OpenCv使用IP摄像头照片

Question

I am trying to work in opencv with a photo that I took with the Android IP camera (http://192.168.0.10:8080/shot.jpg), but it doesnt work, I get a blank window. I tried with another image (http://images2.wikia.nocookie.net/_ cb20110420175105/agallas/es/images/thumb/1/11/Agallas-el-perro-cobarde-125 (1).jpg/640px-Agallas-el-perro-cobarde-125_(1).jpg) and It works perfectly. Why doesn't it work with the photo taken with the ip camera?

  import sys, cv
  import numpy as np
  #photo = "http://images2.wikia.nocookie.net/__cb20110420175105/agallas/es/images/thumb/1/11/Agallas-el-perro-cobarde-125_(1).jpg/640px-Agallas-el-perro-cobarde-125_(1).jpg"
  photo = "http://192.168.0.10:8080/shot.jpg"
  img=cv.CaptureFromFile( photo )
  while True: 
    frame = cv.QueryFrame(img)
    cv.ShowImage('Foto',frame)
    if cv.WaitKey(30)==27:
         break 

Both pictures have the same dimensions

Answer 1

This could be not a very efficient way to solve my problem, but it works.

import urllib
import cv 

urllib.urlretrieve("http://192.168.0.10:8080/shot.jpg", "foto.jpg")
imagen=cv.LoadImage('foto.jpg')
cv.ShowImage('Image',imagen)

Here's some code that I have working to stream from my phone running Android IP Camera, using Andrea Diaz's idea and python with opencv2...

import cv2
import urllib

while True:
    urllib.urlretrieve("http://192.168.0.10:8080/shot.jpg", "foto.jpg")
    src_image = cv2.imread('foto.jpg', 0)
    cv2.imshow('Viewer',src_image)
    # read user keyboard for 5ms, and break on any keypress.    
    if (cv2.waitKey (5) != -1):
        break;
