webcam-capture

This is the standard Aussom-Lang webcam capture module. It provides webcam discovery and frame capture support based on webcam-capture by Sarxos v0.3.12, which is distributed under the MIT license.

The module exposes a static WebcamCapture class for device discovery and a Webcam class for capturing single frames, streaming frames asynchronously, and saving images to disk.

Usage

Here's a short example, please see the API doc for details.

// Get the default webcam
cam = WebcamCapture.getDefault();

// Pick a resolution the device supports
sizes = cam.getViewSizes();
cam.setViewSize(sizes[0][0], sizes[0][1]);

// Open in async mode so streaming methods work
cam.open(true);

// Save a single frame to disk
cam.saveImage('frame.png');

// Stream frames to a callback
cam.startStream(::onFrame, 10.0);
sys.sleep(2000);
cam.stopStream();

// Close the device
cam.close();

public onFrame(Frame) {
    c.log('Got a frame of size ' + Frame.size());
}
