I couldn't set the asuncio working at Windows 10, but Linux works great. However, the video need h264 library, and installing it to Arch Linux seems to be difficult: see the installing instructions at https://github.com/dji-sdk/Tello-Python/blob/master/Tello_Video/README.md The other method using OpenCV2 is easier to install and set up working.
