I'm trying to concatenate several videos using FFmpeg with Nodejs. I'm receiving the "No such file or directory" error. The written code is:

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);

and the error is

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 mand line would be:

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 intermediate_videofile2.ts ffmpeg -i "concat:intermediate_videofile1.ts|intermediate_videofile2.ts" -c copy -bsf:a aac_adtstoasc ./output/output.mp4

Could you help us? Many thanks. Truly.:>

• Use the concat demuxer (documentation & wiki) instead of the concat protocol. You can avoid the temporary files with the concat demuxer. – llogan Commented Apr 3, 2020 at 4:47

Sorted by: Reset to default 3

So, the solution I found is in https://www.npmjs./package/ffmpeg-concat.

First install:

npm i ffmpeg-concat

Then: To concatenate videos:

const concat = require('ffmpeg-concat')
const glob=require('glob')

//an array of video path to concatenate
const videos=glob.sync('/home/username/Downloads/clips/*.mp4')

const output='./output/concatenated.mp4'

//a function to merge an array of videos with custom music
//and a transition fadegrayscale of 500ms duration between videos.
async function oneTransitionMergeVideos(){
  await concat({
   output,
   videos,
   audio:"/home/username/Downloads/music/music.m4a",
   transition: {
     name:"fadegrayscale",
     duration: 500
   }
})
}

oneTransitionMergeVideos()

It will concatenate a video, with audio, and transitions. Wohooo!!!

Use editly

npm i editly

Concat videos like this:

const clips = [
{
    layers: {
        type: "video",
        path: "path/to/clip1.mp4"
    }
},
{
    layers: {
        type: "video",
        path: "path/to/clip2.mp4"
    }
}
];
await editly({
    keepSourceAudio: true,   //to keep audio
    outPath: "./data/merged.mp4",
    clips: clips,
    //lot's of other great features
});

(I've spent a long day on ffmpeg and other non-nodejs solutions as well,this one is fare the easiest solution, altho using ffmpeg directly might be faster)
