camfx

What camfx is

camfx is free Linux software that applies live effects to camera output and sends the result to a V4L2 virtual camera through v4l2loopback and FFmpeg. Effects include background blur or replacement, brightness adjustment, skin smoothing, face-centered framing and experimental eye warping. Users can manage effects through a command-line interface or GTK GUI, combine them, and switch them live through D-Bus.

MediaPipe Tasks supplies segmentation and landmark models; camfx initializes them when needed and caches them locally. Setup requires FFmpeg, the v4l2loopback kernel module, Python 3.12 and a camera exposed as /dev/video*. The project provides installation instructions for a Python virtual environment and a Fedora-focused alpha RPM. That alpha release requires manual v4l2loopback configuration, with packaging automation and split packages deferred. Performance varies with webcam formats, USB bandwidth and the use of machine-learning effects; some webcams cannot maintain 30 FPS at 1080p. camfx is MIT-licensed and intended for Linux users seeking effects through virtual webcam output.

Who it suits

camfx suits Linux users who want to add effects to a camera feed and route it through a virtual webcam. It may fit users comfortable with its listed system prerequisites and, for the alpha RPM, manual v4l2loopback configuration.

Limits

The Fedora-focused alpha RPM requires manual v4l2loopback configuration; packaging automation and split packages are deferred. Performance depends on webcam formats, USB bandwidth and machine-learning effects, and some webcams cannot sustain 30 FPS at 1080p.

Getting started

1. Open the camfx GitHub project page
2. Install FFmpeg, the v4l2loopback kernel module and Python 3.12
3. Connect a camera exposed as /dev/video*
4. Follow the project's Python virtual environment installation instructions or use its Fedora-focused alpha RPM
5. Configure v4l2loopback manually if using the alpha release

Verdict

Choose camfx if you use Linux and want effects routed through a virtual camera, with both command-line and GTK controls. Its free MIT license and live effect switching are useful; look elsewhere if you need an installation without the listed prerequisites or manual alpha-release configuration.
