使用nodejs合并mp4文件格式的两个视频

const { exec } = require('child_process');

function mergeVideos(video1Path, video2Path, outputPath) {
  const command = `ffmpeg -i ${video1Path} -i ${video2Path} -filter_complex "concat=n=2:v=1:a=1" -c:v libx264 -crf 23 -preset veryfast -c:a aac -b:a 128k ${outputPath}`;

  exec(command, (error, stdout, stderr) => {
    if (error) {
      console.error(`合并视频时出错：${error.message}`);
      return;
    }
    console.log('视频合并完成');
  });
}

const video1Path = '/path/to/video1.mp4';
const video2Path = '/path/to/video2.mp4';
const outputPath = '/path/to/output.mp4';

mergeVideos(video1Path, video2Path, outputPath);
