• Promise chaining and resolution

  23 janvier 2019, par Shourya Sharma

  I am trying to convert videos one by one with the help of promises. i am using ffmpeg for conversion and multer for uploading multiple files.

  multer uploads multiple files at once after which i have to chain the conversions one by one. as of now it just converts the 1st file.

  i thought chaining of promises ..like in an array should work but i am confused if i can define new promises in an array as ffmpeg also returns a promise

  My router :

  const router = require('express').Router();
  
  const multer = require('multer');
  
  const ffmpeg = require('ffmpeg');
  
  
  
  let str;
  
  const storage = multer.diskStorage({
  
    destination: (req, file, cb) => {
  
      cb(null, './uploads');
  
    },
  
    filename: (req, file, cb) => {
  
      str = file.originalname.replace(/\.[^/.]+$/, "");
  
      str = str.replace(/[^a-z0-9+]+/gi, '_') + '.' + file.originalname.replace(/^.*\./, '');
  
      cb(null, str);
  
    }
  
  });
  
  
  
  const upload = multer({ storage: storage }).array('files', 12);
  
  
  
  router.post('/upload', (req, res, next) => {
  
    // req.files is an array of files
  
    // req.body will contain the text fields, if there were any
  
    function uploadFile() {
  
      return new Promise((resolve, reject) => {
  
        upload(req, res, (err) => {
  
          if (err) {
  
            res.send(err) // Pass errors to Express.
  
            reject(`Error: Something went wrong!`);
  
          } else if (req.files == undefined) {
  
            res.send(`No File selected.`);
  
            resolve();
  
          } else if (!err && req.files.length > 0) {
  
            res.status(201).send(`${req.files.length} File(s): ${req.files} uploaded successfully.`);
  
            console.log('uploaded');
  
            resolve();
  
          }
  
        });
  
      });
  
    }
  
  
  
    uploadFile().then(() => {
  
      try {
  
        var process = new ffmpeg('./uploads/' + str);
  
        process.then(function (video) {
  
          console.log('The video is ready to be processed');
  
          video.addCommand('-hide_banner', '');
  
          video.addCommand('-y', '');
  
          video.addCommand('-c:a', 'aac');
  
          video.addCommand('-ar', '48000');
  
          video.addCommand('-c:v', 'h264');
  
          video.addCommand('-profile:v', 'main');
  
          video.addCommand('-crf', '20');

          video.addCommand('-g', '50');

• Discord bot not playing any audio

  7 mars 2023, par Markix

  I'm making a discord music bot with Discord.js v14, @discordjs/voice, and Typescript and I have this play command but it doesn't seem to be working. It successfully joins, throws no exceptions but... no audio.

  


  This is my code :

  


  import { CommandInteraction, SlashCommandBuilder } from "discord.js";
import { joinVoiceChannel, createAudioPlayer, getVoiceConnections, StreamType, AudioPlayerStatus } from "@discordjs/voice";
import { createAudioResource } from "@discordjs/voice";
import ytdl from 'ytdl-core';

module.exports = {
    data: new SlashCommandBuilder()
        .setName('play')
        .setDescription('Play příkaz')
        .addStringOption(option => 
            option
                .setName("link")
                .setDescription("Youtube link!")
                .setRequired(false)
        ),

async execute(interaction: CommandInteraction) {
        const link = interaction.options.get('link')?.value?.toString();
        const player = createAudioPlayer();
        const resource = createAudioResource(ytdl(`${link}`, { filter: "audioonly" }), { inlineVolume: 1.0, inputType: StreamType.WebmOpus });

    player.play(resource);

    const connection = joinVoiceChannel({
        channelId: "775815628619251743",
        guildId: "775761665786511370",
        adapterCreator: interaction.guild?.voiceAdapterCreator,
        selfMute?: false,
        selfDeaf: false
    });

    const subscription = connection.subscribe(player);
    interaction.reply("Now playing: .-.");
}


  


  This is "dependencies" in my package.json

  


    "dependencies": {
    "@discordjs/builders": "^1.2.0",
    "@discordjs/rest": "^1.5.0",
    "@discordjs/voice": "^0.14.0",

  }


  


  (And yes I also have ffmpeg installed globally)

  


  markix@pop-os-lenovo-laptop:~$ apt list --installed | grep -i ffmpeg

  What am I doing wrong ?
