I got the same error. There could be two reasons,
Solution:
cv2 doesn't compile with FFmpeg be default. Pip uninstall Opencv and follow the steps mentioned in this link
http://www.wiomax.com/compile-opencv-and-ffmpeg-on-ubuntu/
verify if the webcam has a device ID 0.
Hope this helps.

Thank you for your response, visionanand. The instruction in that link does not work for me, there are several errors when I tried those commands. It probably because i am using Ubuntu 16. I will give it another try sometime tomorrow then

The problem is simple the image format is in RGBA, so convert the image to RGB it works for me
