• How to get best audio quality on music bot using discord.py ?

  9 mai 2021, par user28606

  I've built a discord music bot in discord.py but for some reason, it doesn't play music in as high quality as Fredboat or Rythm(so I don't think voice chat's bitrate is the problem). I've tried a couple of things online.

  


  The only thing that improved quality a little bit was downloading the song before playing it. But the quality was still far from anything like Fredboat's. It's also very impractical since downloading a 1h song takes a while and is space consuming.

  


  I'm interested in how to fix this and the explanation for why this is happening.

  


  This is the code we're currently using for the music bot :

  


  from discord import FFmpegPCMAudio
import discord
from apscheduler.schedulers.asyncio import AsyncIOScheduler
from apscheduler.triggers.cron import CronTrigger
from discord.ext import commands, tasks
from youtubesearchpython import VideosSearch

class cmd_music(commands.Cog, name="music_commands"):

    def __init__(self, bot):
        self.bot = bot
        self.music_queue = []
        self.scheduler = AsyncIOScheduler()
        self.scheduler.add_job(self.check_queue, CronTrigger(second="0,5,10,15,20,25,30,35,40,45,50,55"))
        self.scheduler.start()
    
    async def play_raw(self, voice_client):
        if not self.music_queue:
            return

        YDL_OPTIONS = {'format': 'bestaudio', 'noplaylist':'True'}
        FFMPEG_OPTIONS = {'before_options': '-reconnect 1 -reconnect_streamed 1 -reconnect_delay_max 5', 'options': '-vn'}
        if not voice_client.is_playing():
            with YoutubeDL(YDL_OPTIONS) as ydl:
                info = ydl.extract_info(self.music_queue.pop(0), download=False)
            URL = info['formats'][0]['url']
            voice_client.play(FFmpegPCMAudio(URL, **FFMPEG_OPTIONS))
            voice_client.is_playing()

    async def check_queue(self):
        if not self.bot.voice_clients: return
        
        client = self.bot.voice_clients[0]
        if not client.is_playing():
            if self.music_queue:
                await self.play_raw(client)
           
        
    @commands.command(brief="join")
    async def join(self, ctx):
        await ctx.author.voice.channel.connect()

    @commands.command(brief="leave")
    async def leave(self, ctx):
        await ctx.voice_client.disconnect()
        self.music_queue = []

    @commands.command(brief="play")
    async def play(self, ctx, *name):
        url = VideosSearch(" ".join(name[:]), 1).result().get("result")[0].get("link")
        self.music_queue.append(url)
        await ctx.send("Now playing: " + url)

    @commands.command(brief="skip")
    async def skip(self, ctx):
        await ctx.send("Skipped current song")
        ctx.voice_client.stop()
        if self.music_queue:
            await self.play_raw(ctx.voice_client)```

  I want to start a song file at a specific time with ffmpeg in python and I don’t know if this is possible. I make a discord bot and I want to make a command about this. Thank you for any help !

  avcodec/vaapi : increase av1 decode pool size
  For film grain clip, vaapi_av1 decoder will cache additional 8
  
  surfaces that will be used to store frames which apply film grain.
  
  So increase the pool size by plus 8 to avoid leak of surface.
