在javacv中使用高像素摄像头获取错误？

Question

我在运行程序错误时遇到错误，如下所示

com.googlecode.javacv.FrameGrabber$Exception: videoInput.getPixels() Error: Could not get pixels.
    at com.googlecode.javacv.VideoInputFrameGrabber.grab(VideoInputFrameGrabber.java:168)
    at Robot.run(Robot.java:107)
    at java.lang.Thread.run(Unknown Source)

***** VIDEOINPUT LIBRARY - 0.1995 - TFW07 *****

SETUP: Setting up device 0
SETUP: HD Pro Webcam C920
SETUP: Couldn't find preview pin using SmartTee
SETUP: Capture callback set
SETUP: Device is setup and ready to capture.

和错误显示在下面的行中

rameGrabber grabber = new VideoInputFrameGrabber（0）; // 1用于下一个相机

grabber.start();
        IplImage img = null;
        while (true) {
             long sleepTime= (long)((100000 / 60));
             Thread.sleep(sleepTime);
                img = grabber.grab();//gettin error on this line..

我遇到了类似的问题。答案是在这个论坛（https://groups.google.com/forum/#!msg/javacv/yD99RSl7oCI/KQIRoOIqcK4J）

尝试使用javaCV.OpenCVFrameGrabber而不是VideoInputFrameGrabber。

改变'FrameGrabber grabber = new VideoInputFrameGrabber（0）; // 1为下一个相机'

'Frame Grabber grabber = new OpenCVFrameGrabber（0）; // 1 for nest camera'

现在它每次都适合我。

希望能帮助到你！
