如何使用python通过套接字编程发送多个连续值(即视频帧、信号)

import socket
import struct
import cv2

client_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
server_address = ('目标主机IP', 目标主机端口)
client_socket.connect(server_address)

video_capture = cv2.VideoCapture('视频文件路径')  # 或者使用摄像头：cv2.VideoCapture(0)

while True:
    # 读取视频帧
    ret, frame = video_capture.read()
    
    # 将帧数据转换为字符串
    frame_data = frame.tostring()
    
    # 获取帧数据的长度
    frame_length = len(frame_data)
    
    # 将帧数据长度打包为4字节的二进制数据
    length_data = struct.pack('!I', frame_length)
    
    # 发送帧数据长度
    client_socket.sendall(length_data)
    
    # 发送帧数据
    client_socket.sendall(frame_data)

client_socket.close()
video_capture.release()
