• 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

• "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 ?

  For information this is the full log :

• FFMPEG cannot encode .MP4 to usable .Y4M RAW video : "Operation not permitted"

  26 janvier 2020, par Ham789

  I am running ffmpeg version 4.2.2 on macOS Sierra and I cannot decode a RAW video.

  First I create the .Y4M video :

  ffmpeg -y -i inputfolder/GH012088.MP4 temp_raw_video.Y4M

  Then I try to input it to ffmpeg :

  ffmpeg -i temp_raw_video.Y4M 

  However I get the following error in the terminal : temp_raw_video.Y4M: Operation not permitted

  I have checked the permissions for the ’temp_raw_video.Y4M’ file and I have both read and write permissions.

  I have tried the above with .MOV videos from an iPhone and it works fine.

  The problem seems to be with the .MP4 videos I am trying to convert. These videos were taken with a GoPro camera.

  What is going on here ? Please see the GH012088.MP4 file info below :
