System information (version) OpenCV => 4.1.0 Operating System / Platform => Raspberry Pi 4 / Python 3.7.3 Compiler => cpp Detailed description I am trying to run a python3.7 code with OpenCV 4.1.0 on Raspberry 4 I have OpenCV compiled and installed on RPi4 and tested the version number with cv2.version command.
I get an error when I try to run the Capture Video from Camera sample from https://docs.opencv.org/4.1.0/dd/d43/tutorial_py_video_display.html
The error message is as follows : cv2.error: OpenCV(4.1.0) /home/pi/opencv/modules/highgui/src/window.cpp:627: error: (-2:Unspecified error) The function is not implemented. Rebuild the library with Windows, GTK+ 2.x or Cocoa support. If you are on Ubuntu or Debian, install libgtk2.0-dev and pkg-config, then re-run cmake or configure script in function 'cvShowImage'
There seem to be other similar errors for functions not implemented. Is this something I could fix on my end or is it truly not implemented in 4.1.0
