OrekiCam allows you to put your camera/microphone on pause without any indication to programs utilizing it. As a college student during COVID-19 but a cybersecurity researcher/software engineer first and foremost, I'm apprehensive to install and use any spyware on my computer given the situation. OrekiCam utilizes a forked version of akvcam which I've modified in order to create a separate virtual video capture device that can be paused from OrekiCam.
Install modified akvcam
apt-get update
apt-get upgrade
git clone https://github.com/Ruegg/akvcam
cd akvcam/src
make
make install
depmod -a
Configure the akvcam cameras, /etc/akvcam/config.ini
