🤓

1️⃣配置Maven    在pox.xml中加入

<dependencies>
    <dependency>
          <groupId>org.bytedeco</groupId>
          <artifactId>javacv-platform</artifactId>
          <version>1.5.7</version>
     </dependency>
</dependencies>

2️⃣创建FrameExtractor

import org.bytedeco.javacv.*;

import javax.imageio.ImageIO;
import java.awt.image.BufferedImage;
import java.io.File;
import java.io.IOException;

public class FrameExtractor {
    public static void main(String[] args) {
        // 视频文件路径
        String videoFilePath = "/Users/canna/···/XXX.mp4";//此处写自己的视频路径
        // 创建FFmpegFrameGrabber对象
        FFmpegFrameGrabber grabber = new FFmpegFrameGrabber(videoFilePath);
        try {
            // 打开视频文件
            grabber.start();
            // 逐帧抓取视频
            Frame frame;
            int frameNumber = 1;
            while ((frame = grabber.grabImage()) != null) {
                BufferedImage bufferedImage = frameToBufferedImage(frame);
                // 生成保存帧图像的文件路径
                String outputFilePath = String.format("%s/frame_%05d.jpg", "/Users/canna/···/XXX", frameNumber);//此处写自己的保存路径

                // 保存帧图像到文件
                try {
                    ImageIO.write(bufferedImage, "jpg", new File(outputFilePath));
                    System.out.println("保存帧图像：" + outputFilePath);
                } catch (IOException e) {
                    e.printStackTrace();
                }
                frameNumber++;
            }
            // 关闭视频文件
            grabber.stop();
        } catch (org.bytedeco.javacv.FrameGrabber.Exception e) {
            e.printStackTrace();
        }
    }

    /**
     * 将Frame转换为BufferedImage
     */
    private static BufferedImage frameToBufferedImage(Frame frame) {
        Java2DFrameConverter converter = new Java2DFrameConverter();
        return converter.getBufferedImage(frame);
    }
}

3️⃣运行   结果如下
