• ffmpeg mutliple file convert with error log file

  27 mars 2015, par ketan

  I am using ffmpeg for converting file from MKV to MP4.
  There is multiple video files like hundreds of files.

  I am using following command to convert file. I am using windows command line(cmd).

  ffmpeg -y -i "mkvfilename.mkv" -vcodec copy -acodec copy "mp4filename.mp4"

  It convert fine, But it become headache to convert hundred of files one by one.
  So, i like to create script for converting multiple file one by one.

  But there is some issue that there is some file are corrupted/damaged which are not converting. So, i need file name with path of that no converted Or error file.

  Is it possible in ffmpeg to get error file name which are not converted.
  Thanks,

• 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             
  }         
})
