【中文标题】不和谐.py |从 url 播放音频【英文标题】：discord.py | play audio from url 【发布时间】：2021-05-12 20:40:09 【问题描述】：我想让我的机器人从 url 播放音频，但我不想下载文件...
这是我的代码：
@commands.command(name='test')
async def test(self, ctx):
search = "morpheus tutorials discord bot python"
if ctx.message.author.voice == None:
await ctx.send(embed=Embeds.txt("No Voice Channel", "You need to be in a voice channel to use this command!", ctx.author))
return
channel = ctx.message.author.voice.channel
voice = discord.utils.get(ctx.guild.voice_channels, name=channel.name)
voice_client = discord.utils.get(self.client.voice_clients, guild=ctx.guild)
if voice_client == None:
await voice.connect()
else:
await voice_client.move_to(channel)
search = search.replace(" ", "+")
html = urllib.request.urlopen("https://www.youtube.com/results?search_query=" + search)
video_ids = re.findall(r"watch\?v=(\S11)", html.read().decode())
#################################
await ctx.send("https://www.youtube.com/watch?v=" + video_ids[0])
# AND HERE SHOULD IT PLAY
#################################
我尝试了 create_ytdl_player 方法，但发现它不再支持我该怎么办？
【问题讨论】：
你可以看看discord.py github repo中的一个例子，link 我正在尝试使用这条线： ctx.voice_client.play(url, after=lambda e: print('Player error: %s' % e) if e else None) 但后来我得到了错误，需要音频源而不是 str 【参考方案1】：如果需要，请将 bot 替换为 client。然后，试试这个：
import asyncio
import discord
import youtube_dl
from discord.ext import commands
# Suppress noise about console usage from errors
youtube_dl.utils.bug_reports_message = lambda: ''
ytdl_format_options =
'format': 'bestaudio/best',
'outtmpl': '%(extractor)s-%(id)s-%(title)s.%(ext)s',
'restrictfilenames': True,
'noplaylist': True,
'nocheckcertificate': True,
'ignoreerrors': False,
'logtostderr': False,
'quiet': True,
'no_warnings': True,
'default_search': 'auto',
'source_address': '0.0.0.0' # bind to ipv4 since ipv6 addresses cause issues sometimes
ffmpeg_options =
'options': '-vn'
ytdl = youtube_dl.YoutubeDL(ytdl_format_options)
class YTDLSource(discord.PCMVolumeTransformer):
def __init__(self, source, *, data, volume=0.5):
super().__init__(source, volume)
self.data = data
self.title = data.get('title')
self.url = data.get('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(description="joins a voice channel")
async def join(self, ctx):
if ctx.author.voice is None or ctx.author.voice.channel is None:
return await ctx.send('You need to be in a voice channel to use this command!')
voice_channel = ctx.author.voice.channel
if ctx.voice_client is None:
vc = await voice_channel.connect()
else:
await ctx.voice_client.move_to(voice_channel)
vc = ctx.voice_client
@commands.command(description="streams music")
async def play(self, ctx, *, url):
async with ctx.typing():
player = await YTDLSource.from_url(url, loop=self.bot.loop, stream=True)
ctx.voice_client.play(player, after=lambda e: print('Player error: %s' % e) if e else None)
await ctx.send('Now playing: '.format(player.title))
@commands.command(description="stops and disconnects the bot from voice")
async def leave(self, ctx):
await ctx.voice_client.disconnect()
@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(bot):
bot.add_cog(Music(bot))
这不仅会从 URL 播放，还会从视频本身的名称播放。
【讨论】：
【参考方案2】：使用pafy。
首先导入一些东西并设置 FFmpeg 选项...
import pafy
from discord import FFmpegPCMAudio, PCMVolumeTransformer
FFMPEG_OPTIONS = 'before_options': '-reconnect 1 -reconnect_streamed 1 -reconnect_delay_max 5','options': '-vn'
那就玩吧
@commands.command(name='test')
async def test(self, ctx):
search = "morpheus tutorials discord bot python"
if ctx.message.author.voice == None:
await ctx.send(embed=Embeds.txt("No Voice Channel", "You need to be in a voice channel to use this command!", ctx.author))
return
channel = ctx.message.author.voice.channel
voice = discord.utils.get(ctx.guild.voice_channels, name=channel.name)
voice_client = discord.utils.get(self.client.voice_clients, guild=ctx.guild)
if voice_client == None:
voice_client = await voice.connect()
else:
await voice_client.move_to(channel)
search = search.replace(" ", "+")
html = urllib.request.urlopen("https://www.youtube.com/results?search_query=" + search)
video_ids = re.findall(r"watch\?v=(\S11)", html.read().decode())
await ctx.send("https://www.youtube.com/watch?v=" + video_ids[0])
song = pafy.new(video_ids[0]) # creates a new pafy object
audio = song.getbestaudio() # gets an audio source
source = FFmpegPCMAudio(audio.url, **FFMPEG_OPTIONS) # converts the youtube audio source into a source discord can use
voice_client.play(source) # play the source
【讨论】：
请为您的答案添加更多解释 抱歉，出现错误。你需要解压 FFmpeg 选项，我刚刚更新了我的答案【参考方案3】：如果source 参数是str，则它在内部由FFmpegPCMAudio 作为ffmpeg 二进制文件的输入直接输入。
ffmpeg 支持 url 作为开箱即用的输入。所以你可以只传递 url 而不是文件路径。
source = FFmpegPCMAudio("https://example.com/demo.mp3", executable="ffmpeg")
ctx.voice_client.play(source, after=None)
