PTZ Microservice allows you to navigate a video through PTZ.

It leverages the RidgeRun Spherical Video PTZ to make possible the selection of your region of interest within the sphere. This is specified through pan (horizontal), tilt (vertical), and zoom controls, which can be updated at any time during execution.

This service receives an RTSP stream, performs the PTZ depending on the user instructions, and then returns the stream using the same protocol, RTSP.

API configuration

Take a look at the API Documentation for a list of the available requests.

Running the service

Before running the service, you should make sure you have all the dependencies installed. The intructions to do it can be found here: Spherical Video PTZ Building and Installation

Then you have to clone into your device the repository project, available [ https://gitlab.ridgerun.com/ridgerun/rnd/jetson-microservices-and-genai/ptz | here ]

The project is configured (via setup.py) to install the service with the name ptz. So to install it run:

pip install .

Then you will have the service with the following options:

usage: ptz [-h] [--port PORT] [--host HOST]

options:
 -h, --help   show this help message and exit
 --port PORT  Port for server
 --host HOST  Server ip address

PTZ Microservice Docker

Before starting with docker support make sure you have nvidia runtime in your system. Follow | these instructions to have docker up and runing in your Jetson Board.

Build the container

We can build the ptz microservice container using the Dockerfile in the docker directory. This includes a base NVIDA image and the dependencies to run the ptz microservice application.

First, we need to prepare the context directory for this build, please create a directory and include all the needed repositories (listed below). The Dockerfile will look for all the source code in the context directory and copy them to the container.

ptz-context/
.
├── gst-cuda
├── gst-rr-panoramaptz
├── gst-rtsp-sink
├── libpanorama
├── ptz
└── rrms-utils

Then build the container image running the the following command from the folder containing the Dockerfile and context directory:

sudo docker build \
--network=host \
-f Dockerfile \
-t ridgerun/ptz-service:latest ptz-context/

Change ptz-context to your context's path and the tag (-t) to the name you want to give to your image.

Launch the container

The container can be launched by running the following command:

sudo docker run --runtime nvidia -it --privileged --net=host --ipc=host --name ptz-service  ridgerun/ptz-service:latest

You can modify the name you want to give to your container with the option --name.

Here we are creating a container called ptz-service that will start the ptz-service application in the default address and path. If a different address and port have to be used, you can do it by running:

sudo docker run --runtime nvidia -it --privileged --net=host --ipc=host --name ptz-service  ridgerun/ptz-service:latest --host=HOST --port=PORT
