PyAudio通过网络崩溃
你好，我正面临PyAudio的问题，我无法解决。 当我通过网络使用它时（过了一段时间）它崩溃了。 我得到的错误是
Exception in thread Thread-1:
Traceback (most recent call last):

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):

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)
这是用于连接和发送加密音频

root.destroy()
#x = event.char
if event.keysym == 'Control_L':

client(chr(CMD_AUDIO), sendAudio())
#print("Data Sent!")
任何想法，为什么发生这将是最有帮助的
跳到我身上的事情是，你正在混合一个可以阻止select的线程，而且这个循环看起来有点奇怪。 你有很多东西在两个方向上发生 - 试着把注意力集中在让数据包流入和流出像齿轮啮合在一起，或者确保没有办法让某人在空闲或充满时，预计不会。
你可能会从以下方面找到一些启发
我的猜测是，你遇到了问题，因为你正在创建多个PyAudio对象并打开多个流而没有关闭任何它们。
您应该创建一个PyAudio对象和一个流，并重新使用这些对象。
