Detailed Description

OpenCV's VideoCapture-based streaming source.

This class implements IStreamSource interface. Its constructor takes the same parameters as cv::VideoCapture does.

Please make sure that videoio OpenCV module is available before using this in your application (G-API doesn't depend on it directly).

Note

stream sources are passed to G-API via shared pointers, so please gapi::make_src<> to create objects and ptr() to pass a GCaptureSource to cv::gin().
