• Converting a PCM file from Discord.js call to MP3 or WAV using ffmpeg in Node.js causes file deletion without saving it. How can I solve this issue ?

  28 mai 2023, par ItsChriss

  I am trying to convert a pcm file, which I get from a discord call into a mp3 or wav file.
I saw a example with ffmpeg :

  


  const ffmpeg = require('ffmpeg');

try {
  var process = new ffmpeg('path/to/pcm/file');
  process.then(function (audio) {
    audio.fnExtractSoundToMP3('path/to/new/file.mp3', function (error, file) {
      if (!error) console.log('Audio File: ' + file);
    });
  }, function (err) {
    console.log('Error: ' + err);      
  });
} catch (e) {
  console.log(e);
}


  


  But it's not saving or creating the file, it just deletes it without an error message. how can I fixx this ?

  


  I tried multiple methodes with other ffmpeg modules like "fluent-ffmpeg" but it didn't work eiter.

  


  This is the code I am using to get the PCM data :

  


  const reciever = connection.receiver.subscribe(message.author.id,
{             
  mode: "pcm",
  end: {                 
    behavior: EndBehaviorType.AfterSilence,                 
    duration: 1000             
  }         
})


  


• Output file not specified [closed]

  16 mai 2024, par Rich Madrid

  I have been messing around with ffmpeg working on basic mkv to mp4 conversions the last couple of days on my Mac and Windows computers. Mac was easier buy my windows desktop has a much faster OS so I wanted to do some conversions on it tonight. Got ffmpeg installed and working.

  


  After having some issues with the command prompt not finding the directory, I solved that with the following basic code to convert an mkv file to an mp4 for me :

  


  ffmpeg -i "C:\Users\Computer\videos\decade.mkv" "C:\Users\Computer\Videos\RJ videos\Complete\decade.mp4"


  


  I moved on to wanting to scale up an mkv to 1080p and use a yadif filter. I couldn’t find an adequate way to do this so I used a portion of the command that worked on my Mac last night, and stuffed it into the command for windows and I got an error code “at least one output file must be specified” after using the following command :

  


  ffmpeg -i "C:\Users\Computer\videos\decade.mkv" -vf "yadif=1,scale=1440x1080:flags=lanczos,setsar=1" -c:v libx264 -crf 21
-c:a aac -b:a 128k -ar 48k "C:\Users\Computer\Videos\RJ videos\Complete\decade.mp4"


  


  What am I doing wrong ?
