• How to delete mp3 file after the bot played it

  8 mars 2021, par EckigerLuca

  I am trying to create a music bot and now I want the bot to delete the current playing song after it finished playing. There's my code :

  


  import asyncio

import os
import discord
from discord.embeds import Embed
from discord.file import File
from discord.player import AudioPlayer
from youtube_dl.utils import smuggle_url, update_url_query
from youtube_search import YoutubeSearch
import discord
from discord.ext.commands import bot
import youtube_dl
from discord.ext import commands
from youtube_dl import YoutubeDL

youtube_dl.utils.bug_reports_message = lambda: ''

ytdl_format_options = {
    'format': 'bestaudio/best',
    'outtmpl': '/music_files/%(id)s.mp3',
    'restrictfilenames': True,
    'noplaylist': True,
    'nocheckcertificate': True,
    'ignoreerrors': False,
    'logtostderr': False,
    'quiet': True,
    'no_warnings': True,
    'default_search': 'auto',
    'source_address': '0.0.0.0' 
}

ffmpeg_options = {
    'options': '-vn'
}

ytdl = youtube_dl.YoutubeDL(ytdl_format_options)


class YTDLSource(discord.PCMVolumeTransformer):
    def __init__(self, source: discord.FFmpegPCMAudio, *, data: dict, volume=0.5):
        super().__init__(source, volume)

        self.data = data

        self.title = data.get('title')
        self.thumbnail = data.get('thumbnail')
        self.url = data.get('webpage_url')
        self.uploader = data.get('uploader')
        self.uploader_url = data.get('uploader_url')

    @classmethod
    async def from_url(cls, url, *, loop=None, stream=False):
        loop = loop or asyncio.get_event_loop()
        data = await loop.run_in_executor(None, lambda: ytdl.extract_info(url, download=not stream))

        if 'entries' in data:
            # take first item from a playlist
            data = data['entries'][0]

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

class Music(commands.Cog):
    def __init__(self, bot):
        self.bot = bot


    @commands.command()
    async def play(self, ctx, *, url):
        global player
        """Plays from a url (almost anything youtube_dl supports)"""
        async with ctx.typing():
            player = await YTDLSource.from_url(url, loop=self.bot.loop)
            ctx.voice_client.play(player, after=lambda e: print('Player error: %s' % e) if e else None)

            await ctx.send("Started playing!")
    @play.before_invoke
    async def ensure_voice(self, ctx):
        if ctx.voice_client is None:
            if ctx.author.voice:
                await ctx.author.voice.channel.connect()
            else:
                await ctx.send("You are not connected to a voice channel.")
                raise commands.CommandError("Author not connected to a voice channel.")
        elif ctx.voice_client.is_playing():
            ctx.voice_client.stop()

def setup(client):
    client.add_cog(Music(client))


  


  It's saving the files to a folder called "music_files" with the format videoid.mp3
I noticed that it's logging something in the cmd when logging.basicConfig(level=logging.INFO) is added to the main.py file under the imports, is there maybe a way to use it ?

  


  Note : The code is a modified version of basic_voice.py by Rapptz.

  


  Edit : I found a way :

  


              folder = './music_files'
            for song in os.listdir(folder):
                file_path = os.path.join(folder, song)
                try:
                    if os.path.isfile(file_path) or os.path.islink(file_path):
                        os.unlink(file_path)
                    elif os.path.isdir(file_path):
                        shutil.rmtree(file_path)
                except Exception as e:
                    print('Failed to delete %s. Reason %s' % (file_path, e))


  


• Example of streaming YouTube audio using FFMPEG

  15 avril 2020, par Dupe

  I would like to use FFMPEG to stream YouTube audio to another source

  



  using (var ffmpeg = CreateProcess(track.GetUrl()))
using (var stream = client.CreatePCMStream())
{
    try { await ffmpeg.StandardOutput.BaseStream.CopyToAsync(stream); }
    finally { await stream.FlushAsync(); }
}


  



  Where CreateProcess() looks like this :

  



  private Process CreateProcess(string url)
{
    return Process.Start(new ProcessStartInfo
    {
        FileName = "ffmpeg.exe",
        Arguments = $"-hide_banner -loglevel panic -i \"{url}\" -ac 2 -f s16le -ar 48000 pipe:1",
        UseShellExecute = false,
        RedirectStandardOutput = true
    });
}


  



  

  • url represents the YouTube video URL.

  


  • client represents a Discord audio client, to which I want to copy the stream to.

  


  • I am using Discord.Net (latest stable).

  


  



  The arguments do not seem to be correct as there is no playback and no such exception is returned.

  


• ffmpeg doesn't see yt_dlp stream

  24 décembre 2022, par matiz22

  I making discord bot and i am trying to move from youtube_dl to yt_dlp to get +18 videos from youtube, I am getting error Output file #0 does not contain any stream.

  


  self.YTDL_OPTIONS = {'format': 'bestaudio', 'nonplaylist': 'True', 'youtube_include_dash_manifest': False}

self.FFMPEG_OPTIONS = {
    'before_options': '-reconnect 1 -reconnect_streamed 1 -reconnect_delay_max 5',
    'options': '-vn'
}


  


  with YoutubeDL(self.YTDL_OPTIONS) as ydl:
    try:
        info = ydl.extract_info(url, download=False)
    except:
        return False
return {
    'link': 'https://www.youtube.com/watch?v=' + url,
    'thumbnail': 'https://i.ytimg.com/vi/' + url + '/hqdefault.jpg?sqp=-oaymwEcCOADEI4CSFXyq4qpAw4IARUAAIhCGAFwAcABBg==&rs=AOn4CLD5uL4xKN-IUfez6KIW_j5y70mlig',
    'source': info['formats'][0]['url'],
    'title': info['title']
}


  


  self.vc[id].play(discord.FFmpegPCMAudio(
    song['source'], **self.FFMPEG_OPTIONS), after=lambda e: self.play_next(interaction))


  


  This config works with youtube_dl, but not with yt_dlp. Any ideas what i should change ?
