I was a bit disappointed as all my 3 USB web cameras did not work with Nano.
They display fine with fswebcam app (but not with Cheese).
I did not want to spend more money to buy a new one.
Anyways… It was hard for me to find a way to use videos files run samples. After some digging I finally put together the following code:
Run run use the command: “python3 mv_detection.py <your_video_file>”
Know bug: If you click over the window while playing the program hangs. Need to kill the process in order to terminate/close it.
