Introduction

RidgeRun provides an evaluation version of the project, limited to 10 min of execution of web page and ONVIF device support. This evaluation includes all the dependencies in their evaluation version. These dependencies are libonvif and rtsp-sink.

Configure the openssl keys and ONVIF configuration path

To configure the secure connection with the webpage, and allow the project in the mode with webpage support to run, you should create the following directory:

mkidir /usr/share/openssl/

Now you need to copy the key files that were given to you with this project, these are example keys. You can create new keys if you want to.

#give access rights to the directory
sudo chmod -R +777 /usr/share/openssl/
cp cert.crt /usr/share/openssl/
cp key.pem /usr/share/openssl/
cp dhparams.pem /usr/share/openssl/

If you are not running the server as root, you need to give access rights to the directory where the configurations are created:

#in case the directory doesn't exists
mkdir /usr/share/onvif_settings/
sudo chmod +777 -R /usr/share/onvif_settings/

How to run

Arguments

Argument	Values	What it does
interface	Present Network interfaces	This indicates in which network interface the project is going to run, the REST server runs in localhost in the device.
mode	0 for webpage support and 1 for webpage support	Enables or disables the webpage support

Now that the project has been installed, you can run this command to start the ONVIF device

onvif-server-reference-design-0.1.0 --interface wlo1 --mode 1

This command runs the ONVIF server on the interface given, the mode 1 is the one that enables the REST server that can communicate with the webpage. This should be enough to make the server run.

Common Issues

Missing certificates

If the log below appears when running the web server page, that means that certificates are not stored in the correct location.
