processor.listenToKeyboardEvents(); in Main.cpp has no function

[tim9510019]

I can't press space to pause the frame.
Nor can I stop close the window with ESC.

You probably are using a different OS or keyboard setup that's not giving the correct key for space.

vivaTracker/vivalib/utils.cpp

Line 39 in baf0a99

const int Keys::ESC = 27;

Check documentation for opencv's waitKey

Thanks for your advices.
I ran VM for Ubuntu 16.04, and I modified line 207 in viva.cpp:
key = waitKey(1) & 0xff;

The Keyboard function worked.
