• 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             
  }         
})


  


• How to add multiple cookies using -cookies arugment in FFMPEG ?

  11 mai 2020, par Mercado

  I can add a single cookie in ffmpeg by using -cookies 'key=vale; path=/'. The debug log will then show the cookie in the final request header. However, I have no idea how to embed multiple cookies. The documentation says I can use \n to specify multiple cookies, but there is no example. I know I can use -headers but when I use '-header' I get "overlong headers".

  



  Any help ?

  


• is it necessary in Anaconda for Matplotlib to install ffmpeg for animation saving ?

  2 mai 2018, par Vasyl Kolomiets

  For animation saving I have read some propositions
  1) manual installing ffmpeg this way :

    conda install -c conda-forge ffmpeg

  2) manual installing ImageMagick and changing matplotlib configuration file "matplotlibrc" this way :

  #animation.ffmpeg_args: ''         # Additional arguments to pass to ffmpeg
  
  #animation.avconv_path: 'avconv'   # Path to avconv binary. Without full path
  
                                     # $PATH is searched
  
  #animation.avconv_args: ''         # Additional arguments to pass to avconv
  
  #animation.mencoder_path: 'mencoder'
  
                                     # Path to mencoder binary. Without full path
  
                                     # $PATH is searched
  
  #animation.mencoder_args: ''       # Additional arguments to pass to mencoder
  
  #animation.convert_path: 'convert' # Path to ImageMagick's convert binary.
  
  animation.convert_path: F:\Games\ImageMagick-7.0.7-Q16\magick.exe
  
                                     # On Windows use the full path since convert
  
                                     # is also the name of a system tool.

  where line with pass to installed ImageMagick was added manually

  animation.convert_path: F:\Games\ImageMagick-7.0.7-Q16\magick.exe

  Two questions :
  1 - what way is better for Anaconda ?
  2 - really Anaconda has no better way ????
