我创建了一个从视频中捕获帧的类.捕获帧时,它将保存为图片.当视频是.avi时,应用程序运行正常.格式为.avi时.
public static void main(String[] args) {
FFmpegFrameGrabber grabber = new FFmpegFrameGrabber("C:/Users/Ioanna/Desktop/video1.avi");
try {
IplImage img;
//Start grabber to capture video
grabber.start();
//grab video frame to IplImage
img = grabber.grab();
if (img != null) {
//save video frame as a picture
cvSaveImage("capture.jpg",img);
}
}catch (Exception e) {
}
}
错误是
Exception in thread "main" java.lang.ExceptionInInitializerError

有谁知道这是什么问题？
