Discord.py 从 PyAudio 播放语音

Question

我正在尝试将麦克风中的实时音频播放到我的 Discord 机器人中，但我无法将来自 PyAudio 的流转换为 Discord 可以播放的可接受格式。我试过：

async def play_audio_in_voice():
    input_stream = p.open(format = FORMAT,
                channels = CHANNELS,
                rate = RATE,
                input = True,
                frames_per_buffer = CHUNK)
    while True:
        await voice_commands.play_voice(input_stream)

async def play_voice(self, input_stream):
        guild = #got guild here
        if guild.voice_client:
            data = input_stream.read(CHUNK, exception_on_overflow = False)
            voice_client = guild.voice_client
            voice_client.send_audio_packet(data)

并且

async def play_voice(self, input_stream):
        guild = #got guild here
        if guild.voice_client:
            data = input_stream.read(CHUNK, exception_on_overflow = False)
            stream = await discord.FFmpegPCMAudio(data)
            voice_client = guild.voice_client
            voice_client.send_audio_packet(data)

在第一个代码中，我得到：

File "D:\Program Files\lib\site-packages\discord\voice_client.py", line 454, in send_audio_packet
    encoded_data = self.encoder.encode(data, self.encoder.SAMPLES_PER_FRAME)
AttributeError: 'NoneType' object has no attribute 'encode'

我知道每次在这里调用该函数时我都会遇到问题，我现在会解决这个问题:)

discord.FFmpegPCMAudio 自动对您的声音数据进行 Opus 编码。但是 send_audio_packet 不知道您传递的是编码数据还是 non-encoded 数据。

调用send_audio_packet方法时只需添加encode参数：

async def play_voice(self, input_stream):
    ...
    voice_client.send_audio_packet(data, encode=input_stream.is_opus())
