Revision history [back]

I've started my project on Win7 Python3.6 OpenCV 4.1.1.26. The problem is: read() method of capture instance returns zeroes image array and True as retval. But! If i start Videocapture in debug mode - It's works fine! I can see grabbed images!

First of all, I was in doubt of my code. But I've checked example from opencv-python-tutroals. It's same behavior.

I use PyCharm community 2019.2. But checked out from console too: python controller.py - blank screen python -m pdb conftoller.py - works fine.

Does anyone faced with same issue? How to fix it?
