DeepStream with GigE cameras (Pylon)

Accelerated Computing Intelligent Video Analytics DeepStream SDK
1

Hi, I’m trying to run one of DeepStream-6.1 samples with a Pylon GigE camera as the source.
I followed this link “Quickstart Guide — DeepStream 6.1.1 Release documentation” to install DeepStream and I can successfully run a sample pipeline on one of the prerecorded videos.
I have also Installed a Pylon plugin from “GitHub - joshdoe/gst-plugins-vision: GStreamer plugins related to the field of machine vision” for Gstreamer before, and it works fine.
How can I get the DeepStream to work with the camera now? I want to be able to add the pylonsrc instead of CAmeraV4L2 in the config files:

[source0]
enable=1
#Type - 1=CameraV4L2 2=URI 3=MultiURI
type=1
camera-width=640
camera-height=480
camera-fps-n=30
camera-fps-d=1
camera-v4l2-dev-node=0

• Hardware Platform (Jetson / GPU) NVIDIA GeForce RTX 3070
• DeepStream Version 6.1
• JetPack Version (valid for Jetson only)
• TensorRT Version 8.4.3
• NVIDIA GPU Driver Version (valid for GPU only) 11.7
• Issue Type( questions, new requirements, bugs) questions

deepstream-app is just a sample app, it is totally open source, you can modify the code to add the new source type. Please refer to /opt/nvidia/deepstream/deepstream/sources/apps/

Thank you for your response. Could you please give me a bit more details? I have no idea what to modify and how.
Thank you

Update: I tried this repo (GitHub - NVIDIA-AI-IOT/deepstream-yolo3-gige-apps: A project demonstration on how to use the GigE camera to do the DeepStream Yolo3 object detection, how to set up the GigE camera, and deployment for the DeepStream apps. · GitHub) to write an app that works with GigE cameras, it uses Aravis plugin for GigE cameras and the plugin works with GStreamer however I get the following error with both plugins (Aravis and the one here GitHub - joshdoe/gst-plugins-vision: GStreamer plugins related to the field of machine vision · GitHub):

Could not create 'src_elem'
Failed to create source bin. Exiting

The following lines cause this error:

  //create a source for ARAVIS SDK
  GstElement *src_elem = gst_element_factory_make ("aravissrc", "src_elem");
  if (!src_elem)
  {
    g_printerr ("Could not create 'src_elem'\n");
    return NULL;
  }

I found another topic with the exact same problem:

There is no update from you for a period, assuming this is not an issue anymore.
Hence we are closing this topic. If need further support, please open a new one.
Thanks

How much do you know about gstreamer?( GStreamer: open source multimedia framework). It is just to add a new source which is a very common gstreamer usage.
joshdoe/gst-plugins-vision: GStreamer plugins related to the field of machine vision (github.com) is third party open source projects, please ask the owner for help.
