Spring Boot 3整合FFmpeg进行图片和MP3转换为视频

Spring Boot 3整合FFmpeg进行图片和MP3转换为视频的示例代码如下：

添加FFmpeg依赖到pom.xml：

<dependency>
    <groupId>com.github.kokorin.jaffree</groupId>
    <artifactId>jaffree</artifactId>
    <version>0.1.2</version>
</dependency>

创建一个服务类来执行转换：

import com.github.kokorin.jaffree.ffmpeg.FFmpeg;
import com.github.kokorin.jaffree.ffmpeg.FFmpegResult;
import org.springframework.stereotype.Service;
 
import java.nio.file.Paths;
 
@Service
public class VideoConversionService {
 
    public void convertImageAndAudioToVideo(String imagePath, String audioPath, String outputPath) throws Exception {
        FFmpegResult result = FFmpeg.atPath()
                .addInput(FFmpeg.input(imagePath))
                .addInput(FFmpeg.input(audioPath))
                .overrideOutputFiles(true)
                .addOutput(FFmpeg.output(outputPath)
                        .videoCodec("copy")
                        .audioCodec("copy"))
                .execute();
 
        if (result.getState() == FFmpegResult.State.SUCCESS) {
            System.out.println("转换成功");
        } else {
            System.out.println("转换失败");
        }
    }
}

在Spring Boot应用的主类或者任意一个配置类中，调用转换服务：

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.CommandLineRunner;
import org.springframework.stereotype.Component;
 
@Component
public class VideoConversionRunner implements CommandLineRunner {
 
    @Autowired
    private VideoConversionService videoConversionService;
 
    @Override
    public void run(String... args) throws Exception {
        String imagePath = "path/to/image.jpg";
        String audioPath = "path/to/audio.mp3";
        String outputPath = "path/to/output.mp4";
 
        videoConversionService.convertImageAndAudioToVideo(imagePath, audioPath, outputPath);
    }
}
