• Discord.js music bot : TypeError : this.inputMedia.pipe is not a function

  7 août 2019, par Ivs

  I’m writing a music Discord bot using Discord.js. The bot uses ytdl-core, node-opus, and I have installed ffmpeg on my OS (Ubuntu 19.04). When I try to make the bot join a voice channel and start playing a YouTube URL, it throws the following error :

  TypeError: this.inputMedia.pipe is not a function

          if (!perms.has("CONNECT")) {

              reject("NO CONNECT PERMISSION");
  
              return;
  
          }
  
          if (!perms.has("SPEAK")) {
  
              message.channel.send("You need to add the 'speak' permission for this bot");
  
              reject("NO SPEAK PERMISSION");
  
              return;
  
          }
  
          const streamOptions = { seek: 0, volume: 1, passes: 2 };
  
          voiceChannel.join()
  
              .then(connection => {
  
                  const stream = ytdl(args[0], {filter: 'audioonly'});
  
                  const dispatcher = connection.playStream(ytdl, streamOptions);
  
                  dispatcher.on("end", reason => {
  
                      console.log("reason: " + reason);
  
                      voiceChannel.leave();
  
                  })
  
                  dispatcher.on("error", err => {
  
                      console.log(err);
  
                  })
  
              })
  
          .catch(err => console.log(err));
  
      });    
  
  }

  I have tried reinstalling ffmpeg, node and npm, discord.js and node-opus. I have the newest version of Discord.js installed, and ffmpeg version 4.1.3-0ubuntu1. Anyone have any suggestions ?

  Thanks.

• Discord.js : How to play music stream from http?

  28 septembre 2019, par Maxim.Z

  This is my code :

  if (msg.content.includes('*stream')) {
  
          var name=(msg.content).slice(8,80);
  
      if (msg.member.voiceChannel) {
  
        msg.member.voiceChannel.join()
  
          .then(connection => {
  
                  console.log(name);
  
                    const dispatcher = connection.playFile(name);
  
                  dispatcher.setVolume(0.5); 
  
          })
  
          .catch(console.log);
  
      } else {
  
        msg.reply('Enter channel first');
  
      }
  
    }

  When I write in Discord *stream https://play.sas-media.ru/play, the console shows the full link (https://play.sas-media.ru/play), the bot enters the voice channel, but nothing else happens.

  What am I doing wrong ?

• Issues with Discord JS Music Bot

  5 décembre 2020, par Thresio

  I am in the process of creating a Discord bot with JS, giving it management, auto role, etc. I just got to the music section of it and I can't quite figure out whats wrong.

  



  I believe I have installed FFmpeg correctly, as I have access to it from within the terminal. I have also used npm to bring ytdl-core and opusscript into my program.

  



  What this should do is make the bot join the chat, then play the Youtube link. Currently, I am not error checking the second argument as I just wanted to get it working initially. I have implemented several different instances of .toString() and String() however it always gives the same error listed below.

  



  . The program still throws this error :

  



  TypeError [ERR_INVALID_ARG_TYPE]: The "file" argument must be of type string. Received type object

  Here is my code for calling play :

  



  case 'play':

            function play(connection, message){
                var server = servers[message.guild.id];

                server.dispatcher = connection.playStream(ytdl(server.queue[0], {filter: 'audioonly'}));

                server.queue.shift();

                server.dispatcher.on('end', function(){
                    if(server.queue[0]){
                        play(connection, message);
                    }else {
                        connection.disconnect();
                    }
                })
            }

            if(!args[1]){
                message.channel.send('You need to provide a link!');
                return;
            }

            if(!message.member.voiceChannel){
                message.channel.send('You must be in a voice channel to play music!');
                return;
            }

            if(!servers[message.guild.id]) servers[message.guild.id] = {
                queue: []
            }

            var server = servers[message.guild.id];

            server.queue.push(args[1]);

            if(!message.guild.voiceConnection) message.member.voiceChannel.join().then(function(connection){
                play(connection, message);
            })
            break;


  



  If anyone could assist with this, I would be very grateful.

  



  EDIT : I unfortunately never figured out my main issue, but I have now found code that works (unlike mine :/).
For anyone else having this issue, I suggest using the code found here.
Works like a charm !
