The first few packages, ran this in a file named step1.sh:

sudo apt-get update -y
sudo apt-get upgrade -y
sudo apt-get install python-dev python-pip python-opencv libv4l-dev -y
git clone https://github.com/umlaeute/v4l2loopback
cd v4l2loopback/
make && make install
cd ..
git clone https://github.com/lhelontra/vidcopy
cd vidcopy/
gcc vidcopy.c -o vidcopy
cd ..
echo "v4l2loopback" | sudo tee -a /etc/modules
echo "gc2035" | sudo tee -a /etc/modules
echo "vfe_v4l2" | sudo tee -a /etc/modules

 That will take a while, time for lunch and to start the the next project!
