I have been trying to use my logitech camera using: 

CvCapture* capture = cvCaptureFromCAM(1);

My laptop already have a built-in camera and it's working fine I'm using openCV 2.3 in Visual Studio 2010 All sources i'm finding are using libraries for VS 2008 I don't think that they work for 2010 (I've tried one before) Is there anyway to do it?

  • It looks like C. C++ would be something like `cv::VideoCapture cap(1);` – juanchopanza Apr 23 '12 at 13:04
  • Ummm, I don't know if this works. But can you provide me with a simple example to test it? I'm relatively a beginner at openCV – user1347945 Apr 23 '12 at 13:26

  • I doubt it will help, but I put something [here](http://pastebin.com/i0Kb2xNv). But I use linux and I can figure out what is going on at the OS level, although for my logitech camera I didn't have to do anything special. – juanchopanza Apr 23 '12 at 13:34
  • @karlphillip it is a possible duplication, I've seen that one before posting (stackoverflow has a very nice search engine when you type the title) however, that question had several different circumstances as well as it didn't help me much :) – user1347945 Apr 23 '12 at 19:38

What is the reference of your logitech camera ? Here is a list of compatible camera tested with opencv.

  • could it be the camera itself? I thought that the method i'm using cannot be used for cameras connected via USB – user1347945 Apr 23 '12 at 13:33

    VideoCapture::VideoCapture(int device) -- device = id of the opened video capturing device (i.e. a camera index). If there is a single camera connected, just pass 0. – Eric Apr 23 '12 at 13:35
