Opencv Rtsp Stream timeout - Python - OpenCV
I have an RTSP URL for streaming from a CCTV camera, but I get the following error: [ WARN:[email protected]] global cap_ffmpeg_impl.hpp:453 _opencv_ffmpeg_interrupt_callback Stream timeout triggered after 30046.359055 ms When I test the same URL in VLC by opening the network stream, the live feed works perfectly. What could be causing this issue, and how can I fix it?

Error: OpenCV(4.11.0) error: (-5:Bad argument) in function 'imshow'
I think there was an update to the input sent to opencv in version 4.11 and it especially affects Linux-based systems. The question is, how should we adjust the array inputs created with numpy in Linux-based systems in the current version?

DLL load failed while importing cv2 - Python - OpenCV
I may be wrong but it seems like you are mixing up two different installation methods. If you pip install you shouldn’t need to copy any dll’s accross. If you are building from scratch then don’t pip install (pip uninstall any existing OpenCV installation first ) and read ImportError: DLL load failed while importing cv2: The specified module could not be found to see if it helps.

Missing opencv dlls - OpenCV
OpenCV has, or is in the process of gaining, a kind of runtime dispatch for some of its backends (highgui, videoio). What you’re seeing is its thought process. It will look for stuff that might be available, and if it isn’t, that’s fine. I think you can modulate the verbosity of this. I don’t know off the top of my head.
