Hi, I have this issue when running "video_demo.py " can somebody help?

I've already tried below, but didn't work.

1. "sudo apt install ubuntu-restricted-extras'
2. sudo apt install gstreamer1.0-plugins-good/bad/ugly
3. pip install pyqt5

OS: Linux-5.4.0-121-generic-x86_64-with-debian-buster-sid'

Let me know if you find a solution, so I can update the FAQ.
