    Class FrameProcessor

    Frame Processor Simplifies grabbing frames from a camera or video file.

    First, create:

    const fp = new FrameProcessor();

    Then either use the camera or a video file:

    fp.useCamera(constraints);
    // or:
    gp.useVideo(file);

    With useCamera, optionally specify Camera.Constraints to pick which camera and resolution.

    fp.getFrame(); // Gets the last frame
    fp.dispose(); // Close down camera/file

    See FrameProcessorOpts for details on available options.
