Constructor Details

CvSource

public CvSource(String name, VideoMode mode)

Create an OpenCV source.

Parameters:

name - Source name (arbitrary unique identifier)

mode - Video mode being generated

CvSource

public CvSource(String name, VideoMode.PixelFormat pixelFormat, int width, int height, int fps)

Create an OpenCV source.

Parameters:

name - Source name (arbitrary unique identifier)

pixelFormat - Pixel format

width - width

height - height

fps - fps

Method Details

putFrame

public void putFrame(Mat image)

Put an OpenCV image and notify sinks.

Only 8-bit single-channel or 3-channel (with BGR channel order) images are supported. If the format, depth or channel order is different, use Mat.convertTo() and/or cvtColor() to convert it first.

Parameters:

image - OpenCV image
