For future reference:
If you have installed either one of the precompiled distributions opencv-python or opencv-contrib-python from pip there are a few things to note if you are using Linux or macOS (Windows builds have had video support always):
versions < 3.3.1.11 are not compiled with FFmpeg (macOS, Linux) and V4L (webcam support, Linux)
versions >= 3.3.1.11 have been compiled with FFmpeg and V4L
Changelogs are available for every release at the opencv-python package repository https://github.com/skvark/opencv-python/releases.
