Can't get any camera in MacOS using example code?Any help?

[yongxin100]

Hi I launched a project in IDEA IDE and running example code of project:

       List<Webcam> webcam = Webcam.getWebcams(1000*50);
        if (webcam != null) {
            System.out.println("Webcam: " + webcam.size());
        } else {
            System.out.println("No webcam detected");
        }

But i got zero size of webcam list!!!

When i am using the default camera app PhotoBooth ,i can see both usb camera i attached to MacBook and internal camera.

It is something related to MacOS's permission strategy??

Thanks a lot!

ok, I 've solved the problem by following steps: 1、 use snapshot version of webcam-capture. 2、add nativelibs4java dependency to pom of the my project The POM files as following:
