• My music doesn't play correctly and other problems - Discord.py

  24 mars 2021, par Diacono

  So, I'm triying to let my bot play songs directly from the url (without downloading them like the song.mp3 method) but I'm having a hard time. The bot plays only 1 song and when I try to play another song it doesn't play it.
I'm also getting 2 errors : video_link is not defined and self is not defined.
Also when I try to play live music like "lofi hip hop radio - beats to relax/study to" nothing happens.
Can you help me please ???

  


  This is my code

  


  import asyncio
import discord
from discord.ext import commands, tasks
import requests

from random import choice
from discord.utils import get
from discord import FFmpegPCMAudio
import youtube_dl
bot = commands.Bot(command_prefix="!")

}

ytdl = youtube_dl.YoutubeDL(ytdl_format_options)

class YTDLSource(discord.PCMVolumeTransformer):

        super().__init__(source, volume)

        self.data = data

        if 'entries' in data:
            data = data['entries'][0]

        filename = data['url'] if stream else ytdl.prepare_filename(data)
        return cls(discord.FFmpegPCMAudio(filename, **ffmpeg_options), data=data)


@bot.command()

    voice = await ctx.author.voice.channel.connect()
    player = await YTDLSource.from_url(url, loop=client.loop)

• Nodejs youtube-dl ffmpeg audio stream

  19 septembre 2015, par Majster

  I have an issue with streaming video from YouTube. I have a http server which attempts to grab the raw video url, pull out the audio, convert it to mp3 and stream it to clients. The issue is that I’m not getting any audio on my client. Code is below (it’s all work in progress so there’s a lot of hardcoded stuff in there).

  // The obvious stuff
  
  var exec = require('child_process').exec;
  
  var spawn = require('child_process').spawn;
  
  var request = require('request');
  
  var http = require('http');
  
  
  
  //Listen for requests
  
  var server = http.createServer(function(req, response) {
  
     //This command runs youtube-dl and gets the video url
  
     var command = './node_modules/youtube-dl/bin/youtube-dl --simulate --get-url http://www.youtube.com/watch?v=5qF_qbaWt3Q';
  
     var exc = exec(command, function(error, stdout, stderr) {
  
        var downloadUrl = stdout.toString(); //Convert the buffer to string
  
        downloadUrl = downloadUrl.substring(0, downloadUrl.length - 1); //And strip the '\n' sign at the end
  
        console.log("This thing is: '" + downloadUrl + "'");
  
        response.writeHead(200, {
  
           'Content-Type': 'audio/mpeg'
  
        }); //When this is mpeg3 browser will download a blank .mp3 file now it tries to stream it
  
  
  
        //Spawn the ffmpeg child process
  
        var child = spawn('ffmpeg', ['-i', 'pipe:0', '-acodec', 'libmp3lame','-f', 'mp3', '-']);
  
        child.stdout.pipe(response); //Pipe it so it writes to our response
  
  
  
        // fs.createReadStream(filePath).pipe(child.stdin); - this is a testing thing ---> fs is filesystem and filePath is a link to a file - works
  
        request({url: downloadUrl, headers: {'Youtubedl-no-compression': 'True'}}).pipe(child.stdin); //Request the data and pipe it to ffmpeg for processing
  
     });
  
  });

  I can provide any additional info if needed. But the thing works if I try to use a file instead of request call so there is no problem with ffmpeg and other settings. Is it possible that YouTube has a protection against downloading videos this way ? I tried to paste the URL of console.log into my browser and nothing happens - no video. How can I fix this ?

• How to convert a script from youtube-dl

  16 janvier 2020, par danilshik

  There is a bash/batch file script :

  ffmpeg -i `youtube-dl https://www.twitch.tv/zero` -vf fps=fps=60, scale=1920x1080 -c:v libx264 -b:v 500k -preset superfast -c:a copy -f segment -segment_time 60 test.mp4

  The script is not mine, but it allows you to record video with a constant frame rate of parts. Unfortunately in cmd it does not work for me. Already tried everything, I do not know what the error is.

  I am getting No such file or directory.

  Tried 'youtube-dl https://www.twitch.tv/zero', the same error

  I tried "youtube-dl https://www.twitch.tv/zero", error : youtube-dl https://www.twitch.tv/zero: Invalid argument

  What am I doing wrong ? The author assures that he works on linux

  Update

  I tried ffmpeg -i $ (youtube-dl -f best -g https://www.twitch.tv/zero) .... The same error

  Update 2

  Why the video size exceeds 500 Mb ? What am I doing wrong ?

  
  

  Code

  cls && @echo off & setlocal enableextensions enabledelayedexpansion 
  
  set "_tag_00=https://www.twitch.tv/avagg"
  
  set "_tag_01=--ignore-errors --abort-on-error --ignore-config --flat-playlist --geo-bypass "
  
  set "_tag_02=--restrict-filenames --no-part --no-cache-dir --write-thumbnail --prefer-ffmpeg "
  
  set "_tag_03=--ffmpeg-location .\ --postprocessor-args  -i "%%(title)s.%%(ext)s" -vf fps^=fps^=60^,"
  
  set "_tag_04=scale^=1920x1080 -c:v libx264 -b:v 500k -preset superfast -c:a copy -f segment -segment_time "
  
  set "_tag_05=60 %%^(title^)s.mp4"
  
  
  
  youtube-dl "!_tag_00!" -f "bestvideo[ext=mp4]+bestaudio[ext=m4a]/best[ext=mp4]/best" -o "%%^(title^)s.%%^(ext^)s" !_tag_1!!_tag_2!!_tag_3!!_tag_4!!_tag_5!
  
  Pause
