python - 不和谐机器人在哪里可以找到 ffmpeg buildpack heroku

Question

我正在制作一个机器人，它将一个 mp3 文件输出到与 discord.py 的语音聊天中，它通过以下方式在本地工作:vc.play(discord.FFmpegPCMAudio(executable="ffmpeg/bin/ffmpeg.exe", source=noise.mp3))但是我现在将它托管在 Heroku 上，我已经安装了 buildpack，但是我的代码如何访问它来替换上面的代码

Answer 1

您没有包含您的代码，所以我不知道您是否希望它在您在不和谐中编写命令时或当机器人准备好 时播放它，所以我决定在它准备好时让机器人播放(如果你想要它要加入命令，您可以修改我的代码)。另外，我认为如果您为此使用 youtube_dl 会更容易。

import discord
from discord.ext import commands
import youtube_dl

Token = "XXXXXX" #your token         
client = commands.Bot(command_prefix = ":") 


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

def endSong(guild, path):
    os.remove(path)

url = "https://www.youtube.com/watch?v=dQw4w9WgXcQ" #link to your song on YouTube
with youtube_dl.YoutubeDL(ydl_opts) as ydl:
    file = ydl.extract_info(url, download=True)
    guild = "1234567890" #id of your server which you can get by right clicking on server name and clicking "Copy ID" (developer mode must be on)
    path = str(file['title']) + "-" + str(file['id'] + ".mp3")

channel = client.get_channel(1234567890) #id of your channel (you get it like server id, but by right clicking on channel)                         
voice_client = await channel.connect()                                           

voice_client.play(discord.FFmpegPCMAudio(path), after=lambda x: endSong(guild, path))
voice_client.source = discord.PCMVolumeTransformer(voice_client.source, 1)
    
while voice_client.is_playing(): #waits until song ends
    await asyncio.sleep(1)
else:
    await voice_client.disconnect() #and disconnects
    print("Disconnected")

还要记住在 Heroku 上包含 4 个构建包，以确保一切正常( Your APP > Settings > Buildpacks):

heroku/python

https://github.com/heroku/heroku-buildpack-apt.git

https://github.com/jonathanong/heroku-buildpack-ffmpeg-latest.git

https://github.com/xrisk/heroku-opus.git

并检查您的 requirements.txt 中是否包含所有这些:
