如何在Android中使用ffmpeg合并音视频文件？

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;

public class FFmpegUtils {
    public static void mergeAudioVideo(String audioPath, String videoPath, String outputPath) {
        try {
            // 构建FFmpeg命令行
            String[] cmd = {"-i", audioPath, "-i", videoPath, "-c", "copy", outputPath};

            // 创建进程并执行命令行
            ProcessBuilder processBuilder = new ProcessBuilder(cmd);
            Process process = processBuilder.start();

            // 读取命令行输出
            BufferedReader reader = new BufferedReader(new InputStreamReader(process.getErrorStream()));
            String line;
            while ((line = reader.readLine()) != null) {
                // 处理命令行输出
            }

            // 等待命令行执行完成
            process.waitFor();

            // 关闭输入流和进程
            reader.close();
            process.destroy();
        } catch (IOException | InterruptedException e) {
            e.printStackTrace();
        }
    }
}
