This fork of Kitty allows feeding the terminal to V4L2 Loopback device.
Example:
sudo modprobe v4l2loopback devices=1
sudo v4l2loopback-ctl set-caps "video/x-raw,format=RGB,width=3200,height=1800" /dev/video*
v4l2loopback-ctl set-fps 5 /dev/video*
kitty/launcher/kitty --v4l2_res 3200x1800 --v4l2_dev /dev/video*
, where video* is for example video1. If v4l2 mode is set, the window size is fixed, chnage the width and height both in the v4l2loopback-ctl and in --v4l2_res to your liking, they need to be the same though.
The recorded feed might be upside down to to OpenGL.
