如何让我的机器人更快地播放音频？ （discord.py 重写）

Question

我的音乐大约需要 30 秒或更长时间才能开始播放音频，我想知道是否有任何方法可以让它像 Groovy 和许多其他机器人一样更快地播放音频。对此的所有帮助表示赞赏。我知道直接从 yt 流式传输是一回事，我的机器人目前下载并提取文件，然后播放它。这是我的代码：

@bot.command(pass_context=True, aliases=['p', 'pla'])
async def play(ctx, url: str):
    global voice
    channel = ctx.message.author.voice.channel
    voice = get(bot.voice_clients, guild=ctx.guild)

    if voice and voice.is_connected():
        await voice.move_to(channel)
    else:
        voice = await channel.connect()

    await voice.disconnect()

    if voice and voice.is_connected():
        await voice.move_to(channel)
    else:
        voice = await channel.connect()
        print(f"The bot has connected to {channel}\n")

    def check_queue():
        Queue_infile = os.path.isdir("./Queue")
        if Queue_infile is True:
            DIR = os.path.abspath(os.path.realpath("Queue"))
            length = len(os.listdir(DIR))
            still_q = length - 1
            try:
                first_file = os.listdir(DIR)[0]
            except:
                print("No more queued song(s)\n")
                queues.clear()
                return
            main_location = os.path.dirname(os.path.realpath(__file__))
            song_path = os.path.abspath(os.path.realpath("Queue") + "\\" + first_file)
            if length != 0:
                print("Song done, playing next queued\n")
                print(f"Songs still in queue: {still_q}")
                song_there = os.path.isfile("song.mp3")
                if song_there:
                    os.remove("song.mp3")
                shutil.move(song_path, main_location)
                for file in os.listdir("./"):
                    if file.endswith(".mp3"):
                        os.rename(file, 'song.mp3')

                voice.play(discord.FFmpegPCMAudio("song.mp3"), after=lambda e: check_queue())
                voice.source = discord.PCMVolumeTransformer(voice.source)
                voice.source.volume = 0.07

            else:
                queues.clear()
                return

        else:
            queues.clear()
            print("No songs were queued before the ending of the last song\n")

我不确定是什么原因导致它变慢，但我认为这可能与您的 pc/host 服务的互联网连接有关，我认为您应该尝试直接从 youtube 流式传输以使其更快

queue = []

YDL_OPTIONS = = {
            "format" : "bestaudio",
            "postprocessors" : [{
                "key" : "FFmpegExtractAudio",
                "preferredcodec" : "mp3",
                "preferredquality" : "192",
            }], "noplaylist" : "True"
        }

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

def play_next():
    queue.pop(0)
    if len(queue) >= 1:
        source = queue[0]['source']
        voice.play(discord.FFmpegPCMAudio(queue[0]['source'], FFMPEG_OPTIONS), after=lambda e: play_next())
        voice.source = discord.PCMVolumeTransformer(voice.source)
        voice.source.volume = 0.07

def lstr(list : Iterable):
        string = f"{list[0]}"
        for i in range(1, len(list)):
            string += f" {list[i]}"
        return string

def search_yt(item):
        with YoutubeDL(YDL_OPTIONS) as ydl:
            try: 
                info = ydl.extract_info("ytsearch:%s" % item, download=False)['entries'][0]
            except Exception: 
                return False

        return {'source': info['formats'][0]['url'], 'title': info['title']}

@bot.command(pass_context=True, aliases=['p', 'pla'])
async def play(ctx, *query):
    query = lstr(query)
    song = search_yt(query)
    queue.append[song]
    global voice
    channel = ctx.message.author.voice.channel
    voice = get(bot.voice_clients, guild=ctx.guild)

    if voice and voice.is_connected():
        await voice.move_to(channel)
    else:
        voice = await channel.connect()

    await voice.disconnect()

    if voice and voice.is_connected():
        await voice.move_to(channel)
    else:
        voice = await channel.connect()
        print(f"The bot has connected to {channel}\n")

    voice.play(discord.FFmpegPCMAudio(queue[0]['source'], FFMPEG_OPTIONS), after=lambda e: play_next())
    voice.source = discord.PCMVolumeTransformer(voice.source)
    voice.source.volume = 0.07

或者你可以找一个主机，这样会更快一点；）
