• Discord.js Music bot TypeError [ERR_INVALID_ARG_TYPE] : The "file" argument must be of type string. Received type object

  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 :

  const Discord = require('discord.js');
  
  const Colesbot = new Discord.Client();
  
  
  
  const token = '***********************************************';
  
  
  
  
  
  
  
  Colesbot.on('ready', () =>{
  
      console.log('Slamsbot is online.');
  
  })
  
  
  
  Colesbot.on('message', msg=>{
  
     if(msg.content == "What up bot?"){
  
         msg.reply("Whats good pimp?")
  
     }
  
  });
  
  
  
  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!');
  
        }
  
      }
  
   });
  
  
  
  
  
  
  
  //Event listener for new guild members
  
  Colesbot.on('guildMemberAdd', member =>{
  
      // Send the message to a designated channel on a server:
  
      const channel = member.guild.channels.find(ch => ch.name === 'general');
  
      // Do nothing if the channel wasn't found on this server
  
      if (!channel) return;
  
      // Send the message, mentioning the member
  
      channel.send(`Welcome to the server, ${member}. Please use the bot-commands channel to assign yourself a role.`);
  
  })
  
  
  
  Colesbot.login(token);
  
  
  
  
  
  
  
  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 this error message :

  npm WARN deprecated ffmpeg-binaries@4.0.0: ffmpeg-binaries is no longer being maintained. use ffmpeg-static, or just install ffmpeg

• Python & OpenCV - VideoCapture.read() always returns false

  21 août 2017, par Julen

  I need to extract frames from a video at a given time, and I’m using OpenCV for it. I’m using Linux Mint 18.1, but it must also run on Ubuntu.

  This code example is not working for me :

  import cv2
  
  
  
  print('making screenshot from {0}'.format('/tmp/big_buck_bunny_720p_5mb.mp4'))
  
  
  
  cap = cv2.VideoCapture(video_path)
  
  cap.set(cv2.CAP_PROP_POS_MSEC,1000)
  
  ret,frame = cap.read()
  
  print(ret)                      # This is false
  
  cv2.imwrite("image.jpg", frame) # Creates an empty file

  (I’ve checked that the path of the video is correct and that the file is not corrupted).

  I have installed the Python OpenCV 3.3.0 version :

  >>> import cv2
  
  >>> cv2.__version__
  
  '3.3.0'

  I’ve compiled and installed the source for OpenCV (with the WITH_FFMPEG=ON option) :

• Django api returns Gif as JPG despite a function to add it as video

  7 septembre 2023, par Earthling

  I'm trying to upload a .gif to my django 3.2 api. I have already ran troubleshoots through Postman and came to the conclusion that my flutter app sends it as a .gif and it gets returned as a .jpg. The problem is on the backend. Here is my relevant code which checks for file_meme subtype and then the function should convert the incoming .gif to a video :

  


  


  


  def add_media(self, file, order=None):
    check_can_add_media(post=self)

    is_in_memory_file = isinstance(file, InMemoryUploadedFile) or isinstance(file, SimpleUploadedFile)

    if is_in_memory_file:
        file_mime = magic.from_buffer(file.read())
    elif isinstance(file, TemporaryUploadedFile):
        file_mime = magic.from_file(file.temporary_file_path())
    else:
        file_mime = magic.from_file(file.name)

    check_mimetype_is_supported_media_mimetypes(file_mime)
    # Mime check moved pointer
    file.seek(0)

    file_mime_types = file_mime.split('/')

    file_mime_type = file_mime_types[0]
    file_mime_subtype = file_mime_types[1]

    temp_files_to_close = []

    if file_mime_subtype == 'gif':
                if is_in_memory_file:
                    file = write_in_memory_file_to_disk(file)

                temp_dir = tempfile.gettempdir()
                converted_gif_file_name = os.path.join(temp_dir, str(uuid.uuid4()) + '.mp4')

                ff = ffmpy.FFmpeg(
                    inputs={file.temporary_file_path() if hasattr(file, 'temporary_file_path') else file.name: None},
                    outputs={converted_gif_file_name: None})
                ff.run()
                converted_gif_file = open(converted_gif_file_name, 'rb')
