New to Python, help with saving image from camera

[ThomasL]

The cv2.imwrite("who.jpg", img) is inside the loop, so every img shown on the screen
is written into that filename. I don´t think that is what you want and i assume the code can´t write that fast.
In addition cv2.imwrite() returns an integer, if i´m not wrong 0 means ok, 1 means error.

Untested and only an idea:

    # Display the resulting frame
    img = cv2.imshow('Server Room', frame)
 
    if cv2.waitKey(1) & 0xFF == ord('q'):
        break
    if cv2.waitKey(1) & 0xFF == ord('p'):
        err = cv2.imwrite("who.jpg", img)
        print(error)
        break

Should save an image if you press p key and then quit.
