• FFMPEG node.js using with ytdl

  25 juin 2024, par zlElo

  I have nodejs javascript code and I want that the video and the audio is downloaded, to combine it with ffmpeg. First, the video is longer that it should be, idk why. Second, the ffmpeg is not working because I'm getting an error, that ffmpeg can't find (but I installed fluent-ffmpeg via npm correctly)

  


  My code :

  


  const fs = require('fs');
const ytdl = require('ytdl-core');
const ffmpeg = require('fluent-ffmpeg');



// Function to download the youtube video
function download() {
    const linkInput = document.getElementById('linkInp');
    const resolution = document.getElementById('resolution');
    const videoTitle = document.getElementById('videoTitle');
    const videoAuthor = document.getElementById('videoAuthor');
    const videoUploadDate = document.getElementById('videoUploadDate');
    const videoPicture = document.getElementById('videoPic');
    const link = linkInput.value;
    console.log('Downloading following video from link: ', link, ' with resolution id: ', resolution.value);

    ytdl.getInfo(link).then((info) => {
        const format = ytdl.chooseFormat(info.formats, { quality: `${resolution.value}` });
        const videoFilePath = `${info.videoDetails.title}.${format.container}`;
        const audioFilePath = `${info.videoDetails.title}.mp3`;

        // before download, collect meta datas
        videoTitle.innerHTML = info.videoDetails.title;
        videoAuthor.innerHTML = info.videoDetails.author.name;
        videoUploadDate.innerHTML = info.videoDetails.uploadDate;
        videoPicture.src = info.videoDetails.thumbnails[0].url;

        // start downloading the video
        ytdl.downloadFromInfo(info, { format: format }).pipe(fs.createWriteStream(videoFilePath));

        // download audio separately
        ytdl.downloadFromInfo(info, { filter: 'audioonly' }).pipe(fs.createWriteStream(audioFilePath)).on('finish', () => {
            // merge video and audio after both are downloaded
            ffmpeg()
                .input(videoFilePath)
                .input(audioFilePath)
                .videoCodec('copy')
                .audioCodec('copy')
                .save(`${info.videoDetails.title}_with_audio.${format.container}`)
                .on('end', () => {
                    console.log('Video with audio merged successfully!');
                    fs.unlink(videoFilePath, (err) => {
                        if (err) console.error(err);
                    });
                    fs.unlink(audioFilePath, (err) => {
                        if (err) console.error(err);
                    });
                });
        });

    }).catch((err) => {
        console.error(err);
        document.getElementById('msg').style.display = 'block';
        document.getElementById('message').innerHTML = err;
    });
}


  


  Thanks for every help !

  


• ERROR : "Cannot Find FFMPEG" on Google Cloud Compute Engine Debian Wheezy 7.8 Managed Instance even though it's installed

  I wrote a Node.JS application that uses the fluent-ffmpeg module to watermark videos uploaded on the platform. I pushed the code to a my Google Cloud Compute Engine project, and every time I get Error : Cannot Find FFMPEG. I ssh’d into the instance once it was created and ran these commands to install FFMPEG before actually testing out the code. I am not sure what is causing the error because after this I am positive that FFMPEG is installed.

  sudo apt-get update
  
  sudo apt-get install -y ffmpeg
  
  export FFMPEG_PATH="/usr/bin/ffmpeg"
  
  export FFPROBE_PATH="/usr/bin/ffprobe"

  Below is my FFMPEG code

  function generate_thumbnail(name, path){
  
    logging.info("Generating Thumbnail");
  
    ffmpeg(path)
  
     .setFfmpegPath('/usr/bin/ffmpeg') 
  
     .setFfprobePath('/usr/bin/ffprobe')
  
     .on('end', function() {
  
          upload_thumbnail(name);
  
          logging.info("Thumbnail Generated and uploaded");
  
          return;
  
      })
  
    .on('error', function(err, stdout, stderr) {
  
          logging.info('ERROR: ' + err.message);
  
          logging.info('STDERR:' + stderr);
  
    })
  
    .on('start', function(commandLine) {
  
         logging.info(commandLine);
  
    })
  
    .screenshots({
  
      count: 1,
  
      filename: name + '_thumbnail.png',
  
      folder: 'public/images/thumbnails/'
  
    });
  
  }
