There are a lot of reason why you didn't have success. E.g. you didn't provide username and password before getting stream. If this camera provides MJPEG (you can find this info in specification of the camera), you should discuss with Sony or do reverse engineering to understand what specific protocol should be used for this camera. Aleksey Hi David,

As an input parameter for these function i use: http://username:psw@ip_addr/image What i am doing wrong ? thanks, Hi, I have a wireless sony camera snc-rz30n and I am trying to grab frames using the function cvCreateFileCapture_FFMPEG and cvCaptureFromFile and i did not success, the value these functions returned is NULL.

I'm using openCV 2.1. Great blog man! HI,
I successfully retrieve the cam mjpg stream from axis 214 PTZ in this way

CvCapture* capture=cvCaptureFromFile(“http://192.168.1.85/axis-cgi/mjpg/video.cgi?resolution=320×240″);

but this does not work for Axis P1343 and Axis Q1910, why?
I’m using openCV 2.1.
Great blog man!

We did not work with libraries you mentioned, but from brief look at them, there are no reasons why you can not use them. You also can look at OpenCV as it provides some capabilities for contour extraction and object tracking. Regards, Sergey Hello Foong,

The program should detect the object in real time and display the coordinates in real time while moving the object. Thank you.. Hi Aleksey I have a project can you help me please,

My project:
 Let a webcam be connected to your computer
 You should write a program satisfying the following scenario: Put an object of your choice in front of the camera, then the program will detect the screen coordinates and display them at the bottom left of the screen. The program should detect the object in real time and display the coordinates in real time while moving the object.

Thank you..

You can look at the auto-generated code and find out difference between it and videoinput library. Hi Jamma,
