Kamerasau

Stream from Raspberry Camera Module to JSMPEG

Install

Prepare your RaspberrPi with the newest Raspberry Pi OS Lite. Make shure it connects to WiFi and SSH is enabled(by creating a file named ssh in the boot volume, eg. cd /Volumes/boot and touch ssh). Then SSH into your RaspberryPi, update, upgrade and make shure git, ffmpeg and the camera module is installed. Then git clone in pi home directory:

pi@kamerasau1:~ $ git clone git@github.com:martinschilliger/Kamerasau.git
pi@kamerasau1:~ $ cd Kamerasau/
pi@kamerasau1:~/Kamerasau $ sudo chmod +x jsmpeg.sh
pi@kamerasau1:~/Kamerasau $ sudo chmod +x update.sh

Configuration

Copy the configuration file and adjust settings to your need. The example is based on our setting with a RaspberryPi Zero W and a bad network connectivity. If you find optimizations we love to hear from you! 🤗

pi@kamerasau1:~/Kamerasau $ cp example-config.txt kamerasau.conf
pi@kamerasau1:~/Kamerasau $ nano kamerasau.conf

Autostart

Create the service to update the script on startup (simple git pull and set executions rights) and then continuously run it. Based on http://www.diegoacuna.me/how-to-run-a-script-as-a-service-in-raspberry-pi-raspbian-jessie/

Enable and start the services. systemd-networkd-wait-online.service is used to wait for the network before starting to stream. 🤷🏻‍♂️
