我正在编写服务器 - 客户端视频流,服务器获取客户端摄像头捕获的视频。
我的程序正在运行,但我的问题是视频非常慢,有9 +秒的延迟,我想知道如何加快速度以获得更好的性能?
这是我的服务器:
import socket
import cv2
import pickle
import struct
HOST = '0.0.0.0'
PORT = 8765
s=socket.socket(socket.AF_INET, socket.SOCK_STREAM)
print 'Socket created'
s.bind((HOST, PORT))
print 'Socket bind complete'
s.listen(1)
print 'Socket now listening'
conn, addr = s.accept()
data = ""
payload_size = struct.calcsize("L")
while True:
while len(data) < payload_size:
data += conn.recv(131072)
packed_msg_size = data[:payload_size]
data = data[payload_size:]
msg_size = struct.unpack("L", packed_msg_size)[0]
while len(data) < msg_size:
data += conn.recv(131072)
frame_data = data[:msg_size]
data = data[msg_size:]
frame=pickle.loads(frame_data)
#print frame.size
cv2.imshow('frame', frame)
cv2.waitKey(1)
这是我的客户:
import cv2
import socket
import pickle
import struct
cap = cv2.VideoCapture(0)
clientsocket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
clientsocket.connect(('localhost', 8765))
while True:
ret,frame = cap.read()
data = pickle.dumps(frame)
clientsocket.sendall(struct.pack("L", len(data)) + data)
感谢您的帮助!
