That error means the version of OpenCV you imported was not built with CUDA, can you check that you are importing the version of OpenCV you built by checking the result of

print(cv2.getBuildInformation())

Apologies I should have read your initial post more clearly. You haven't compiled against the Nvidia Video Codec SDK.

Installation instructions can be found under item (5) from Build OpenCV (including Python) with CUDA on Windows.
