• When I try to play my Music Discord Bot it doesn't play music

  1er juin 2020, par EthanDevelops

  When I try to play my Music Discord Bot it doesn't play music. It uses ytdl-core and ffmpeg
My code is :

  



  const Discord = require('discord.js');
const bot = new Discord.Client

const ytdl = require("ytdl-core")


const token = 'API TOKEN'

const PREFIX = '?';

var version = '1.2';

var servers = {};

bot.on('ready', () =>{
    console.log('This bot is online!' + version);
})

bot.on('message', message => {

    let args = message.content.substring(PREFIX.length).split(" ");

    switch(args[0]){
        case 'play':

            function play(connection, message){
                var server = servers[message.guild.id];

                server.dispatcher = connection.play(ytdl(server.queue[0], {filter: "audioonly"}))

                server.queue.shift();

                server.dispatcher.on("end", function(){
                    if(server.queue[0]){
                        play(connection, message);
                    }else {
                        connection.disconnect();
                    }
                });



            }



            if(!args[1]){
                message.channel.send("You need to provide a link!")
                return;
            }

            if(!message.member.voice.channel){
               message.channel.send("You must be in a Voice Channel to play the bot!")
               return;
            }

            if(!servers[message.guild.id]) servers[message.guild.id] = {
                queue: []
            }

            var server = servers[message.guild.id];

            server.queue.push(args[1]);

            if(!message.guild.voice) message.member.voice.channel.join().then(function(connection){
                play(connection, message);
            })

        break;
    }



    });


    bot.login(token);

• How do I fade out the edge of a video with ffmpeg ?

  11 décembre 2020, par Jared

  I have a transparent .mov and I want to "fade out" only one edge of the video into transparency using ffmpeg.

  


  My video is transparent 1000x1000 (black is transparent) :

  



  I am trying this command :

  


   ffmpeg -i movie.mov -b:v 700K -filter_complex "[0]split[v0][v1];[v0]format=yuva420p,geq=r=0:g=0:b=0:a=255*(Y/H),scale=w=1*iw:h=200[fg];[v1][fg]overlay=0:800:shortest=1" converted.mov


  


  This half works as the image has the gradient fade out but loses all transparency :

  



  What am I doing wrong ?

  


  Full output log of command :
