How to apply the DeepStream to the cameras with the GigE Vision protocol

Hello,
I would like to use a camera with the GigE Vision protocol (i.e. Basler acA 1920-40gc) for the object detection based on DeepStream and YOLOv3. At present, the camera runs on the Jetson AGX Xavier.

I wonder how to modify the file deepstream_app_config_yoloV3.txt so that the data of the camera can be used as the input data of the DeepStream. The following configuration cannot ensure that the camera operates in the DeepStream:

 [source0]
  enable=1
  #Type - 1=CameraV4L2 2=URI 3=MultiURI
  type=3
  #uri=file://../../samples/streams/sample_1080p_h264.mp4
   uri=udp://219.216.101.5
   num-sources=1
   gpu-id=0
  # (0): memtype_device   - Memory type Device
  # (1): memtype_pinned   - Memory type Host Pinned
  # (2): memtype_unified  - Memory type Unified
  cudadec-memtype=0

Any helps is welcomed.

Can you play the camera stream by “gst-launch-1.0” firstly ?
