• Discord.js "Error : FFMPEG not found" but I'm pretty sure I have it

  21 février 2020, par Cole Perry

  I’m learning Discord.js and following this tutorial : https://discord.js.org/#/docs/main/stable/topics/voice . From the start, when I try to run- npm install ffmpeg-binaries I get a huge error message but it tells me to just use install ffmpeg so I did.

  Here is my Index.js page(I’ve replaced my token with * here) :

  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!');
  
              }).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;
  
  
  
  
  
  }

  If I type "/join" while not connected to a voice channel I get the proper message. However, if I try while I am I get this error message :

  Error: FFMPEG not found
  
  task_queues.js:94
  
  message:"FFMPEG not found"
  
  stack:"Error: FFMPEG not found\n    at Function.selectFfmpegCommand (c:\Users\bobal\Documents\GitHub\Spotify-Playlist-Discord-bot\node_modules\prism-media\src\transcoders\ffmpeg\Ffmpeg.js:46:13)\n    at new FfmpegTranscoder (c:\Users\bobal\Documents\GitHub\Spotify-Playlist-Discord-bot\node_modules\prism-media\src\transcoders\ffmpeg\Ffmpeg.js:7:37)\n    at new MediaTranscoder (c:\Users\bobal\Documents\GitHub\Spotify-Playlist-Discord-bot\node_modules\prism-media\src\transcoders\MediaTranscoder.js:10:19)\n    at new Prism (c:\Users\bobal\Documents\GitHub\Spotify-Playlist-Discord-bot\node_modules\prism-media\src\Prism.js:5:23)\n    at new VoiceConnection (c:\Users\bobal\Documents\GitHub\Spotify-Playlist-Discord-bot\node_modules\discord.js\src\client\voice\VoiceConnection.js:46:18)\n    at c:\Users\bobal\Documents\GitHub\Spotify-Playlist-Discord-bot\node_modules\discord.js\src\client\voice\ClientVoiceManager.js:63:22\n    at new Promise (<anonymous>)\n    at ClientVoiceManager.joinChannel (c:\Users\bobal\Documents\GitHub\Spotif...
  
  </anonymous>

  So I went to that folder and the file Ffmpeg.js is there and here is its contents :

  const ChildProcess = require('child_process');
  
  const FfmpegProcess = require('./FfmpegProcess');
  
  
  
  class FfmpegTranscoder {
  
    constructor(mediaTranscoder) {
  
      this.mediaTranscoder = mediaTranscoder;
  
      this.command = FfmpegTranscoder.selectFfmpegCommand();
  
      this.processes = [];
  
    }
  
  
  
    static verifyOptions(options) {
  
      if (!options) throw new Error('Options not provided!');
  
      if (!options.media) throw new Error('Media must be provided');
  
      if (!options.ffmpegArguments || !(options.ffmpegArguments instanceof Array)) {
  
        throw new Error('FFMPEG Arguments must be an array');
  
      }
  
      if (options.ffmpegArguments.includes('-i')) return options;
  
      if (typeof options.media === 'string') {
  
        options.ffmpegArguments = ['-i', `${options.media}`].concat(options.ffmpegArguments).concat(['pipe:1']);
  
      } else {
  
        options.ffmpegArguments = ['-i', '-'].concat(options.ffmpegArguments).concat(['pipe:1']);
  
      }
  
      return options;
  
    }
  
  
  
    /**
  
     * Transcodes an input using FFMPEG
  
     * @param {FfmpegTranscoderOptions} options the options to use
  
     * @returns {FfmpegProcess} the created FFMPEG process
  
     * @throws {FFMPEGOptionsError}
  
     */
  
    transcode(options) {
  
      if (!this.command) this.command = FfmpegTranscoder.selectFfmpegCommand();
  
      const proc = new FfmpegProcess(this, FfmpegTranscoder.verifyOptions(options));
  
      this.processes.push(proc);
  
      return proc;
  
    }
  
  
  
    static selectFfmpegCommand() {
  
      try {
  
        return require('ffmpeg-binaries');
  
      } catch (err) {
  
        for (const command of ['ffmpeg', 'avconv', './ffmpeg', './avconv']) {
  
          if (!ChildProcess.spawnSync(command, ['-h']).error) return command;
  
        }
  
        throw new Error('FFMPEG not found');
  
      }
  
    }
  
  }
  
  
  
  module.exports = FfmpegTranscoder;

  I also added ffmpeg to system path and it didn’t help :

  C:\ffmpeg
  
  C:\Users\bobal\Documents\GitHub\Spotify-Playlist-Discord-bot\ffmpeg

  I’m not quite sure what to do from here. If you need any other info I’d be glad to give it.

  Thanks in advance.

• In the using directive "using Accord.Video.FFMPEG", FFMPEG does not exist in the name space

  15 septembre 2019, par StewartMetcalfe

  I am building an Azure Function in Visual Studio to convert a videos frames to images. I’m using the VideoFileReader class from Accord.Video.FFMPEG class. The code works on my machine but when trying to build this as an Azure Function Project, the using directive Accord.Video.FFMPEG errors.
  And subsequently the type VideoFileReader can not be found.

  I have tried re-installing the Accord, Accord.Video and Accord.Video.FFMPEG NuGet packages.

  using System.IO;
  
  using Microsoft.Azure.WebJobs;
  
  using Microsoft.Extensions.Logging;
  
  using Accord;
  
  using Accord.Video;
  
  using Accord.Video.FFMPEG;
  
  
  
  namespace ConvertVideo
  
  {
  
      public static class Function1
  
      {
  
          [FunctionName("Function1")]
  
          public static void Run([BlobTrigger("videos/{name}", Connection = "AzureWebJobsStorage")]Stream myBlob, string name, ILogger log)
  
          {
  
              log.LogInformation($"C# Blob trigger function Processed blob\n Name:{name} \n Size: {myBlob.Length} Bytes");
  
  
  
              //start a new videoFileReader
  
              using (var vFReader = new VideoFileReader())
  
              {
  
                  //open the video
  
                  vFReader.Open(name);
  
                  //get the framerate
  
                  double frameRate = vFReader.FrameRate.ToDouble();
  
                  //more code which converts a frame to jpg
  
              }
  
          }   
  
      }
  
   }
