I am using Ubuntu 16.04 on vm player. I have written a script to connect laptop's webcam. But, I got select timeout error with

ret, frame =

, although I selected camera from "removable devices" section.

When I tried to run script on windows, it was successful.


import numpy as np import cv2

video_capture = cv2.VideoCapture(0)

while(True): ret, frame = cv2.imshow("Frame",frame) if cv2.waitKey(1) & 0xFF == ord('q'): break



error: select timeout select timeout OpenCV Error: Assertion failed (total() == 0 || data != __null) in Mat, file /tmp/binarydeb/ros-kinetic-opencv3-3.3.1/modules/core/include/opencv2/core/mat.inl.hpp, line 500 Traceback (most recent call last): File "", line 9, in <module> ret, frame = cv2.error: /tmp/binarydeb/ros-kinetic-opencv3-3.3.1/modules/core/include/opencv2/core/mat.inl.hpp:500: error: (-215) total() == 0 || data != __null in function Mat

How can I solve it?
