Instructions for creating a fake webcam

1. Install v4l2loopback (AUR package v4l2loopback-dkms)
   • Make sure you have linux-headers installed
2. Create the fake camera device
   • sudo modprobe v4l2loopback exclusive_caps=1 card_label=FakeWebcam
   • To load the module on boot create /etc/modules-load.d/v4l2loopback.conf v4l2loopback
   • Options are placed in /etc/modprobe.d/v4l2loopback.conf options v4l2loopback exclusive_caps=1 card_label=FakeCamera
3. v4l2-ctl --list-devices shows you which /dev/videoX is the fake camera and which are real cameras
4. Run video_loop input_video output_device
5. Run ffplay output_device to verify that it is working
6. Run video_record output_file input_device to record a video from the webcamera.
