• Discord bot python : discord.errors.ClientException : ffmpeg was not found

  14 septembre 2021, par S. Klore

  I'm trying to make a discord bot that plays music in a voice channel. It connects to the voice channel, but doesn't play anything. It also gives an error in the console.

  



  I'm on Windows and I'm using the discord.py rewrite.

  



  My code :

  



  import discord, random, datetime, asyncio, nacl, ffmpeg

TOKEN = 'What token'

client = discord.Client()

@client.event
async def on_message(message):
if message.content.lower() == '$play':
    if message.content.lower() == '$play':
        channel = client.get_channel(547155964328149007)
        vc = await channel.connect()
        vc.play(discord.FFmpegPCMAudio('mp3.mp3'), after=lambda e: print('done', e))
        vc.is_playing()
        vc.pause()
        vc.resume()
        vc.stop()

@client.event
async def on_ready():
    print('Logged in as {0.user}'.format(client))

client.run(TOKEN)


  



  The error :

  



  Traceback (most recent call last):
  File "D:\Python35\lib\site-packages\discord\client.py", line 218, in _run_event
    await coro(*args, **kwargs)
  File "discord_bot.py", line 90, in on_message
    vc.play(discord.FFmpegPCMAudio('mp3.mp3'), after=lambda e: print('done', e))
  File "D:\Python35\lib\site-packages\discord\player.py", line 165, in __init__
    raise ClientException(executable + ' was not found.') from None
discord.errors.ClientException: ffmpeg was not found.


  



  People seem to have a similar-ish issue with ffmpeg/avconv was not found in your PATH environment variable but the fix for them is to download ffmpeg from a website and put it in their PATH, but that doesn't work for me.

  



  Further more I can only find fixes for my problem in JavaScript, while I'm coding the bot in Python 3.

  



  Here are some links from my research :

  



  You need to add FFmpeg to your path

• A Soundboard for Discord with Discord.py with already downloaded .mp3 files

  8 août 2019, par Kerberos Kev

  I’m setting up a discord bot with discord.py, and want to implement an soundboard.The soundboard should take already downloaded .mp3 files and play them in the discord. The bot already automatically joins and disconnects from a voice channel but does not play any of my sound files.

  I tried converting the mp3 file into an opus one and just play it without ffmpeg but this didn’t work either.

  import discord
  
  from discord.ext import commands
  
  from discord.utils import get
  
  from mutagen.mp3 import MP3
  
  import time
  
  import os
  
  
  
  client = commands.Bot(command_prefix='<')
  
  a = './'+'kurz-kacken.mp3'
  
  
  
  
  
  class Soundboard(commands.Cog):
  
  
  
      def __init__(self, client):
  
          self.client = self
  
  
  
      @commands.command(pass_context=True)
  
      async def soundboard(self, ctx, songname: str):
  
          channel = ctx.message.author.voice.channel
  
          voice = get(client.voice_clients, guild=ctx.guild)
  
  
  
          if voice and voice.is_connected():
  
              await voice.move_to(channel)
  
          else:
  
              voice = await channel.connect()
  
  
  
              print(f"The bot has connected to {channel}\n")
  
  
  
          # audio = MP3('./'+'kurz-kacken.mp3')
  
          # a = audio.info.length
  
          voice.play(discord.FFmpegPCMAudio('./'+'kurz-kacken.mp3'),
  
                     after=lambda e: print("Song done!"))
  
          voice.source = discord.PCMVolumeTransformer(voice.source)
  
          voice.source.volume = 0.07
  
          # time.sleep(a)
  
          await ctx.send(f'ended')
  
  
  
          if voice and voice.is_connected():
  
              await voice.disconnect()
  
  
  
  
  
  def setup(client):
  
      client.add_cog(Soundboard(client))

  songs = asyncio.Queue(maxsize=0)
currently_playing = False


@client.command()
async def play(ctx, url):
    global songs
    global currently_playing
    if currently_playing:
        with yt_dlp.YoutubeDL({"format": "bestaudio", "outtmpl": "Queue_Download/%(title)s.%(ext)s"}) as ydl:
            info = ydl.extract_info(url, download=True)
            filename = ydl.prepare_filename(info)

async def queue(ctx):
    global songs
    global currently_playing
    currently_playing = True
    while True:
        if songs.empty():
            currently_playing = False
            await ctx.reply("Queue is now empty")
            await ctx.voice_client.disconnect()  # disconnect from voice channel when queue is empty
            break
        else:    
            song = await songs.get()
            filename = song["file"]
            voice_channel = ctx.author.voice.channel
            if not ctx.voice_client:  # check if bot is not already connected to a voice channel
                await voice_channel.connect()

            await ctx.reply('playing')
            await ctx.voice_client.play(discord.FFmpegPCMAudio(filename))

@client.command()
async def stop(ctx):
    global songs
    await ctx.voice_client.disconnect()
    await empty_queue(songs)
    await ctx.reply('Stopped')

async def empty_queue(songs):
    while not songs.empty():
        songs.get_nowait()


  


  I have problems with the "await ctx.voice_client.play(discord.FFmpegPCMAudio(filename))" which doesn't continue after finishing.

  


  I know you can use a after= parameter in voice_client.play() but I didn't manage to get it to work to recursivly call queue()

  


  async def play_next(ctx):
global songs
global currently_playing
if songs.empty():
    currently_playing = False
    await ctx.reply("Queue is now empty")
    await ctx.voice_client.disconnect()  # disconnect from voice channel when queue is empty
else:    
    song = await songs.get()
    filename = song["file"]
    voice_channel = ctx.author.voice.channel
    if not ctx.voice_client:  # check if bot is not already connected to a voice channel
        await voice_channel.connect()

    def after(error):
        if error:
            print(f'Error in after callback: {error}')
        asyncio.create_task(play_next(ctx))

    await ctx.reply('playing')
    ctx.voice_client.play(discord.FFmpegPCMAudio(filename), after=after)


  


  I tried using the after parameter like like but I just get an error in line 116, in after asyncio.create_task(play_next(ctx)) "no running event loop" ... "Calling the after function failed"

  


  EDIT

  


  async def play_next(ctx):
global loop
global songs
global currently_playing
global tasks
loop = asyncio.get_event_loop()
if songs.empty():
    currently_playing = False
    await ctx.reply("Queue is now empty")
    await ctx.voice_client.disconnect()  # disconnect from voice channel when queue is empty
else:
    
    song = await songs.get()
    filename = song["file"]
    voice_channel = ctx.author.voice.channel
    if not ctx.voice_client:  # check if bot is not already connected to a voice channel
        await voice_channel.connect()
    def after(error):
        if error:
            print("er")
        loop.create_task(queue(ctx))

    await ctx.reply('playing')
    ctx.voice_client.play(discord.FFmpegPCMAudio(filename), after=after)


  


  using loop = asyncio.get_event_loop() and loop.create_task(queue(ctx)) made it finally work
