By switching from hc to hap, I was able to clean up some code.

This version was tested on macOS Big Sur 11.3.1 (20E241) and on a Raspberry Pi running Raspberry Pi OS 32-bit (Kernel version: 5.10, Debian version: 11 (bullseye)). On macOS I've used the built-in iSight camera. On the Raspberry Pi I was able to get it to work with a USB camera (ELP 1080P) and a standard camera module. (The camera module requires Legacy Camera Support though.)

There is currently no pre-configured Raspberry Pi image available because installing v4l2loopback and ffmpeg is easy to install via apt-get (see Readme).

This release improves the video stream quality by setting the video resolution to 720p and providing an option to set the minimum video bit rate.

The pre-configured Raspbian image sets the video resolution via v4l2-ctl in the /etc/sv/hkcam/run script.
The minimum bit rate is not specified but you can set it with the --min_video_bitrate argument.

A run script with a minimum bit rate of 500kbps might look like this

#!/bin/sh -e
exec 2>&1
v4l2-ctl --set-fmt-video=width=1280,height=720,pixelformat=YU12
exec hkcam --min_video_bitrate=500 --data_dir=/var/lib/hkcam/data --verbose=true

Note: Setting a minimum video bitrate might break streaming to Apple Watch.
