• Node package 'videoshow' ffmpeg error

  14 octobre 2015, par Jon Stevens

  I am using the npm library ’videoshow’ to build a video slideshow with images and audio. I have copied everything directly from the github wiki as far as installing the package and configuring ffmpeg to include the necessary flags. My code for the main ’generation.js’ node file :

  var videoshow = require('videoshow');
  
  
  
  var images = [
  
    '2.jpg',
  
    '4.jpg'
  
  ]
  
  
  
  var videoOptions = {
  
    fps: 25,
  
    loop: 5, // seconds
  
    transition: true,
  
    transitionDuration: 1, // seconds
  
    videoBitrate: 1024,
  
    videoCodec: 'libx264',
  
    size: '640x?',
  
    audioBitrate: '128k',
  
    audioChannels: 2,
  
    format: 'mp4'
  
  }
  
  
  
  videoshow(images, videoOptions)
  
    .audio('song.mp3')
  
    .save('video.mp4')
  
    .on('start', function (command) {
  
      console.log('ffmpeg process started:', command)
  
    })
  
    .on('error', function (err, stdout, stderr) {
  
      console.error('Error:', err)
  
      console.error('ffmpeg stderr:', stderr)
  
    })
  
    .on('end', function (output) {
  
      console.error('Video created in:', output)
  
    })

  Just running the above code with ’node generation.js’ which is the default usage and the exact settings they explain in the wiki is giving the error :

  ffmpeg process started : ffmpeg -i /tmp/videoshow-3fe871bc-e082-4ed8-bf47-f10c854f1718 -i /tmp/videoshow-a1595d76-dcbd-48c3-a8b3-cffac6951ed3 -y -filter_complex concat=n=2:v=1:a=0 video.mp4

  Error : [Error : ffmpeg exited with code 1 : ]

  If anyone has any experience at all with this library, any help is greatly appreciated !

• Music bot doesn't play livestreams anymore

  31 janvier 2019, par Silvinator

  My Discord bot played YT Livestreams all the time, but it stopped working today. The only message I get (in the console) is stream. It plays normal videos, but no streams.
  The question is, why it stopped working ? I did not change any code. Anyone got a idea ?

  client.on("message", async message => {
  
    var args = message.content.substring(prefix.length).split(" ");
  
    if (!message.content.startsWith(prefix)) return;
  
    var searchString = args.slice(1).join(' ');
  
    var url = args[1] ? args[1].replace(/<(.+)>/g, '$1') : '';
  
    var serverQueue = queue.get(message.guild.id);
  
    switch (args[0].toLowerCase()) {
  
      case "play":
  
        var voiceChannel = message.member.voiceChannel;
  
        if (!voiceChannel) return message.channel.send(`Du willst mit mir Karaoke singen? Da ich eh nichts besseres zu tun habe. Du suchst aber den Voice Channel aus!`);
  
        var permissions = voiceChannel.permissionsFor(message.client.user);
  
        if (!permissions.has('CONNECT')) {
  
          return message.channel.send('I cannot connect to your voice channel, make sure I have the proper permissions!');
  
        }
  
        if (!permissions.has('SPEAK')) {
  
          return message.channel.send('I cannot speak in this voice channel, make sure I have the proper permissions!');
  
        }
  
        if (url.match(/^https?:\/\/(www.youtube.com|youtube.com)\/playlist(.*)$/)) {
  
          var playlist = await youtube.getPlaylist(url);
  
          var videos = await playlist.getVideos();
  
          for (const video of Object.values(videos)) {
  
            var video2 = await youtube.getVideoByID(video.id); // eslint-disable-line no-await-in-loop
  
            await handleVideo(video2, message, voiceChannel, true); // eslint-disable-line no-await-in-loop
  
          }
  
          return message.channel.send(`Ich habe wohl keine andere wahl... Ich habe **${playlist.title}** der playlist zugefügt`);
  
        } else {
  
          try {
  
            var video = await youtube.getVideo(url);
  
          } catch (error) {
  
            try {
  
              var videos = await youtube.searchVideos(searchString, 10);
  
              var index = 0;
  
              var videoIndex = 1;
  
              var video = await youtube.getVideoByID(videos[videoIndex - 1].id);
  
            } catch (err) {
  
              console.error(err);
  
              return message.channel.send('Gibt es den Song überhaupt?');
  
            }
  
          }
  
          return handleVideo(video, message, voiceChannel);
  
        }
  
        break;
  
      case "skip":
  
        if (!message.member.voiceChannel) return message.channel.send('Du musst schon in den Voice Channel gehen, baka!');
  
        if (!serverQueue) return message.channel.send('Du musst schon ein song auswählen, baka!');
  
        serverQueue.connection.dispatcher.end('Skip command has been used!');
  
        return undefined;

• Hosting music bot on heroku

  2 mars 2021, par itsmaxplayz

  I have made a discord bot on discord.py rewrite which plays music in a voice channel. The code is as follows :

  


  def search(query):

    with ytdl:
        try:
            requests.get(query)
        except:
            info = ytdl.extract_info(f"ytsearch:{query}", download=False)['entries'][0]
        else:
            info = ytdl.extract_info(query, download=False)
    return info, info['formats'][0]['url']

ydl_opts = {
    'format': 'bestaudio/best',
    'quiet': True,
    'postprocessors': [{
        'key': 'FFmpegExtractAudio',
        'preferredcodec': 'mp3',
        'preferredquality': '192',
    }],

}

ytdl = youtube_dl.YoutubeDL(ydl_opts)

FFMPEG_OPTS = {'before_options': '-reconnect 1 -reconnect_streamed 1 -reconnect_delay_max 5', 'options': '-vn'}

@client.command(aliases=['p'])
async def play(ctx, *, url):
    channel = ctx.message.author.voice.channel
    voice = get(client.voice_clients, guild=ctx.guild)
    if voice and voice.is_connected():
        pass
    else:
        voice = await channel.connect()
        await ctx.send(f'Successfully joined `{channel}`')

    if voice.is_playing():
        await ctx.send('Already playing a song. Try using -q or -queue to queue a song 
    :thumbsup:')
    else:
        await ctx.send(f'Searching for: `{url}` :mag_right:')
        video, source = search(url)
        voice.play(FFmpegPCMAudio(source, **FFMPEG_OPTS))
        voice.is_playing()
        await ctx.send(f'Playing: :notes: `{video["title"]}` - Now!')


  


  It works locally but when I upload the code to heroku (I use github to push the code to heroku), the bot does not come online.
These are the libraries that I imported in the code :

  


  import discord
import json
import random
import youtube_dl
import requests
import os
from discord.ext import commands
from discord.utils import get
from discord import FFmpegPCMAudio
import ctypes
import ctypes.util


  


  I have installed the ffmpeg buildpacks as I saw in another post on this website but the bot doesn't come online.
