• 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 (args.length !== 1) {
  
              message.channel.send("Play command takes 1 YouTube link.");
  
              reject("Wrong number of arguments");
  
              return;
  
          }
  
          const voiceChannel = message.member.voiceChannel;
  
          if(!voiceChannel) {
  
              message.channel.send("You need to connect to a voice channel first");
  
              reject("Not connected to voice channel");
  
              return;
  
          }
  
          const perms = voiceChannel.permissionsFor(message.client.user);
  
          if (!perms.has("CONNECT")) {
  
              message.channel.send("You need to add the 'connect' permission for this bot");
  
              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.py music bot doesn't play next song in queue

  10 mai 2019, par Lewis H

  This is my code for the bot I’m trying to create, it plays the music fine.

  ytdl_options = {
  
      'format': 'bestaudio/best',
  
      'restrictfilenames': True,
  
      'noplaylist': True,
  
      'nocheckcertificate': True,
  
      'quiet':True,
  
      'ignoreerrors': False,
  
      'logtostderr': False,
  
      'no_warnings': True,
  
      'default_search': 'auto',
  
      'source_address': '0.0.0.0' # using ipv4 since ipv6 addresses causes issues sometimes
  
      }
  
  
  
  
  
          # ffmpeg options
  
  ffmpeg_options= {
  
      'options': '-vn'
  
      }
  
  
  
  
  
  
  
  @bot.command()
  
  async def play(ctx, url:str = None): 
  
      queue = {} 
  
  
  
      channel = ctx.author.voice.channel    
  
      if ctx.voice_client is not None:  
  
          await ctx.voice_client.move_to(channel)
  
      elif ctx.author.voice and ctx.author.voice.channel:       
  
          await channel.connect()
  
  
  
      if not url:
  
          await ctx.send("Try adding a URL. e.g. !play https://youtube.com/watch?v=XXXXXXXXX")
  
  
  
      if ctx.voice_client is not None:
  
          vc = ctx.voice_client #vc = voice client, retrieving it
  
          ytdl = youtube_dl.YoutubeDL(ytdl_options)
  
  
  
  
  
          loop = asyncio.get_event_loop()
  
          data = await loop.run_in_executor(None, lambda: ytdl.extract_info(url))
  
  
  
          if 'entries' in data:
  
              data = data['entries'][0] 
  
          svr_id = ctx.guild.id
  
          if svr_id in queue:
  
              queue[svr_id].append(data)
  
  
  
          else:
  
              queue[svr_id] = [data]
  
          await ctx.send(data.get('title') + " added to queue")
  
  
  
          source = ytdl.prepare_filename(queue[svr_id][0])
  
          def pop_queue():
  
              if queue[svr_id] != []:
  
                  queue[svr_id].pop(0)
  
                  data = queue[svr_id][0]
  
              else:
  
                  vc.stop()
  
  
  
          if not vc.is_playing():
  
              vc.play(discord.FFmpegPCMAudio(source, **ffmpeg_options), after=lambda: pop_queue())

  The next song downloads and queues it fine, but once the first song finishes, it doesn’t play the next one. I can’t figure out how to make it play after the first song has commenced. I have the after= set to remove the top item of the queue, but how do I get it to play again ? Thanks

• My own music bot randomly stops when playing a song, no errors, just like the song has ended

  18 avril 2019, par Stasio

  I made a discord music bot but there is one problem :
  When i play something it works perfectly for a moment but then sometimes music ends in the middle of the song just like the song has ended.
  When there are some songs in queue and this bug happens the bot starts playing another song from the queue. Im using ffmpeg, ytdl-core, simple-youtube-api,
  opusscript. What do u guys think about it ? I don’t think that this problem is caused by my code cuz this error happens randomly, sometimes 3 songs in a row are played normaly and sometimes it crashes in the middle of the 1 song, so he starts playing the next song in queue.
