• How to check for corrupt mp3 files using ffmpeg in nodejs

  2 septembre 2022, par Oliver Wagner

  Using the 'ffmpeg-static' npm package I managed to integrate ffmpeg in my node application, and run the [example][1]https://github.com/eugeneware/ffmpeg-static/blob/dce6d42ba772a5769df8181e704772db4456ef16/example.js code.

  


  The gist of the code is :

  


  import pathToFfmpeg from "ffmpeg-static";
import shell from 'any-shell-escape';
import { exec } from "child_process";

 function runFfmpeg(src, dest) {
  //where src is a existing mp3 file in a folder and dest is the destination folder
  const script = shell([
    pathToFfmpeg,
    '-y', '-v', 'error',
    '-i', resolve(process.cwd(), src),
    '-acodec', 'mp3',
    '-format', 'mp3',
    resolve(process.cwd(), dest),
  ]);

  exec(script);
}


  


  This works and this decodes and encodes the source file into mp3 and saves it in the dest folder.

  


  However, when I try what should be the simplest ffmpeg terminal command, such as ffmpeg -i file.mp3 -hide_banner it does not work. I have tried

  


  function runFfmpeg(src, dest) {
  const script = shell([
    pathToFfmpeg,
    '-i', resolve(process.cwd(), src), '-hide_banner'
  ]);

  const fileInfo = exec(script);
  return fileInfo;



  


  In the end, where I want to get to is being able to use my runFfmpeg function to check if an mp3 file has any missing or corrupted frames, using a terminal command that I found in the interwebs :
ffmpeg -v error -i video.ext -f null

  


  Any ideas on how to do that ?

  


• What's the simplest way of installing ffmpeg on my server (on a Mac) ?

  13 octobre 2011, par Nick

  I am looking to install ffmpeg on my server to enable audio files uploaded to a website to be converted to MP3. I understand that I need to install ffmpeg and ffmpeg-php, but I am not sure how to do this. I am wondering what the simplest way of doing this would be on my Mac. Would I need to use Terminal and learn command line methods, or is there a simpler way ? I have checked with my host that I have SSH access.
