Deepstream Setup

This post assumes you have a fully functional Jetson device. If not, you can refer the documentation here.

1. Install System Dependencies

sudo apt install \
libssl1.0.0 \
libgstreamer1.0-0 \
gstreamer1.0-tools \
gstreamer1.0-plugins-good \
gstreamer1.0-plugins-bad \
gstreamer1.0-plugins-ugly \
gstreamer1.0-libav \
libgstrtspserver-1.0-0 \
libjansson4=2.11-1

2. Install Deepstream

Download the DeepStream 5.1 Jetson Debian package deepstream-5.1_5.1.0-1_arm64.deb, to the Jetson device from here. Then enter the command:

sudo apt install deepstream-5.1_5.1.0-1_arm64.deb

For more information, go to the get started page of Deepstream here.

Running the Application

1. Clone the repository

This is a straightforward step, however, if you are new to git, I recommend glancing threw the steps.

First, install git

sudo apt install git

Next, clone the repository

# Using HTTPS
https://github.com/aj-ames/YOLOv4-Deepstream.git
# Using SSH
git@github.com:aj-ames/YOLOv4-Deepstream.git

2. Download the weights file

Download the weights file from google-drive and place it in models/YOLOv4 directory.

3. Build the application

First, build the application by running the following command:

make clean && make -j$(nproc)

This will generate the binary called ds-yolo. This is a one-time step and you need to do this only when you make source-code changes.

4. Run with different input sources

Next, create a file called inputsources.txt and paste the path of videos or rtsp url.

file:///home/astr1x/Videos/sample.mp4
rtsp://admin:admin%40123@192.168.1.1:554/stream

Now, run the application by running the following command:

./ds-yolo
