  Fake background for your webcam for use in streaming and video conferencing.
  
  The app provides the ability to either blur your surroundings or replace them with an image of
  your choosing. There is also a feature to apply a Star Wars holograph-syle effect to make it
  appear that you are talking from a galaxy far away. The app will make this cut-out version of your
  Webcam feed available as a second webcam feed to use in any webcam-supporting app such as Zoom or
  Skype - while fakecam is running, simply choose the "Fakecam" video input device in a third-party
  app to use the output of fakecam as your video feed for that app.

  ## v4l2loopback
  
  To use this app you need to install the `v4l2loopback` kernel module. In Debian and Ubuntu
  derivatives this is supplied in the `v4l2loopback-dkms` package in their archives. There is a
  script included at the bottom of this page that you may use to understand the simple steps.
  
  ### Step by step instructions
  
   On Debian and Ubuntu install the package with:
  
      sudo apt install v4l2loopback-dkms
  
  You will also need to configure the kernel module with some non-default options. Do this by adding
  the following line into `/etc/modprobe.d/fakecam.conf` and then run `sudo modprobe -r
  v4l2loopback; sudo modprobe v4l2loopback`:
  
      options v4l2loopback devices=1 video_nr=20 card_label="fakecam" \
      exclusive_caps=1
  
  The kernel module is not loaded at bootup so we also need to add a configuration to make it load
  automatically. On Debian and Ubuntu this is done via adding `v4l2loopback` as a single word on a
  new line in a new file called `/etc/modules-load.d/fakecam.conf`.
  
  ## TL;DR Script for Debian and Ubuntu derivatives
  
      sudo apt-get install v4l2loopback-dkms
      echo options v4l2loopback devices=1 video_nr=20 \
      card_label="fakecam" exclusive_caps=1 | sudo tee -a \
      /etc/modprobe.d/fakecam.conf
      echo v4l2loopback | sudo tee -a /etc/modules-load.d/fakecam.conf
      sudo modprobe -r v4l2loopback
      sudo modprobe v4l2loopback
