Here you can find the reference for the VideoCapture class which will help you updating your code and also selecting capture properties:

Thanks for your reply, it worked so I guess that it must be a problem of cmake-gui

2012-07-20 10:44:27 -0600 asked a question [GPU] OpenCV 2.4.2 with Cuda support + Ubuntu 12.04 Laptop

I keep getting this error and can't get rid of it:

Linking CXX executable ../../bin/opencv_perf_core
../../lib/libopencv_core.so.2.4.2: undefined reference to `cuDeviceGetAttribute'

I have installed CUDA & CUDA SDK in my ubuntu 12.04 laptop and the cudalibrary and c examples are working perfectly. The problem comes when trying to compile OpenCV 2.4.2 with CUDA=ON.

Any ideas are welcome! Thank you.
