• 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.

  const arg = msg.content.split(' ');
  
  const searchString = arg.slice(1).join(' ');
  
  const url = arg[1] ? arg[1].replace(/<(.+)>/g, '$1') : '';
  
  const serverQueue = queue.get(msg.guild.id);
  
  
  
  let command = msg.content.toLowerCase().split(' ')[0];
  
  command = command.slice(PREFIX.length)
  
  
  
  if (command === 'play' || command === 'p') {
  
  msg.delete()
  
  const voiceChannel = msg.member.voiceChannel;
  
  let emoji = msg.guild.emojis.find(x => x.name === "2Head")
  
      if (!voiceChannel) return msg.channel.send('Nie jesteś nawet na kanale głosowym zjebie ' + emoji);
  
      const permissions = voiceChannel.permissionsFor(msg.client.user);
  
      if (!permissions.has('CONNECT')) {
  
          return msg.channel.send('Nie mam permisji zeby sie polaczyc ;/');
  
      }
  
      if (!permissions.has('SPEAK')) {
  
          return msg.channel.send('Nie moge mowic odmutujcie mnie : )');
  
      }
  
  
  
      if (url.match(/^https?:\/\/(www.youtube.com|youtube.com)\/playlist(.*)$/)) {
  
          const playlist = await youtube.getPlaylist(url);
  
          const videos = await playlist.getVideos();
  
          for (const video of Object.values(videos)) {
  
              const video2 = await youtube.getVideoByID(video.id); 
  
              await handleVideo(video2, msg, voiceChannel, true); 
  
          }
  
          return msg.channel.send(`✅ Playlist: **${playlist.title}** has been added to the queue!`);
  
      } else {
  
          try {
  
              var video = await youtube.getVideo(url);
  
          } catch (error) {
  
              try {
  
                  var videos = await youtube.searchVideos(searchString, 1);
  
                  var video = await youtube.getVideoByID(videos[0].id);
  
              } catch (err) {
  
        console.error(err);
  
        let emoji = msg.guild.emojis.find(x => x.name === "autism")
  
                  return msg.channel.send('Nie ma takiego filmu na całym youtubie ' + emoji );

• Small discord bot with a set of working music commands, about 6 days ago the play function completely stopped functioning (more below)

  24 février 2021, par TheColoradoKid

  It is a small discord python bot for my server with various features, which had included music commands until they stopped out of the blue without showing any error for the problem.
It uses FFMpeg, and youtubeDl along with pytube to gather the song and store it locally to play it, I have pip updated all of these and they are definitely on the current versions as I have made sure of this online.
Any help or insight anyone could provide would be greatly appreciated. I'm sorry if the code is convoluted in the way it's written I'm still pretty new to coding and this is one of my first proper larger projects.

  


  If you need any information I'm happy to give what I can to help.

  


  Here is the code for the play command :

  


  @client.command()
async def play(ctx, *args):
    global queu
    #global autom
    if not args:
        voice = get(client.voice_clients, guild=ctx.guild)
        if not voice.is_playing():
            server = ctx.message.guild
            voice_channel = server.voice_client
            if queu:
                async with ctx.typing():
                    player = await YTDLSource.from_url(queu[0], loop=client.loop)
                    voice_channel.play(player, after=lambda e: print('Player error: %s' % e) if e else None)

                await ctx.send('**Now playing:** {}'.format(player.title))
                del(queu[0])
                # while autom == True:
                #     try:
                #         a = client.get_command('auto')
                #         await ctx.invoke(a)
                #     except:
                #         print('')
            elif not queu:
                await ctx.send("You can't play if there isn't anything in the queue\nIf auto mode was on it has now been disabled, to use it gain please add to the queue and run ``;auto on``")
                autom = False
    if args:
        global gueu
        search_keywords = ""
        print(args)
        for word in args:
            search_keywords += word
            search_keywords += '+'
        link = "https://www.youtube.com/results?search_query="
        link += search_keywords
        #print(link)
        html = urllib.request.urlopen(link)
        video_ids = re.findall(r"watch\?v=(\S{11})", html.read().decode())
        url = ("https://www.youtube.com/watch?v=" + video_ids[0])
        #print(url)
        queu.append(url)
        #print(queu)
        await ctx.send("``{}`` added to queue!\n If the song doesn't start please either let the current song end and run ``;play``/``;next`` again or run ``;next`` to play now".format(url))
        try:
            p = client.get_command('play')
            await ctx.invoke(p)
        except:
            print('failed')

  I guess the problem is something with ffmpeg or i must have some npms more.

  


  npm i already installed

  


  

  • discord.js

  


  • ytdl-core

  


  • ytdl-search
and also i already installed ffmpeg in my computer and set the path

  


  


  i want to ask that do i have to install any npms more ? or anyone know how to fixed this problem ?
