JVM crash error

[jetamie]

Pseudocode

public class Demo {
   private final static OpenCVFrameConverter.ToMat converter = new OpenCVFrameConverter.ToMat();
    public static void main(String[] args) throws Exception {
                      FFmpegFrameGrabber grabber = new FFmpegFrameGrabber("test.mp4")
                      grabber.start();
                      Frame img = null;
                      while((img = grabber.grabImage()) !=null ) {
                          Mat mat = converter.convert(img);
                          //todo do something
                      }
     }
}

It worked very well at first, and I would repeat this logic over and over again, and immediately after a while, the JVM crashed, and here is the screenshot

Please call grabber.stop() at the end.

Please call grabber.stop() at the end.

Sorry, I didn't write completely above, I used grabber.restart()

Please call grabber.stop() at the end.

Do I need to reinitialize the ToMat object？

restart() might not always work. Try not to use it see if it works.

I need to read video frames in a loop, similar to FFmpeg's --loop parameter function

Creating multiple instances of FFmpegFrameGrabber should do what you need.
