JavaCV之FFmpegFrameFilter视频转灰度

1、代码

package com.example.demo.ffpemg;import lombok.SneakyThrows;
import org.bytedeco.javacv.*;public class FFmpegFrameFilterVideoExample {@SneakyThrowspublic 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。");}
}
