JavaCV之FFmpegFrameFilter视频转灰度

1、代码

java 复制代码

package com.example.demo.ffpemg;


import lombok.SneakyThrows;
import org.bytedeco.javacv.*;

public class FFmpegFrameFilterVideoExample {
    @SneakyThrows
    public static void main(String[] args) {

        // 输入视频文件路径
        String inputVideoPath = "f:/2222.mp4";
        // 输出视频文件路径
        String outputVideoPath = "f:/2222output_video.mp4";

        // 抓取器，用于读取输入视频
        FFmpegFrameGrabber grabber = new FFmpegFrameGrabber(inputVideoPath);
        grabber.start();

        // 创建帧过滤器，这里使用一个简单的视频滤镜（例如：将视频转为灰度）
//        传入滤镜参数（这里是format = gray，用于将视频转换为灰度）
//        、视频宽度和高度。同时设置像素格式为AVPixelFormat.GRAY8和帧率为抓取器获取的帧率，并启动帧过滤器。

        FFmpegFrameFilter frameFilter = new FFmpegFrameFilter("format=gray", grabber.getImageWidth(),
                grabber.getImageHeight());
        frameFilter.setFrameRate(grabber.getFrameRate());
        frameFilter.start();

        // 用于写入输出视频的帧记录器
        FFmpegFrameRecorder recorder = new FFmpegFrameRecorder(outputVideoPath, grabber.getImageWidth(),
                grabber.getImageHeight());
        recorder.setVideoCodec(grabber.getVideoCodec());
        recorder.setFormat("mp4");
        recorder.setFrameRate(grabber.getFrameRate());
        recorder.setAudioChannels(grabber.getAudioChannels());
        recorder.setAudioCodec(grabber.getAudioCodec());
        recorder.start();

        Frame frame;
        while ((frame = grabber.grab()) != null) {
            //从抓取器中抓取帧，将其推送（push）到帧过滤器中，然后通过pull方法获取经过滤镜处理后的帧
            // 。如果设置了帧记录器（在代码中部分注释掉了），可以将处理后的帧记录到输出视频文件中。
            frameFilter.push(frame);
            Frame filteredFrame = frameFilter.pull();
            recorder.record(filteredFrame);
        }

        frameFilter.stop();
        grabber.stop();
        recorder.stop();
        frameFilter.release();
        grabber.release();
        recorder.release();

        System.out.println("视频滤镜处理完成。");

    }
}
