使用python实现http实时视频流

使用opencv读取相机画面，并编码

使用socket实现http multipart/x-mixed-replace 视频流

在浏览器中打开相应的ip端口就能看到

import cv2
import socket

cap = cv2.VideoCapture(0)

server_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
server_socket.bind(('',8080))
server_socket.listen()

print('listen')
csock, caddr = server_socket.accept()
print('GOT CONNECTION FROM:', caddr)
res = b'HTTP/1.1 200 OK\r\nContent-Type: multipart/x-mixed-replace;boundary=frame\r\n\r\n'
csock.send(res)

while 1:
    ret, frame = cap.read()
    if not ret:
        continue
    ret, buffer = cv2.imencode('.jpg', frame)
    frame = buffer.tobytes()
    res = b'--frame\r\nContent-Type: image/jpeg\r\n\r\n'+frame+b'\r\n'
    csock.send(res)
