Python PyAudio网络崩溃

您好，我正面临PyAudio的问题，我无法解决。当我在网络上使用它一段时间后，它崩溃了。我得到的错误是

Exception in thread Thread-1: Traceback (most recent call last): File "C:\Python27\lib\threading.py", line 552, in __bootstrap_inner self.run() File "C:\Python27\lib\threading.py", line 505, in run self.__target(*self.__args, **self.__kwargs) File "C:\Users\maboroshi\Desktop\myChat\chat.py", line 71, in server frames_per_buffer = chunk) File "C:\Python27\lib\site-packages\pyaudio.py", line 714, in open stream = Stream(self, *args, **kwargs) File "C:\Python27\lib\site-packages\pyaudio.py", line 396, in __init__ self._stream = pa.open(**arguments) IOError: [Errno Device unavailable] -9985 我的代码在下面，大部分是：-p

这用于解密数据和管理连接

def decrypt_my_message(msg): iv = "1234567812345678" key = your_friends_key if len(key) not in (16, 24, 32): raise ValueError("Key must be 16, 24, or 32 bytes") if (len(msg) % 16) != 0: raise ValueError("Message must be a multiple of 16 bytes") if len(iv) != 16: raise ValueError("IV must be 16 bytes") cipher = AES.new(key, AES.MODE_CBC, iv) plaintext = cipher.decrypt(msg) return plaintext ### Server function ### def server(): HOST = '' PORT = 9001 ### Initialize socket server_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM) server_socket.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1) server_socket.bind((HOST, PORT)) server_socket.listen(5) ### Start recieve loop read_list = [server_socket] while True: readable, writable, errored = select.select(read_list, [], []) for s in readable: if s is server_socket: conn, addr = s.accept() read_list.append(conn) print "Connection from ", addr else: msg = conn.recv(2024) if msg: cmd, msg = ord(msg[0]),msg[1:] if cmd == CMD_MSG: listb1.insert(END, decrypt_my_message(msg.strip()) + "\n") listb1.yview(END) elif cmd == CMD_AUDIO: #d = speex.Decoder() #d.initialize(speex.SPEEX_MODEID_WB) p = pyaudio.PyAudio() stream = p.open(format = FORMAT, channels = CHANNELS, rate = RATE, input = True, output = True, frames_per_buffer = chunk) stream.write(decrypt_my_message(msg), chunk) #Write the data back out to the speakers else: s.close() read_list.remove(s) 这是用来连接和发送加密音频的

任何关于为什么会发生这种情况的想法都是非常有用的

我突然想到的是，你将a与select混合在一起，循环看起来有点奇怪。你在两个方向上都有很多事情要做——试着专注于让数据包的进出像齿轮啮合在一起一样工作，或者确保有人不可能是空的，也不可能是满的

您可能会从以下方面获得一些灵感：

---

我的猜测是，您遇到了问题，因为您正在创建多个PyAudio对象并打开多个流，而没有关闭任何流

---

您应该创建一个PyAudio对象和一个流，然后重新使用这些对象。

这个问题最好直接问PyAudio的开发人员，因为这可能是PyAudio中处理套接字的某种错误。我同意Cerin的观点。看起来是某种套接字错误。也许暂停一下？
