  • C920 is good enough for meetings. I solved the focus problem using the traditional Linux method of writing of udev rule which launches a timer when it’s plugged in, which periodically launches a systemd service, which runs a bash script to make sure it self-corrects at least every 5 minutes.

    cat /etc/udev/rules.d/90-video4linux-webcam-config.rules
    KERNEL=="video[0-9]*", SUBSYSTEM=="video4linux", ATTRS{idVendor}=="046d", ATTRS{idProduct}=="0892", TAG+="systemd", RUN{program}="/bin/systemctl start video4linux-webcam-config@$env{MINOR}.timer" ENV{SYSTEMD_WANTS}="video4linux-webcam-config@$env{MINOR}.timer"
    
    ❯ cat /etc/systemd/system/video4linux-webcam-config@.timer
    # This file is managed by ansible-video4linux-webcam-config
    [Unit]
    Description=Periodically restart webcam config service
    
    [Timer]
    # Unit= defaults to service matching .timer name
    OnActiveSec=30
    
    [Install]
    WantedBy=timers.target
    
    ❯ cat /etc/systemd/system/video4linux-webcam-config@.service
    [Unit]
    Description=Set webcam configs
    
    [Service]
    Type=oneshot
    ExecStart=/bin/bash -c "/usr/local/bin/video4linux-webcam-config.sh %I"
    
    [Install]
    WantedBy=multi-user.target
    
    ❯ cat /usr/local/bin/video4linux-webcam-config.sh
    #!/bin/bash
    
    if [[ $# -ne 1 ]]; then
      echo "Expected minor device number as sole argument" 1>&2
      exit 1
    fi
    
       v4l2-ctl -d $1 --set-ctrl focus_automatic_continuous=0
      v4l2-ctl -d $1 --set-ctrl focus_absolute=0
    





  • As someone who has done e-commerce development and supports FLOSS and self-hosting, this is something I would outsource.

    It’s complex, and you can’t really handle payments yourself anyway. That requires certification.

    And people really don’t like it when their e-commerce is down and may able to quantify lost business due to an outage or bug in dollars or sense. It doesn’t feel great to realize something on your end resulted in hundreds of dollars of lost business.

    If the business is very small, places like Shopify have cheap starter tiers.
