• Discord.py bot joins voice channel but when using voicechannel.play i get error:Command raised an exception : ClientException : Not connected to voice

  25 mai 2023, par AudibleDruid

  So i've managed to get my discord bot to join a voice channel but when i use the play command it gives me an error that its not conencted to voice Command raised an exception: ClientException: Not connected to voice.

  


  Here is my code :

  


  import discord
import random
import glob
from discord.ext import commands

##discord intents 
intents = discord.Intents()
intents.members = True
intents.messages = True
intents.guilds = True
intents.voice_states = True


  


  connect the bot to a voice channel :

  


      
##called when user wants bot to join voice channel
@bot.command(name ='join', help = 'Make the bot join a voice channel')
async def join(context):
    
    botVoice = context.message.guild.voice_client
    if context.guild.voice_client:
        botvoicechannel = context.message.guild.voice_client.channel
    else:
        botvoicechannel = None
    authorVoice = context.author.voice
    if context.author.voice:
        authorvoicechannel = context.author.voice.channel
    else:
        authorvoicechannel = None
    
    ##await context.reply('bot voice channel: {}\n\nbot voice:\n{}\n\nauthor voice channel: {}\n\nauthor voice voice:\n{}\n\n'.format(botvoicechannel, botVoice, authorvoicechannel, authorVoice))
    
    if not authorVoice and not botVoice:
        await context.reply('Connect to a voice channel first.')
        return
    elif authorVoice and not botVoice:
        await context.reply('Connecting to {}'.format(authorvoicechannel))
        await authorvoicechannel.connect()
        return
    elif not authorVoice and botVoice:
        await context.reply("You aren't in a channel, I'm in {}".format(botvoicechannel))
        return
    elif authorVoice and botVoice:
        if (botvoicechannel == authorvoicechannel):
            await context.reply("I'm already in here.")
            return
        else:
            await context.reply('Moving to you!')
            await botVoice.move_to(authorvoicechannel)
            return
        return


  


  and have it play a url :

  


  @bot.command(name ='play', help = 'Make the bot play a url')
async def play(context, url):
    botVoice = context.message.guild.voice_client
    audioSource = discord.FFmpegPCMAudio(url, executable="ffmpeg")
    botVoice.play(audioSource, after = None)


  


  the code works and the bot joins the voice channel. i see it in the voice channel with me, however i get an error when it gets to botVoice.play(audioSource, after = None)

  


  the error message is :
error: Command raised an exception: ClientException: Not connected to voice.

  


  i changed botVoice = context.message.guild.voice_client from botVoice = context.guild.voice_client but that didnt seem to change anything. not sure what to try next. It seems like it wants to play the url the bot just doesnt realize its in the voice channel with me.

  


  maybe a related error. if i kill my python script the bot remains in the channel even though its not running. then when i start it up and do the !join command it says its joining even though its already in the channel with me. its weird because on the join command it checks to see if its already in a voice channel so it should know that its in there with me. idk what to try next. thanks for any suggestions. i only posted relevant code. let me know if you think im missing something else.

  


  thanks for the help

  


• Can ffmpeg write metadata encoder when transcoding alac/flac to aac audio file ?

  11 juin 2022, par David I

  I have a collection of alac and flac files from Bandcamp and an ffmpeg instance compiled with libfdk_aac https://trac.ffmpeg.org/wiki/CompilationGuide/Centos#libfdk_aac and am trying to convert these to lossy audio aac files for non-critical listening.

  


  With ffmpeg -i Liholesie\ -\ Shamanic\ Twilight\ -\ 09\ Gray\ Wings.m4a -c:a libfdk_aac -vbr 4 -c:v copy 09_Gray_wings_vbr4.m4a an expected aac .m4a audio file is produced, album art included, works well. There's one slight detail missing :

  


  During the ffmpeg conversion process ffmpeg says :

  


  Output #0, ipod, to '09_Gray_wings_vbr4.m4a':
  Metadata:
    major_brand     : M4A 
    minor_version   : 512
    compatible_brands: M4A isomiso2
    title           : Gray Wings
    artist          : Liholesie
    album_artist    : Liholesie
    album           : Shamanic Twilight
    comment         : Visit https://liholesie.bandcamp.com
    date            : 2021
    track           : 9
    encoder         : Lavf59.24.100
  Stream #0:0: Video: mjpeg (Baseline), yuvj444p(pc, bt470bg/unknown/unknown), 700x700 [SAR 72:72 DAR 1:1], q=2-31, 90k tbr, 90k tbn (attached pic)
  Stream #0:1(und): Audio: aac (mp4a / 0x6134706D), 44100 Hz, stereo, s16 (default)
    Metadata:
      handler_name    : SoundHandler
      vendor_id       : [0][0][0][0]
      encoder         : Lavc59.33.100 libfdk_aac 
..




