Opencv Camera Interfacing

edit

Hello I am working on a project based on template matching. In my project I am using Rapberry Pi and Logitech C270 HD webcam. When I am trying to take picture from the camera using the sample program (from opencv build directory) I am getting error during compilation:

pi@raspberrypi ~/opencv-2.4.9/finalproject/templet_matching/camera $ ./starter_video 0
HIGHGUI ERROR: V4L/V4L2: VIDIOC_S_CROP
