Prebuilt Binaries Don't Work on v1.0.4: 'cv2.VideoCapture' object has no attribute 'getDevices' #8

Closed flolu closed 2 years ago

flolu commented 2 years ago

Since I wasn't able to build v1.0.4 manually (#7), I'm trying to use the prebuilt binaries. But running the following command

sudo PYTHONPATH="./cv2/" LD_LIBRARY_PATH="./lib/" python3 ~/Downloads/opencv-1.0.4/Source/PythonScript/main.py

inside the ~/Downloads/opencv-1.0.4/Binary/Opencv_4.5.5/Linux/18.04_x64 directory throws the following error:

I made it work by using Ubuntu 20.04 LTS and running

sudo PYTHONPATH="./cv2/" LD_LIBRARY_PATH="./lib/" python3 ~/Downloads/opencv-1.0.4/Source/PythonScript/main.py

inside

~/Downloads/opencv-1.0.4/Binary/Opencv_4.5.5/Linux/20.04_x64
