问在nodejs上使用ffmpeg拼接mp4视频文件

EN

const glob = require("glob");

//store all the filenames with path to the videos
var inputVideos = glob.sync("/home/r/clips/*.mp4");
const output = "./output/output.mp4";

const util = require("util");
const exec = util.promisify(require("child_process").exec);

async function concatVideos(inputVideos, outputVideoPath) {
  

  //imported to get the name of videofile easily
  var path = require("path");

  //the next ffmpeger variable,will keep the lines
  //ffmpeg -i videofile1.mp4 -c copy -bsf:v h264_mp4toannexb -f mpegts intermediate_videofile1.ts
  //ffmpeg -i videofile2.mp4 -c copy -bsf:v h264_mp4toannexb -f mpegts intermediate2_videofile2.ts

var ffmpeger = "";
  ffmpeger = inputVideos
    .map(
      video =>
        ` ffmpeg -i ${video} -c copy
    -bsf:v h264_mp4toannexb -f mpegts ./intermediate_${
      path.parse(video).name
    }.ts`
    )
    .join("\n");

  //concatenator keeps the segment
  //"concat:intermediate_videofile1.ts|intermediate_videofile2.ts"
  var concatenator = '"concat:';
  concatenator +=
    inputVideos
      .map(video => `./intermediate_${path.parse(video).name}.ts`)
      .join("|") + '"';

  await exec(
    `
    ${ffmpeger}
    ffmpeg -i ${concatenator} -c copy -bsf:a aac_adtstoasc ${outputVideoPath}`
  );
}
concatVideos(inputVideos, output);

concat:./intermediate_0.ts|./intermediate_1.ts|./intermediate_2.ts|./intermediate_3.ts|./intermediate_4.ts|./intermediate_5.ts|./intermediate_6.ts|./intermediate_diegoortiz1399.ts|./intermediate_dog.ts|./intermediate_dogstify.ts|./intermediate_dylan50568.ts|./intermediate_gabrieleecorrea.ts|./intermediate_golden_leo.ts|./intermediate_helenapatiih.ts|./intermediate_kaiobreno2.ts|./intermediate_khancorso.ts|./intermediate_kitakaze_s_lili.ts|./intermediate_oliver45743.ts|./intermediate_pinkie_pets.ts|./intermediate_shibakoma.ts|./intermediate_thepetcollective.ts|./intermediate_tod_the_foxx.ts|./intermediate_userpub3y9m7kb.ts|./intermediate_warriorbulldogs.ts: No such file or directory```

So the command line would be:
