Sending live video frame over network in python opencv

Question

I\'m trying to send live video frame that I catch with my camera to a server and process them. I\'m usig opencv for image processing and python for the language. Here is my

Answer 1

as @Rohan Sawant said i used zmq library without using base64 encoding. here is the new code

Streamer.py

import base64
import cv2
import zmq
import numpy as np
import time

context = zmq.Context()
footage_socket = context.socket(zmq.PUB)
footage_socket.connect('tcp://192.168.1.3:5555')

camera = cv2.VideoCapture(0)  # init the camera

while True:
        try:
                grabbed, frame = camera.read()  # grab the current frame
                frame = cv2.resize(frame, (640, 480))  # resize the frame
                encoded, buffer = cv2.imencode('.jpg', frame)
                footage_socket.send(buffer)


        except KeyboardInterrupt:
                camera.release()
                cv2.destroyAllWindows()
                break

Viewer.py

import cv2
import zmq
import base64
import numpy as np

context = zmq.Context()
footage_socket = context.socket(zmq.SUB)
footage_socket.bind('tcp://*:5555')
footage_socket.setsockopt_string(zmq.SUBSCRIBE, np.unicode(''))

while True:
    try:
        frame = footage_socket.recv()
        npimg = np.frombuffer(frame, dtype=np.uint8)
        #npimg = npimg.reshape(480,640,3)
        source = cv2.imdecode(npimg, 1)
        cv2.imshow("Stream", source)
        cv2.waitKey(1)

    except KeyboardInterrupt:
        cv2.destroyAllWindows()
        break
