• 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.

  


  Contents of my requirement file :

  


  discord.py,
discord.py[voice],
ffmpeg,
PyNaCl,
youtube_dl,
requests,
discord.py[FFmpegPCMAudio],
colorlog.

  


• How to live stream from Windows 10 app to Youtube ?

  12 août 2015, par Boland

  I’m playing around with the YouTube Live Stream API. That’s working fine so far, but the next step is to stream the web cam data to YouTube via RTMP.

  In the (excellent) documentation at Google Dev, it outlines the Life of a Broadcast. However, all steps are documented in detail, except the step I’m interested in :

  Step 3.2 : Start your video

  Start transmitting video on your video stream.

  I was able to use Open Broadcasting Software to stream to a manually created YouTube Live Event, but I have no idea how to do it from my Windows 10 App. I’ve looked at the MediaElement class, and was able to capture the web cam preview in my app. But I can only find methods to save as a file.

  Also found information about FFMPEG, which should probably be able to do the job, but I cannot find a library / DLL to use FFMPEG in my App.

  I just need some guidance where to look next, because now I’m just clueless what to do.

  /edit : I came across MPlatform SDK, which sounds exactly what I want, but it costs $5000.... Not for a hobby :(

• Livestreaming screencast to Youtube through ffmpeg doesn't show video even though data is received [duplicate]

  I am trying to livestream my Desktop in Ubuntu to Youtube and used this cmd. Youtube livestream showed green bar with "Receiving your data" and Youtube log also showed "Stream healthy", however no video showed up in Youtube player, and after a short while Youtube log said "Stream complete". What’s missing in my cmd ?

  ffmpeg -f x11grab -r 10 -s 1024x720 -i :0.0 -vcodec libx264 -pix_fmt yuv420p -preset ultrafast -g 20 -b:v 2500k -threads 0 -bufsize 512k -f flv rtmp ://a.rtmp.youtube.com/live2/myKey

  BTW, only screencasting doesn’t work for me, streaming a video file works for me.
