pi3-b door viewer setup

readme.md

1. raspbian 32 bit lite, configure ssh/wifi through pi imager.
2. sudo apt-get update && sudo apt-get upgrade && sudo apt-get install vlc git xserver-xorg xinit && sudo mkdir -p /opt/scripts /opt/systemd_services
3. sudo git clone https://github.com/goodtft/LCD-show.git /opt/LCD-show; sudo chmod -R 755 /opt/LCD-show;cd /opt/LCD-show/;sudo ./LCD5-show
   • This gets us the full resolution (800x480) (without this driver, it gets set at 640 instead of 800)
4. modify /boot/config.txt with the following:
   • uncomment dtoverlay=vc4-kms-v3d -- which gets commented by the previous LCD-show scripts. We need this still for libmedia previews to work.
   • add hdmi_blanking=1 to add sleep-like behavior by shutting off hdmi. hopefully works with touch screen.
5. setup systemd service to run rtsp server.
