我在Windows中有一个简单的网络摄像头程序“偶尔”工作,但大多数时候它在尝试查找默认驱动程序时挂起。
public class JavaApplication54 {
/**
* @param args the command line arguments
*/
public static void main(String[] args) throws IOException {
Webcam webcam = Webcam.getWebcams().get(0);
webcam.open();
BufferedImage image = webcam.getImage();
ImageIO.write(image, "PNG", new File("test.png"));
image = null;
webcam.close();
}
} 我得到的输出是

如果我更正,这是Webcam Capture API代码中发现的死锁问题之一。有关详情,您可以在Webcam Capture Github project页面查看这些门票:#128,#30
我认为您的解决方案是使用最新版本,这是(我写这个答案的时候)0.3.10-RC6。无论用于开发的IDE(或CLI)如何,它都应该有效。
