• FFMPEG not found because FFMPEG-binaries is no longer supported

  17 novembre 2019, par brenan patrick

  I have been attempting to create a Discord bot, but it cannot connect to a voice channel because it gives the errorError: FFMPEG not found. Is there a way to get around using FFMPEG-binaries or an older version that I can install manually ?

  const Discord = require('discord.js');
  
  const {
  
          prefix,
  
          token,
  
  } = require('./config.json');
  
  const ytdl = require('ytdl-core');
  
  
  
  const client = new Discord.Client();
  
  
  
  const queue = new Map();
  
  
  
  client.once('ready', () => {
  
          console.log('Ready!');
  
  });
  
  
  
  client.once('reconnecting', () => {
  
          console.log('Reconnecting!');
  
  });
  
  
  
  client.once('disconnect', () => {
  
          console.log('Disconnect!');
  
  });
  
  
  
  client.on('message', async message => {
  
          if (message.author.bot) return;
  
          if (!message.content.startsWith(prefix)) return;
  
  
  
          const serverQueue = queue.get(message.guild.id);
  
  
  
          if (message.content.startsWith(`${prefix}play`)) {
  
                  execute(message, serverQueue);
  
                  return;
  
          } else if (message.content.startsWith(`${prefix}skip`)) {
  
                  skip(message, serverQueue);
  
                  return;
  
          } else if (message.content.startsWith(`${prefix}stop`)) {
  
                  stop(message, serverQueue);
  
                  return;
  
          } else {
  
                  message.channel.send('You need to enter a valid command!')
  
          }
  
  });

          const args = message.content.split(' ');

          if (!permissions.has('CONNECT') || !permissions.has('SPEAK')) {
  
                  return message.channel.send('I need the permissions to join and speak in your voice channel!');
  
          }
  
  
  
          const songInfo = await ytdl.getInfo(args[1]);
  
          const song = {
  
                  title: songInfo.title,
  
                  url: songInfo.video_url,
  
          };
  
  
  
          if (!serverQueue) {
  
                  const queueContruct = {

          serverQueue.connection.dispatcher.end();
  
  }
  
  
  
  function stop(message, serverQueue) {
  
          if (!message.member.voiceChannel) return message.channel.send('You have to be in a voice channel to stop the music!');
  
          serverQueue.songs = [];
  
          serverQueue.connection.dispatcher.end();
  
  }
  
  
  
  function play(guild, song) {
  
          const serverQueue = queue.get(guild.id);
  
  
  
          if (!song) {
  
                  serverQueue.voiceChannel.leave();
  
                  queue.delete(guild.id);
  
                  return;
  
          }
  
  
  
          const dispatcher = serverQueue.connection.playStream(ytdl(song.url))
  
                  .on('end', () => {
  
                          console.log('Music ended!');
  
                          serverQueue.songs.shift();
  
                          play(guild, serverQueue.songs[0]);
  
                  })
  
                  .on('error', error => {
  
                          console.error(error);
  
                  });
  
          dispatcher.setVolumeLogarithmic(serverQueue.volume / 5);
  
  }
  
  
  
  client.login(token);

  This is the error that appears after I attempt to ’ !play ’.

• nw.js node WebKit - unable to play audio file

  9 novembre 2018, par Allasso

  I have started working with nw.js, creating a test app to play audio files from. I am working on OS X 10.11.

  The code for the player is :

  <audio controls="controls">
  
    <source src="path/to/file/song.mp3" type="audio/mp3">
  
  </source></audio>

  The player and controls appear, but the file will not play. I have tried using a relative path, and an absolute path, trying both
  "/path/to/file/song.mp3"
  and
  "file :///path/to/file/song.mp3"
  schemes.

  I have verified the path is valid in all cases.

  This page :

  http://docs.nwjs.io/en/latest/For%20Developers/Enable%20Proprietary%20Codecs/

  tells me that mp3 should be supported (for v0.22.1+, though I haven’t found a way to tell the version of my mp3, though is was made recently so I assume is the the latest codec.)

  Just to try more stuff, I followed the instructions on these pages :

  http://docs.nwjs.io/en/latest/For%20Developers/Enable%20Proprietary%20Codecs/
  (It appears mp3 gained support since this doc came out.)

  https://github.com/nwjs/nw.js/wiki/Using-MP3-%26-MP4-%28H.264%29-using-the—video—%26—audio—tags.

  I downloaded the ffmpeg libs from here :

  https://github.com/iteufel/nwjs-ffmpeg-prebuilt/releases

  and placed copies here :

  find . -name libffmpeg.dylib
  
  ./dist/nw.js-examples/osx64/nw.js-examples.app/Contents/Versions/67.0.3396.87/libffmpeg.dylib
  
  ./node_modules/nw/nwjs/nwjs.app/Contents/Versions/54.0.2840.99/nwjs Framework.framework/libffmpeg.dylib
  
  ./node_modules/nw-builder/cache/0.31.2-sdk/osx64/nwjs.app/Contents/Versions/67.0.3396.87/libffmpeg.dylib
  
  cp ~/Downloads/libffmpeg.dylib ./dist/nw.js-examples/osx64/nw.js-examples.app/Contents/Versions/67.0.3396.87/libffmpeg.dylib
  
  cp ~/Downloads/libffmpeg.dylib "./node_modules/nw/nwjs/nwjs.app/Contents/Versions/54.0.2840.99/nwjs Framework.framework/libffmpeg.dylib"
  
  cp ~/Downloads/libffmpeg.dylib "./node_modules/nw-builder/cache/0.31.2-sdk/osx64/nwjs.app/Contents/Versions/67.0.3396.87/libffmpeg.dylib"

  Still to no avail running either

  npm run dev

  or

  npm run prod

  and opening the packaged app.

  I can play the file fine with the same code from a web browser.

  I don’t know what else to try, help would be much appreciated, thanks.

• Python pydub issue : Can't repoen a wav file after it as been reencoded by ffpeg [Silved]

  28 avril 2024, par Trent Tompkins

  Solved by Michael Butscher. Updated code is now in the repo in the fixed branch. Thanks !

  


  I have a python script that reads in all the *.wav files in a directory and saves them in a folder called output after it adjusts their volume.

  


  lower.py :

  


  import os
from pydub import AudioSegment as ass

# get the current working directory
current_working_directory = os.getcwd()
all_files = os.listdir();

 


while len(all_files) > 0:
    file = all_files.pop()
    song = ass.from_wav(file)
    song = song - 16
    song.export('out\\'+file)



  


  https://github.com/tibberous/ChangeWavVolume/tree/fixed

  


  The problem is (and this took me a LONG time to figure out), after the files are output once, if you try to read them again with AudioSegment ::from_wav(file), ffmpeg throws an error saying it can't decode the file. The output wav files play in Windows Media Player, and even have their audio adjusted, but I am guessing there somehow an error either in the file data itself or the file headers.

  


  I put the code on github. Checkout the branch 'fixed'.

  


  Btw, I just installed everything, so I should have the current versions of everything. I am using the Chocolatey package manager for Windows 10. Read README.txt (in progress) to see how I setup my dev environment.

  I opened the wav files the program generated with Media Player, VLC Media Player and Audacity, thinking they might throw an error, but the only thing that can't seem to read the exported wav files is the script that created them !
