这个项目使用JavaCV库处理视频文件
包含视频读取、处理和保存的基本功能
使用Maven构建可执行JAR文件
可以通过命令行参数指定输入输出文件
需要Java 11或更高版本运行
源码部分：

import org.bytedeco.javacv.;
import org.bytedeco.opencv.opencv_core.;

public class VideoProcessor {
private FFmpegFrameGrabber grabber;
private FFmpegFrameRecorder recorder;
private String inputPath;
private String outputPath;

public VideoProcessor(String input, String output) {
    this.inputPath = input;
    this.outputPath = output;
}

public void processVideo() throws Exception {
    grabber = new FFmpegFrameGrabber(inputPath);
    grabber.start();

    recorder = new FFmpegFrameRecorder(outputPath, 
        grabber.getImageWidth(), grabber.getImageHeight());
    recorder.setVideoCodec(grabber.getVideoCodec());
    recorder.setFrameRate(grabber.getFrameRate());
    recorder.start();

    Frame frame;
    while ((frame = grabber.grab()) != null) {
        // 这里可以添加视频处理逻辑
        recorder.record(frame);
    }

    recorder.stop();
    grabber.stop();
}

}

class Main {
public static void main(String[] args) {
if (args.length < 2) {
System.out.println("Usage: java -jar video-processor.jar ");
return;
}

    VideoProcessor processor = new VideoProcessor(args[0], args[1]);
    try {
        processor.processVideo();
        System.out.println("Video processing completed successfully!");
    } catch (Exception e) {
        System.err.println("Error processing video: " + e.getMessage());
    }
}
