hello, I spend much time compiling opencv3.1/3.2 on ubun16.04,cuda8,python2.7, but still failed, and it shows error:

how to fix it? can you give some advises? thnak you very much~

hello, I have one code: import cv2 cv2.VideoCapture(xxx.mp4/avi) print vidcap.isOpened() it still is False. I google for much time and rebuild ffmpeg and opencv. It they do not work. anyone can give some advises? I use ubuntu16.04 anaconda2 thank you very much~~

besides, I have python-opencv3.2 for python, but I install opencv2.4.13 from source. So must I install opencv3.2 from source?
