Simple background blur for your webcam.

This script will capture your webcams output, add a blur effect to the background and output the generated image to another (virtual) video device.

python -m venv venv
source venv/bin/activate

pip install -r requirements.txt

sudo modprobe v4l2loopback exclusive_caps=1 devices=1 video_nr=20 card_label=backgroundblur

There should now be a new video device under /dev/video20.

./blur.py --input /dev/video0 --output /dev/video20

Tested with python 3.9.7
