• 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

• Can you think of a reason why windows might not enable audio if noone is logged in ?

  3 juillet 2017, par Caius Jard

  I’m having a bizarre problem with some virtual servers created to record podcasts. They run on amazon AWS as windows server 2012 instances and a small c# app tells FFMPEG to do the heavy lifting of capturing from the virtual screen and reading from the virtual sound card (Virtual Audio Cable : https://en.wikipedia.org/wiki/Virtual_Audio_Cable) via DirectShow filters

  The problem I have is if I leave the machine to do its stuff unattended, the recordings are sometimes silent. If I log in via VNC and watch it doing its stuff the audio is recorded just fine. All other aspects of the test op are the same, and the virtual machine is shut down between successive recordings so each one should theoretically be a clean slate. The app runs under a logged in session (hence the use of VNC rather than RDP)

  I’m now wondering if there is some optimisation of the windows sound engine whereby it doesn’t bother playing audio if it thinks noone is listening. The confusing thing to me is that not every virtual machine suffers these problems ; some of them record fine (and they’re all created from the same seed virtual hard disk image) in unattended mode

  I’m asking this question with the aim of getting together a list of things I can check/look into/debug.. I don’t have much knowledge of how MME/DirectSound/WASAPI work internally...

• Transcode video with php ffmpeg library

  27 juin 2019, par dev

  I need to upload video in 3 formate/resolution as 360p, 480p, 720p.

  After some research i got to know that some paid service are there like Amazone Elastic Transcoder . But i want to do with open source so i found FFMPEG.

  Also i want to upload video on Amazon s3 after transcode and video are in big size like video may contain 1GB size.

  I got php library for FFMPEG Library Link

  I have installed ffmpeg and it successfully generate new video. But i cannot figure out that how can i generate different formate/resolution as 360p, 480p, 720p.

  My sample Code is

          error_reporting(E_ALL);
  
          ini_set('display_errors', 1);
  
  
  
          require 'vendor/autoload.php';
  
  
  
          //$ffmpeg = FFMpeg\FFMpeg::create();
  
          $video = $ffmpeg->open('assets/small.mp4');
  
          $video
  
              ->filters()
  
              ->resize(new FFMpeg\Coordinate\Dimension(320, 240))
  
              ->synchronize();
  
          $video
  
              ->frame(FFMpeg\Coordinate\TimeCode::fromSeconds(2))
  
              ->save('assets/frame.jpg');
  
  
  
          $format = new FFMpeg\Format\Video\X264();
  
          $format->setAudioCodec("libmp3lame");
  
  
  
          $video->save($format, 'assets/new.mp4');

  Can anyone suggest me any way that how can i achieve this ??
