture.zip
