@berak - I have used cv2 also. and used http instead of ftp . But nothing is hapening. The error it is giving is Type Error : an integer is required. Can you provide me with a simple program or solution.

@berak - I have started a new question. Please help me out

I have a laptop running Windows 7 with Python 2.7. I have a webcam attached to the laptop. The laptop has no other webcam. The video is transmitted from this webcam using Yawcam software. The software can transmit videos in streaming , http and ftp protocols. I have arduino micro controller attached to it. I also have a python / twisted socket server running on it to communicate with my desktop. In my desktop I also have windows , python and openCV installed. I want to grab this video in real time and do image processing on it. I used this code to grab the video but with no success

import cv2.cv as cv

cv.NamedWindow("camera", 1)
capture = cv.CaptureFromCAM("ftp://@192.168.1.6:86/");
##capture = cv.CaptureFromCAM(0);
while True:
    img = cv.QueryFrame(capture)
    cv.ShowImage("camera", img)
    if cv.WaitKey(10) == 27:
        break
cv.DestroyWindow("camera")

Ideally i wanted to have openCV in my laptop and transmit videos in realtime using websockets . But I have no clue of doing it. Please help. The best solution would be having openCV at both the ends without any commercial software.

How is "..../mjpg/video.mjpg" the file name coming if the video is being streamed from the web cam by Yawcam or VLC? I want to process with the streaming videos at the client side by using opencv. The webcam is connected to the server and is not IP cam. Please help

@pprahul can you give me a small piece of complete code. I am new to openCV and is planning to give some vision to my robot

I have made an indegenious robot with a small notebook , arduino micro controller and a web camera. The notebook has Ubuntu on it which runs node.js (server) and it transmits the video and data attached to the micro controller to the client computer through WiFi. Presently i am using a free software called Yawcam to transmit video. I have two specific questions 1. Is it possible to do video transmission using OpenCV? or if i capture the video using open CV , how will i transmit it using node.js server(websocket server).

1. I want to process the real time video arriving at my client side with OpenCV and based on the results of video processing , the user will give suitable instructions to the robot. is this possible?

Thanks in advance
