CSI camera with python apps

Please provide complete information as applicable to your setup.

• Hardware Platform (Jetson / GPU)
Jetson Nano 4GB, camera: Arducam IMX 519.
• DeepStream Version
6.0
• JetPack Version (valid for Jetson only)
4.6.0,4.61,4.6.2
• TensorRT Version
• NVIDIA GPU Driver Version (valid for GPU only)
• Issue Type( questions, new requirements, bugs)
question
• How to reproduce the issue ? (This is for bugs. Including which sample app is using, the configuration files content, the command line used and other details for reproducing)
I just run python app example and got this error, don’t know why. DeepStream c api works well. But python bindings cannot run with saved video with my custom code and its CSI or USB camera app.
Here is the o/p:

edit:
I tried this solution in the same app but got this o/p:

/opt/nvidia/deepstream/deepstream-6.0/sources/deepstream_python_apps/apps/deepstream-test1-usbcam$ python3 deepstream_test_1_usb.py /dev/video0

Traceback (most recent call last):
  File "deepstream_test_1_usb.py", line 280, in <module>
    sys.exit(main(sys.argv))
  File "deepstream_test_1_usb.py", line 212, in main
    source.set_property('device', args[1])
TypeError: object of type `GstNvArgusCameraSrc' does not have property `device'

deepstream_test_1_usb.py is used for v4l2src and argus camera is for special interface.
pls don’t use the solution

you can try this solution for the deepstream_test_1_usb.py

It looks like the steam format of v4l2src is not supported

If native code works well,Can you provide the sample code of the c api?

I use this solution with this code copying the sgie and pgie files of the this folder to this.

can you share the sample code which you are currently using
and what type of camera are you currently using ? usb or argus

the nvarguscamerasrc don’t support the device property,it’s only for v4l2src
you can got the properties use
gst-inspect-1.0 nvarguscamerasrc

and you can try
gst-launch-1.0 nvarguscamerasrc ! nvv4l2h264enc ! queue ! filesink location=out.h264
make sure the argus camera can work fine

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
