I have built OpenCV 3.0 with CUDA 7.0 using Visual Studio 2013 x64. When running the VideoReader example I get the following error:

OpenCV Error: The function/feature is not implemented (The called functionality is disabled for current build or platform) in throw_no_cuda, file D:\Dokumente\opencv-master\modules\core\include\opencv2/core/private.cuda.hpp, line 101

I can't figure out what's the problem. Might this be a bug or did I miss something?

I finally made it work by using an old driver version for my Geforce 750 TI. I used Geforce 337.88 as this is the latest version that supports NVCUVENC. The latest CUDA Toolkit version supporting NVCUVENC is 5.5 so I used this one. Although the CUDA Toolkit installation wizard said my device isn't supported, it worked. I built OpenCV 3.0 with Visual Studio 2010 (2013 didn't work) on x64.

Did you specify WITH_NVCUVID in CMake?
If you use cudacodec module, you need to specify this option in CMake.

But, I can not find NVCUVENC in NVIDIA CUDA Toolkit v7.0.
So, I disabled encoding feature of cudacodec
I wrote a method to use decoding feature of cudacodec in my webpage(Content is Japanese).

Thanks but this wouldn't solve my problem as I need encoding features. Actually you gave me the right hint. The problem is NVCUVENC and I solved the problem myself. I will post the solution later.

hi Averius, I am also facing the same problem with CUDA 8 and opencv 3.2 in ubuntu 16.04. Can you share your solution to this problem?
