The key point here is the use of getPixels method that will write what the camera sees into the buffer. tVideoSettingCamera(mDeviceNb, CameraControl_Focus, mDefaultFocus, CameraControl_Flags_Manual) Create the buffer where the video will be captured MHeight = mVideoInput.getHeight(mDeviceNb) MWidth = mVideoInput.getWidth(mDeviceNb) make sure to check the size once the device is setup

As requested width and height can not always be accomodated tupDevice(mDeviceNb, width, height, VI_COMPOSITE) Setup device with video size and connection type The constructor implementation uses videoInput :Д¬ameraWindows::CameraWindows( const int deviceNb, const int width, const int height ) : The constructor initializes all camera properties, there is a method to fetch new frames from the camera, a method to get the previously captured frameВ and the destructor which disconnects the device and frees up allВ resources.Д¬ameraWindows( const int deviceNb = 0, const int width = 1024, const int height = 720) The CameraWindows class manages all the camera functions and settings. CMakeLists.txt : the configuration file for our project.CameraWindows.cpp : the camera class that uses VideoInput as its backend.VideoInput/videoInputLib.a : the precompiled VideoInput lib to be linked to our project.VideoInput/include : contains the header that will be used in our project.VideoInput/DShow : includes all libs used by VideoInput library itself.The root folder is organized in two subfolders :

Feel free to modify it and to use it as inspiration for your own projects. The project is functional but incomplete.

In this post I will show you how to easily interface the videoInput library with OpenCV. However, I find it easier to copy all necessary files into a 3rd party folder and configure the project using those files and cmake. This library is already usedВ internallyВ in opencv and can be found somewhere in theВ source code. You can find the sources here, and the old site here. Theo developedВ a very useful video capture library for windows called videoInput.

The disadvantage : theyвЂ™re not usually multi platform so youвЂ™ll find yourself writing classes for every platform where youвЂ™re camera device operates. To sort out this problem, one could use specialized libraries.

You can capture video from your camera without a hassle but youвЂ™re very limited to what you can do.ДЇor instance, letвЂ™s say you have a webcam that can run at HD resolution ( 1280 x 720 px ), you can use the opencvвЂ™s class cv::VideoCapture to get the frames but youвЂ™re going to have a hard time on getting the full resolution out of your device. As you might have already noticed, the internalвЂ™s opencv camera interface is far from complete.
