Watch: How to Run Multiple Streams with DeepStream SDK on Jetson Nano using Ultralytics YOLO11

This comprehensive guide provides a detailed walkthrough for deploying Ultralytics YOLO11 on NVIDIA Jetson devices using DeepStream SDK and TensorRT. Here we use TensorRT to maximize the inference performance on the Jetson platform.

DeepStream on NVIDIA Jetson

!!! note

This guide has been tested with both [Seeed Studio reComputer J4012](https://www.seeedstudio.com/reComputer-J4012-p-5586.html) which is based on NVIDIA Jetson Orin NX 16GB running JetPack release of [JP5.1.3](https://developer.nvidia.com/embedded/jetpack-sdk-513) and [Seeed Studio reComputer J1020 v2](https://www.seeedstudio.com/reComputer-J1020-v2-p-5498.html) which is based on NVIDIA Jetson Nano 4GB running JetPack release of [JP4.6.4](https://developer.nvidia.com/jetpack-sdk-464). It is expected to work across all the NVIDIA Jetson hardware lineup including latest and legacy.

What is NVIDIA DeepStream?#

NVIDIA’s DeepStream SDK is a complete streaming analytics toolkit based on GStreamer for AI-based multi-sensor processing, video, audio, and image understanding. It’s ideal for vision AI developers, software partners, startups, and OEMs building IVA (Intelligent Video Analytics) apps and services. You can now create stream-processing pipelines that incorporate neural networks and other complex processing tasks like tracking, video encoding/decoding, and video rendering. These pipelines enable real-time analytics on video, image, and sensor data. DeepStream’s multi-platform support gives you a faster, easier way to develop vision AI applications and services on-premise, at the edge, and in the cloud.

Prerequisites#

Before you start to follow this guide:

!!! tip

In this guide we have used the Debian package method of installing DeepStream SDK to the Jetson device. You can also visit the [DeepStream SDK on Jetson (Archived)](https://developer.nvidia.com/embedded/deepstream-on-jetson-downloads-archived) to access legacy versions of DeepStream.

DeepStream Configuration for YOLO11#

Here we are using marcoslucianops/DeepStream-Yolo GitHub repository which includes NVIDIA DeepStream SDK support for YOLO models. We appreciate the efforts of marcoslucianops for his contributions!

  1. Install dependencies

    pip install cmake
    pip install onnxsim
    
  2. Clone the following repository

    git clone https://github.com/marcoslucianops/DeepStream-Yolo
    cd DeepStream-Yolo
    
  3. Download Ultralytics YOLO11 detection model (.pt) of your choice from YOLO11 releases. Here we use yolov8s.pt.

    wget https://github.com/ultralytics/assets/releases/download/v8.2.0/yolov8s.pt
    

    !!! note

    You can also use a [custom trained YOLO11 model](https://docs.ultralytics.com/modes/train/).
    
  4. Convert model to ONNX

    python3 utils/export_yoloV8.py -w yolov8s.pt
    

    !!! note “Pass the below arguments to the above command”

    For DeepStream 6.0.1, use opset 12 or lower. The default opset is 16.
    
    ```bash
    --opset 12
    ```
    
    To change the inference size (default: 640)
    
    ```bash
    -s SIZE
    --size SIZE
    -s HEIGHT WIDTH
    --size HEIGHT WIDTH
    ```
    
    Example for 1280:
    
    ```bash
    -s 1280
    or
    -s 1280 1280
    ```
    
    To simplify the ONNX model (DeepStream >= 6.0)
    
    ```bash
    --simplify
    ```
    
    To use dynamic batch-size (DeepStream >= 6.1)
    
    ```bash
    --dynamic
    ```
    
    To use static batch-size (example for batch-size = 4)
    
    ```bash
    --batch 4
    ```
    
  5. Set the CUDA version according to the JetPack version installed

    For JetPack 4.6.4:

    export CUDA_VER=10.2
    

    For JetPack 5.1.3:

    export CUDA_VER=11.4
    
  6. Compile the library

    make -C nvdsinfer_custom_impl_Yolo clean && make -C nvdsinfer_custom_impl_Yolo
    
  7. Edit the config_infer_primary_yoloV8.txt file according to your model (for YOLOv8s with 80 classes)

    [property]
    ...
    onnx-file=yolov8s.onnx
    ...
    num-detected-classes=80
    ...
    
  8. Edit the deepstream_app_config file

    ...
    [primary-gie]
    ...
    config-file=config_infer_primary_yoloV8.txt
    
  9. You can also change the video source in deepstream_app_config file. Here a default video file is loaded

    ...
    [source0]
    ...
    uri=file:///opt/nvidia/deepstream/deepstream/samples/streams/sample_1080p_h264.mp4
    

Run Inference#

deepstream-app -c deepstream_app_config.txt

!!! note

It will take a long time to generate the TensorRT engine file before starting the inference. So please be patient.
YOLO11 with deepstream

!!! tip

If you want to convert the model to FP16 [precision](https://www.ultralytics.com/glossary/precision), simply set `model-engine-file=model_b1_gpu0_fp16.engine` and `network-mode=2` inside `config_infer_primary_yoloV8.txt`

INT8 Calibration#

If you want to use INT8 precision for inference, you need to follow the steps below

  1. Set OPENCV environment variable

    export OPENCV=1
    
  2. Compile the library

    make -C nvdsinfer_custom_impl_Yolo clean && make -C nvdsinfer_custom_impl_Yolo
    
  3. For COCO dataset, download the val2017, extract, and move to DeepStream-Yolo folder

  4. Make a new directory for calibration images

    mkdir calibration
    
  5. Run the following to select 1000 random images from COCO dataset to run calibration

    for jpg in $(ls -1 val2017/*.jpg | sort -R | head -1000); do \
        cp ${jpg} calibration/; \
    done
    

    !!! note

    NVIDIA recommends at least 500 images to get a good [accuracy](https://www.ultralytics.com/glossary/accuracy). On this example, 1000 images are chosen to get better accuracy (more images = more accuracy). You can set it from **head -1000**. For example, for 2000 images, **head -2000**. This process can take a long time.
    
  6. Create the calibration.txt file with all selected images

    realpath calibration/*jpg > calibration.txt
    
  7. Set environment variables

    export INT8_CALIB_IMG_PATH=calibration.txt
    export INT8_CALIB_BATCH_SIZE=1
    

    !!! note

    Higher INT8_CALIB_BATCH_SIZE values will result in more accuracy and faster calibration speed. Set it according to you GPU memory.
    
  8. Update the config_infer_primary_yoloV8.txt file

    From

    ...
    model-engine-file=model_b1_gpu0_fp32.engine
    #int8-calib-file=calib.table
    ...
    network-mode=0
    ...
    

    To

    ...
    model-engine-file=model_b1_gpu0_int8.engine
    int8-calib-file=calib.table
    ...
    network-mode=1
    ...
    

Run Inference#

deepstream-app -c deepstream_app_config.txt

MultiStream Setup#

To set up multiple streams under a single deepstream application, you can do the following changes to the deepstream_app_config.txt file

  1. Change the rows and columns to build a grid display according to the number of streams you want to have. For example, for 4 streams, we can add 2 rows and 2 columns.

    [tiled-display]
    rows=2
    columns=2
    
  2. Set num-sources=4 and add uri of all the 4 streams

    [source0]
    enable=1
    type=3
    uri=<path_to_video>
    uri=<path_to_video>
    uri=<path_to_video>
    uri=<path_to_video>
    num-sources=4
    

Run Inference#

deepstream-app -c deepstream_app_config.txt
