[英]using pygame to stream over sockets in python error
i am working on with a webcam script i got of the internet in python and i am using pygame module the code is 我正在研究一个网络摄像头脚本,我在python中使用了互联网,我正在使用pygame模块代码
import socket
import pygame
import sys
port=5014
#create pygame screen
screen = pygame.display.set_mode((800,600),0)
while True:
s=socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.bind(("",port)) # server is available on the whole network by setting host to ""
s.listen(1)
connection, addr = s.accept()
received = []
# loop .recv, it returns empty string when done, then transmitted data is completely received
while True:
recvd_data = connection.recv(1440021)
if not recvd_data:
break
else:
received.append(recvd_data)
dataset = ''.join(received)
image = pygame.image.fromstring(dataset,(800,600),"RGB") # convert received image from string
#image = pygame.transform.scale(image,(800,600)) # scale image to 800*600
screen.blit(image,(0,0)) # "show image" on the screen
pygame.display.update()
# check for quit events
for event in pygame.event.get():
if event.type == pygame.QUIT:
pygame.quit()
sys.exit()
and the client code is 而客户端代码是
import socket
import pygame
import pygame.camera
import sys
import time
host = "localhost"
port = 5014
pygame.init()
pygame.camera.init()
cam_list = pygame.camera.list_cameras() # list available cameras
webcam = pygame.camera.Camera(cam_list[0],(800,600)) # use first camera in list and set resolution
webcam.start() # start camera
while True:
image = webcam.get_image() # capture image
data = pygame.image.tostring(image,"RGB") # convert captured image to string, use RGB color scheme
#print sys.getsizeof(data) # in case somebody wants to know the size of the captured image
# prepare for connection to server
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM) # TCP is used
s.connect((host, port))
s.sendall(data)
s.close()
time.sleep(0.1)
the error i get on the server is 我在服务器上得到的错误是
Traceback (most recent call last):
File "/root/Desktop/serv.py", line 29, in <module>
image = pygame.image.fromstring(dataset,(800,600),"RGB") # convert received image from string
ValueError: String length does not equal format and resolution size
and the error i get on the client is 我在客户端上得到的错误是
Traceback (most recent call last):
File "/root/Desktop/cli.py", line 28, in <module>
s.sendall(data)
File "/usr/lib/python2.7/socket.py", line 224, in meth
return getattr(self._sock,name)(*args)
socket.error: [Errno 104] Connection reset by peer
does anyone know what could be wrong 有谁知道什么可能是错的
I was using the same code and getting a similar error, the solution was to lower the resolution of the webcam because mine could not handle the 800x600. 我使用相同的代码并得到类似的错误,解决方案是降低网络摄像头的分辨率,因为我无法处理800x600。
I also changed the "server" and "client" so the weebcam server acts like the "socket server" 我还更改了“服务器”和“客户端”,因此weebcam服务器就像“套接字服务器”
try the following code, make sure that your video is correct, on my example "/dev/video0" yours could be different. 尝试下面的代码,确保您的视频是正确的,在我的示例“/ dev / video0”上,您的视频可能会有所不同。 Start the webcam server first.
首先启动网络摄像头服务器。
Webcam server: 摄像头服务器:
import socket
import pygame
import pygame.camera
import sys
import time
port = 5000
pygame.init()
serversocket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
serversocket.bind(("",port))
serversocket.listen(1)
pygame.camera.init()
webcam = pygame.camera.Camera("/dev/video0",(320,240))
webcam.start()
while True:
connection, address = serversocket.accept()
image = webcam.get_image() # capture image
data = pygame.image.tostring(image,"RGB") # convert captured image to string, use RGB color scheme
connection.sendall(data)
time.sleep(0.1)
connection.close()
Client server: 客户端服务器:
import socket
import pygame
import sys
host = "10.0.0.13"
port=5000
screen = pygame.display.set_mode((320,240),0)
while True:
clientsocket=socket.socket(socket.AF_INET, socket.SOCK_STREAM)
clientsocket.connect((host, port))
received = []
# loop .recv, it returns empty string when done, then transmitted data is completely received
while True:
#print("esperando receber dado")
recvd_data = clientsocket.recv(230400)
if not recvd_data:
break
else:
received.append(recvd_data)
dataset = ''.join(received)
image = pygame.image.fromstring(dataset,(320,240),"RGB") # convert received image from string
screen.blit(image,(0,0)) # "show image" on the screen
pygame.display.update()
# check for quit events
for event in pygame.event.get():
if event.type == pygame.QUIT:
pygame.quit()
sys.exit()
