Live Video Streaming

We can create a live video streaming app using some python libraries like-struct,pandas and cv2.The code for this is given below-

Server Side Code-

import socket,cv2,pickle,struct

client_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
host_ip = ‘192.168.43.216’
port = 9999
client_socket.connect((host_ip, port)) #input tuple
data = b””
payload_size = struct.calcsize(“Q”)
while True:
while len(data) < payload_size:
packet = client_socket.recv(4*480) # 4K
if not packet:
break
data += packet
packed_msg_size = data[:payload_size]
data = data[payload_size:]
msg_size = struct.unpack(“Q”, packed_msg_size)[0]

while len(data) < msg_size:
data += client_socket.recv(4*480)
frame_data = data[: msg_size]
data = data[msg_size:]
frame = pickle.loads(frame_data)
cv2.imshow(“RECEVIVING VIDEO” , frame)
key = cv2.waitKey(1) & 0xFF
if key == ord(‘q’):
break
client_socket.close()

Client Side Code-

import socket, cv2, pickle, struct

server_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
host_name= socket.gethostname()
host_ip = socket.gethostbyname(host_name)
print(‘HOST IP:’, host_ip)
port = 9999
socket_address = (‘192.168.43.216’, port)
server_socket.bind(socket_address)
server_socket.listen(5)
print(“LISTENING AT:”, socket_address)
while True:
client_socket,addr = server_socket.accept()
print(‘GOT CONNECTION FROM’, addr)
if client_socket:
vid = cv2.VideoCapture(0)

while(vid.isOpened()):
img,frame = vid.read()
a = pickle.dumps(frame)
message = struct.pack(“Q”,len(a))+a
client_socket.sendall(message)

cv2.imshow(‘TRANSMISSION VIDEO’, frame)
key = cv2.waitKey(1) & 0xFF
if key == ord(‘q’):
client_socket.close()
