• Audio Downloader from YouTube with youtube-dl and ffmpeg [closed]

  22 janvier 2021, par Um9vdAo

  I am trying to make an audio downloader with youtube-dl and ffmpeg which will :
  

  


  


  

  1. Download the best format of audio available on YouTube
     

  


  2. Embed thumbnail in the file.

  


  3. Convert the file to mp3.

  


  4. Delete everything from the folder except the converted mp3 file.
     

  


  


  


  Below is the code I've come up with :

  


  @echo off
cls
set /p playlist="Enter YouTube Link: " 
youtube-dl --cookies cookies.txt -f bestaudio[ext=m4a] -i --write-thumbnail --embed-thumbnail --max-sleep-interval 30 --min-sleep-interval 10 -o "%%(title)s.%%(ext)s" %playlist% --exec "ffmpeg -i {} -codec:a libmp3lame -qscale:a 0 {}.mp3 && del {}"


  


  The issues I've been facing with my code :

  


  

  1. The converted file is not renamed correctly. It's named Filename.m4a.mp3 where I want it to be named Filename.mp3
     

  


  2. Video thumbnail is saved as Filename.jpg and youtube-dl creates a file named cookies.txt. Those are not deleted automatically.

  


  3. Lastly, this error shows up :

  


  


  


  [swscaler @ 00000143e0a4ffc0] deprecated pixel format used, make sure you did set range correctly
[mp3 @ 00000143e09f0340] Frame rate very high for a muxer not efficiently supporting it.
Please consider specifying a lower framerate, a different muxer or -vsync 2

  


  


  I'd really appreciate it if you helped me fix those issues. Thanks !

  


• How do I use ffmpeg in my renderer process in electron ?

  16 juillet 2023, par Infinibyte

  I'm trying to use ffmpeg in my renderer process in my electron app. I expose the modules in my preload.js file like this :

  


  const { contextBridge, ipcRenderer } = require('electron');
const ffmpegStatic = require('ffmpeg-static');
const ffmpeg = require('fluent-ffmpeg');
// make ffmpeg available as a function in the renderer process
contextBridge.exposeInMainWorld('ffmpeg', () => ffmpeg(ffmpegStatic.path));


  


  And I try to acces it in my renderer.js file like this :

  


  video.addEventListener('change', (event) => {
    const file = event.target.files[0];
    const filePath = file.path;
    const fileName = file.name;
    const fileExt = fileName.split('.').pop();
    const newFileName = fileName.replace(fileExt, 'mp4');
    const newFilePath = filePath.replace(fileName, newFileName);

    // Run FFmpeg
    ffmpeg()

        // Input file
        .input(filePath)

        // Audio bit rate
        .outputOptions('-ab', '192k')

        // Output file
        .saveToFile(newFilePath)

        // Log the percentage of work completed
        .on('progress', (progress) => {
            if (progress.percent) {
                console.log(`Processing: ${Math.floor(progress.percent)}% done`);
            }
        })

        // The callback that is run when FFmpeg is finished
        .on('end', () => {
            console.log('FFmpeg has finished.');
        })

        // The callback that is run when FFmpeg encountered an error
        .on('error', (error) => {
            console.error(error);
        });
});


  


  But then I get following error in the console : Uncaught TypeError : ffmpeg(...).input is not a function at HTMLInputElement.
I really don't know how to fix this, can anyone help me ?

  


  I tried writing it differently and defining ffmpeg in my rendere.js but nothing worked...