  


  and the file produced looks like that when ffprobed except that the Metadata : encoder field is missing :

  


  Input #0, mov,mp4,m4a,3gp,3g2,mj2, from '09_Gray_wings_vbr4.m4a':
  Metadata:
    major_brand     : M4A 
    minor_version   : 512
    compatible_brands: M4A isomiso2
    title           : Gray Wings
    artist          : Liholesie
    album_artist    : Liholesie
    album           : Shamanic Twilight
    date            : 2021
    encoder         : Lavf59.24.100
    comment         : Visit https://liholesie.bandcamp.com
    track           : 9
  Duration: 00:06:57.78, start: 0.000000, bitrate: 155 kb/s
  Stream #0:0[0x2](und): Audio: aac (LC) (mp4a / 0x6134706D), 44100 Hz, stereo, fltp, 152 kb/s (default)
    Metadata:
      handler_name    : SoundHandler
      vendor_id       : [0][0][0][0]
  Stream #0:1[0x0]: Video: mjpeg (Baseline), yuvj444p(pc, bt470bg/unknown/unknown), 700x700 [SAR 72:72 DAR 1:1], 90k tbr, 90k tbn (attached pic)


  


  Is there a way to write the encoder field in the Metadata section when transcoding (or is "encoder" not supported for aac m4a ? That would be weird since ffmpeg says what it says when specifying output during transcoding) .

  


  Any hints on how to write a self-defined text to said tag during transcoding are also welcome.

  


• Strange error with ffmpeg and unoconv in python script

  27 mai 2015, par Avery Ripoll Crocker

  I am creating a python script that can be used by other people to convert files. However when I use this script I keep getting a weird error when I run the subprocess for unoconv, this error is :

  Traceback (most recent call last):
  
    File "conversion.py", line 15, in <module>
  
      check_call(["unoconv", "-f", Fileextension, filename])
  
    File "/usr/lib/python2.7/subprocess.py", line 540, in check_call
  
      raise CalledProcessError(retcode, cmd)
  
  subprocess.CalledProcessError: Command '['unoconv', '-f', '.pdf', 'journal.doc']' returned non-zero exit status 1
  
  </module>

  I have looked through various resources for this, but the one answer I have been receiving is that I must have set up the unoconv line incorrectly. I have checked several times that the code is correct, and it is. The other peculiar thing is that my code for ffmpeg works. Does anybody have an idea as to why this happens.

  Here is my program :

  print "If at any point you wish to quit the program hit Ctrl + C"
  
  
  
  filetype = raw_input("What kind of file would you like to convert? Audio, Image, Video or Document: ")
  
  
  
  if filetype == "Document":
  
     path = raw_input("Please drag and drop the directory in which the file is stored into the terminal:")
  
     os.chdir(path[1:-2])
  
     filename = raw_input("Please enter the name of the file you would like to convert, including the file-type. e.g. test.txt, however please do make sure that the file-name does not have any spaces:")
  
     Fileextension = raw_input("What filetype would you like the program to convert your file to. E.g. .txt: ")
  
     from subprocess import check_call
  
     check_call(["unoconv", "-f", Fileextension, filename])
  
  
  
  elif filetype == "Audio":
  
     path = raw_input("Please drag and drop the directory in which the file is stored into the terminal:")
  
     os.chdir(path[1:-2])
  
     filename = raw_input("Please enter the name of the file you would like to convert, including the file-type. e.g. test.txt, however please do make sure that the file-name does not have any spaces:")
  
     Fileextension = raw_input("What filetype would you like the program to convert your file to. E.g. .mp3: ")
  
     body, ext = os.path.splitext("filename")
  
     from subprocess import check_call
  
     check_call(["ffmpeg" ,"-i", filename, body + Fileextension])
  
  
  
  elif filetype == "Video":
  
     path = raw_input("Please drag and drop the directory in which the file is stored into the terminal:")
  
     os.chdir(path[1:-2])
  
     filename = raw_input("Please enter the name of the file you would like to convert, including the file-type. e.g. test.txt, however please do make sure that the file-name does not have any spaces:")
  
     Fileextension = raw_input("What filetype would you like the program to convert your file to. E.g. .mp4: ")
  
     body, ext = os.path.splitext("filename")
  
     from subprocess import check_call
  
     check_call(["ffmpeg" ,"-i", filename, body + Fileextension])
  
  
  
  elif filetype == "Image":
  
     path = raw_input("Please drag and drop the directory in which the file is stored into the terminal:")
  
     os.chdir(path[1:-2])
  
     filename = raw_input("Please enter the name of the file you would like to convert, including the file-type. e.g. test.txt, however please do make sure that the file-name does not have any spaces:")
  
     Fileextension = raw_input("What filetype would you like the program to convert your file to. E.g. .Jpeg: ")
  
     body, ext = os.path.splitext("filename")
  
     from subprocess import check_call    
  
     check_call(["ffmpeg" ,"-i", filename, body + Fileextension])
