thank you

Hi, that sends the stream to localhost, on another terminal run python gopro_opencv.py

[mrpiccolo]

thank you for the reply that is a screen of the error i m using ubuntu16.04 and python3 to launch the software

[KonradIT]

something wrong with your OpenCV installation, Google the error.

[mrpiccolo]

Thank you for your reply but the problem isn't opencv, because when i try to capture the frame, it is empty, when i launch gopro_keepalive.py, i receive errors you don't have in your screen

[KonradIT]

In the first terminal everything is in order, problem is opencv
