• Why does it say error finding module when I already installed it

  13 mai 2020, par MiqhtieLol

  I am trying to code a discord music bot and this is my code :

  



  const config = require('config.json')
const Discord = require('discord.js');
const ffmpeg = require('ffmpeg-extra')
const client = new Discord.Client();

client.once('ready', () => {
    console.log('Ready!');
});
client.on('message', message => {
    if(message.content.toLocaleLowerCase() === "elevator"){
        if(message.member.voice.channel){
            message.channel.send("Thanks to https://www.bensound.com for supplying us with this music.")
            play(message.member.voice.channel)
        }
        else {
            message.channel.send("Yo, please join a VC first.")
        }
    }
});

async function play(voiceChannel) {
    const connection = await voiceChannel.join();
    connection.play('elevator.mp3');
}

client.login(config.token);


  



  For some reason even though I installed ffmpeg via npm install ffmpeg it says :

  



  Error: Cannot find module 'ffmpeg-extra'


  



  EDIT : When I use const ffmpeg = require("ffmpeg") I get this error :

  



  UnhandledPromiseRejectionWarning: Error: FFmpeg/avconv not found!

• Swift framework project with internal C module - Undefined symbols for architecture arm64

  29 mars 2020, par Phạm Phi Phúc

  I’m creating Swift framework project using FFmpeg module internally.

  Steps are :

  1. Download source of FFmpeg from official website.
  2. Build it by build script here : https://github.com/kewlbear/FFmpeg-iOS-build-script
  3. Copy built file to project
  4. Create file module.modulemap, it’s content is :

  module FFmpeg [system][extern_c] {
  
  
  
      header "include/libavcodec/avcodec.h"
  
      header "include/libavdevice/avdevice.h"
  
      header "include/libavfilter/avfilter.h"
  
      header "include/libavformat/avformat.h"
  
      header "include/libavutil/avutil.h"
  
      header "include/libswresample/swresample.h"
  
      header "include/libswscale/swscale.h"
  
  
  
      export *
  
  }

  Project tree is :

  

  5. Set Import paths for both project settings and target settings to
     $(SRCROOT)/MediaToolkit/Libraries/FFmpeg/**
  6. My source code is :

  import Foundation
  
  import FFmpeg
  
  
  
  public class MediaToolkit {
  
      public init(){}
  
  
  
      public func hello() {
  
          print("AVFMT_NOFILE: \(AVFMT_NOFILE)")
  
          avformat_network_init()
  
      }
  
  }

  When I build it, I received error

  Undefined symbols for architecture arm64:
  
    "_avformat_network_init", referenced from:
  
        MediaToolkit.MediaToolkit.hello(Swift.String) -> () in MediaToolkit.o
  
  ld: symbol(s) not found for architecture arm64
  
  clang: error: linker command failed with exit code 1 (use -v to see invocation)

  If I remove line avformat_network_init(), it will print AVFMT_NOFILE: 1
