Existing HN: Blur Webcam Background on Linux

webcam-filters

Add filters (background blur, etc) to your webcam on Linux.

Video conferencing purposes are more likely to both lack video effects altogether or
toughen handiest a cramped situation of capabilities on Linux (e.g. Zoom, Google Meets).

Purpose right here is to perform a virtual webcam by the command of v4l2loopback with a abnormal
situation of filters that will perhaps well well even be frail in each keep.

Usage

Passthrough (no-op):

$ webcam-filters --input-dev /dev/video0 --output-dev /dev/video3

Blur background:

$ webcam-filters --input-dev /dev/video0 --output-dev /dev/video3 --background-blur 150

Dependencies

Diverse than the Python dependencies that will perhaps well well even be mechanically installed by Pip,
there are a few map dependencies that require manual attention.

v4l2loopback

v4l2loopback kernel module is required to emulate a virtual webcam. Glance your
distro’s medical doctors or v4l2loopback on how one can set up and situation it up
(e.g. https://archlinux.org/programs/community/any/v4l2loopback-dkms/).

You are going to likely want to perform as a minimal one loopback tool (that’s persistent
on boot):

$ sudo tee /etc/modprobe.d/v4l2loopback.conf << "EOF"
# /dev/video3
alternatives v4l2loopback video_nr=3
alternatives v4l2loopback card_label="Digital Webcam"
alternatives v4l2loopback exclusive_caps=1
EOF
$ sudo modprobe v4l2loopback
$ v4l2-ctl --tool /dev/video3 --info

Gstreamer

gstreamer-1.0 (e.g. https://archlinux.org/programs/extra/x86_64/gstreamer/)
gst-plugins-snide (e.g. https://archlinux.org/programs/extra/x86_64/gst-plugins-snide/)
gst-python (e.g. https://archlinux.org/programs/extra/x86_64/gst-python/)

Set up

You are going so that you just would possibly both command pipx or pip. Pipx is counsel to retain dependencies
isolated.

Latest steady:

$ pipx set up --map-residing-programs webcam-filters
$ pip set up --person webcam-filters

Latest pre-release:

$ pipx set up --map-residing-programs --pip-args='--pre' webcam-filters
$ pip set up --person --pre webcam-filters
