Question

我正在尝试将网络摄像头捕获的图像从pi发送到pc，但是在使用套接字编程的同时，我得到了大量的延迟（每个图像大约5-6秒）。我在这里做错什么了吗？有没有办法减少这种延迟，或者有其他更好的技术以最小的延迟将数据发送到pc？

服务器端：

import socket                   

port = 60000                    
s = socket.socket()            
host = ""     
s.bind((host, port))            
s.listen(5)                     

print('Server listening....')

while True:
    conn, addr = s.accept()     
    print 'Got connection from', addr
    data = conn.recv(1024)
    print('Server received', repr(data))

    filename='mytext.txt'
    f = open(filename,'rb')
    l = f.read(1024)
    while (l):
       conn.send(l)
       print('Sent ',repr(l))
       l = f.read(1024)
    f.close()

    print('Done sending')
    conn.send('Thank you for connecting')
    conn.close()

客户：

import socket                   # Import socket module
import time

s = socket.socket()             # Create a socket object
host = "192.1.1.1"              #Ip address that the TCPServer  is there


port = 60000                    # Reserve a port for your service.

s.connect((host, port))
s.send("Hello server!")


with open('received_file.png', 'wb') as f:
    print 'file opened'
    start = time.time()
    while True:
        # print('receiving data...')
        data = s.recv(1024)
        # print('data=%s', (data))
        if not data:
            break
        # write data to a file
        f.write(data)
    print(time.time() - start)

f.close()
print('Successfully get the file')
s.close()
print('connection closed')
