Hardware gestures (Obsbot Tiny 2 Lite)

• 🖐 open palm — toggle AI face tracking
• ✌️ V sign — toggle zoom tracking
• 🤙 L sign — start/stop zoom in/out

AI tracking is not exposed via V4L2 (proprietary HID). Use the gesture.

Setup files

• /etc/modules-load.d/v4l2loopback.conf — autoload module
• /etc/modprobe.d/v4l2loopback.conf — video_nr=20 card_label=Obsbot4K exclusive_caps=1
• ~/.config/systemd/user/obsbot-cam@.service — templated ffmpeg MJPEG passthrough
• ~/.config/obsbot-cam/<mode>.env — SIZE=... FPS=... per mode
• ~/.config/fish/functions/cam.fish — dispatcher

Add a new mode: create ~/.config/obsbot-cam/<name>.env with SIZE= and FPS=, then add <name> to the modes list in cam.fish.

Manual passthrough (one-off):

ffmpeg -f v4l2 -input_format mjpeg -video_size 3840x2160 -framerate 30 -i /dev/video0 -c:v copy -f v4l2 /dev/video20
