• Discord.js Music bot "TypeError" when playing audio with dispatcher

  21 février 2020, par Cole Perry

  I’m new to Discord.js and I’m trying to have the bot join a voice channel and play an audio file on my computer. I have been following this guide : https://discord.js.org/#/docs/main/stable/topics/voice . Here is the Index.js page :

  Colesbot.on('message', message=>{
  
      if (message.content === '/join') {
  
          // Only try to join the sender's voice channel if they are in one themselves
  
          if (message.member.voiceChannel) {
  
              message.member.voiceChannel.join().then(connection => {
  
                  message.reply('I have successfully connected to the channel!');
  
  
  
                  // To play a file, we need to give an absolute path to it
  
                  const dispatcher = connection.playFile('C:\Users\bobal\Documents\GitHub\Spotify-Playlist-Discord-bot\Assets\Glory.mp3');
  
  
  
                  dispatcher.on('end', () => {
  
                      // The song has finished
  
                      console.log('Finished playing!');
  
                    });
  
  
  
                  dispatcher.on('error', e => {
  
                      // Catch any errors that may arise
  
                      console.log(e);
  
                    });
  
  
  
                    dispatcher.setVolume(0.5); // Set the volume to 50%
  
              }).catch(console.log);
  
      } else {
  
          message.reply('You need to join a voice channel first!');
  
        }
  
      }
  
   });
  
  exports.run = (client, message, args) => {
  
      let user = message.mentions.users.first || message.author;
  
  }

  FFMPEG is installed and I have set the environment path for it. When I type FFMPEG in the command line I get the proper response.

  Some have said I need to install the ffmpeg binaries but when I run npm install ffmpeg-binaries I get an error message that is here

  So then I tried installing an older version and I’m now using ffmpeg-binaries@3.2.2-3 but when I type /join I get the error

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

• Ffmpeg "no directory found" when passing in a path to the mp3 file

  21 février 2020, par Eugene Levinson

  How my code should work :

  Join the voice channel with the user who sent the command

  Download the video using the link

  Save it as random 16 digit number .mp3

  Then pass the path to the FFmpeg player to play

  My code :

  The random 16 digit number

  def get_digits(amount):
  
      st = ""
  
      for i in range(amount):
  
          n = random.randint(0,9)
  
          st = st + str(n)
  
  
  
      return int(st)

  Downloading the file

  def get_path(url):
  
  
  
      #checking if the directory exists
  
      os.makedirs('Music', exist_ok=True)
  
  
  
      title = YouTube(url).streams.get_highest_resolution().title
  
      current_directory = pathlib.Path(__file__).parent.absolute()
  
  
  
      print(str(current_directory))
  
  
  
      #name for the music
  
      name = str(get_digits(16))
  
  
  
      YouTube(url).streams.filter(only_audio=True).order_by("bitrate").desc().first().download("Music",name )
  
      return str(str(current_directory) + "/Music/" + name + ".mp3")

  This gets called on command play

  #function to connect to a voice chat
  
  async def join_auth(ctx):
  
      try:
  
          channel = ctx.author.voice.channel
  
          vc = await channel.connect()
  
          return vc
  
      except Exception as e:
  
          logg("Exception occured when joining a voice channel: " + str(e),"error",str(ctx.guild.name), str(ctx.guild.id))

  The error I get :
  C:\Users\Eugene\Desktop\Discord bot/Music/4343941300524002.mp3: No such file or directory
  But the directory C:\Users\Eugene\Desktop\Discord bot\Music exists and it does contain the 4343941300524002.mp3 file. Does anyone know why do I get the error ?

• "Pixel format 'yuvj420p' is not supported" when converting image to video using CUDA hardware acceleration

  11 février 2020, par laurent

  I’m trying to convert an image to a video using CUDA hardware acceleration but I can’t get it to work.

  The basic command I have is this one :

  ffmpeg -y -hwaccel cuvid -i tests/MediaSamples/portrait_0.jpg -t 10 out.mp4

  And I’m getting this error :

  [AVHWFramesContext @ 0x32d3f00] Pixel format 'yuvj420p' is not supported
  
  [mjpeg @ 0x2d18480] Error initializing a CUDA frame pool
  
  cuvid hwaccel requested for input stream #0:0, but cannot be initialized.
  
  Error while decoding stream #0:0: Invalid argument

  I’ve tried setting the pixel format like so, but that didn’t help :

  ffmpeg -y -hwaccel cuvid -pix_fmt yuv420p -i tests/MediaSamples/portrait_0.jpg -t 10 out.mp4

  I’ve also tried many other flags but can’t get anything to work. Any idea what the issue might be ?
