Keep your webcam focused
This app/service monitors for your webcam to be in use and when found to be in use it'll run a command to tell your camera to refocus on a given interval.
I use a Logitech webcam with Ubuntu and while it works quite well, it can lose focus if I move around much and
fail to refocus on its own. Using the v4l2-ctl utility the camera can be told to refocus. I've been using that
manually during meetings when my camera gets unfocused and finally decided to write a systemd service to do
that automatically for me.
stay-focused will either monitor for a specific process to be running or a specific module to be in use. The
default is to look for the module uvcvideo to be in use. When either the given process or module is detected
to be in use, stay-focused will run the given command to tell your camera to refocus. The interval in which
checks for camera use is configurable as well as how frequently the camera is told to refocus while the camera
is in use.
- Camera in use checks: Every 1 minute
- Refocus calls while camera is in use: Every 10 seconds
- Camera device: /dev/video0
- Module to check for use:
uvcvideo
