Invalid argument when using fluent-ffmpeg to concatenate two video files

DGLcsGaming commented 2 years ago

Version information

fluent-ffmpeg version: 2.1.2
ffmpeg version: git-2022-10-25-9bed814-ffmpeg-windows-build-helpers
OS: Windows 10 (21H2)
Nodejs: v14.18.3

So I'm trying to use fluent-ffmpeg to concatenate (using concat demuxer) two .mp4 videos files (identical video/audio formats) but I'm getting this error:

Error: ffmpeg exited with code 1: ":../../input.txt": Invalid argument

Code to reproduce

const ffmpeg = require('fluent-ffmpeg');
.
.
const mergeVideoImageWithOriginalVideo = (imageVideo) => {
  return new Promise((resolve, reject) => {
    const command = new ffmpeg();
    command
      .input(`"../../${imageVideo.replace('./', '')}"`)
      .inputFormat('concat')
      .inputOptions(['-safe 0'])
      .outputOptions(['-c copy'])
      .on('start', function (ffmpegCommand) {
        console.log(ffmpegCommand);
      })
      .on('progress', function (data) {
        /// do stuff with progress data if you want
      })
      .on('end', function () {
        resolve();
      })
      .on('error', function (error) {
        return reject(new Error(error));
      })
      .save(`"../../${imageVideo.replace('txt', 'final.mp4').replace('./', '')}"`)
      .run();
  });
};

The contents of input.txt:

file 'video.image.mp4'
file 'video.mp4'

The output of console.log(ffmpegCommand) is:

ffmpeg -f concat -safe 0 -i "../../input.txt" -y -c copy "../../video.final.mp4"

Expected results

Concatinate both video files into a video.fina.mp4

Observed results

The weird thing is when I run that exact command (using CMD) in the same directory that I'm running this nodejs script it works.

Hi. Did you find out why it did not work in the end?
