Python rtsp gstCamera

Hello, i’m trying tto use these example : https://github.com/dusty-nv/jetson-inference/blob/master/python/examples/detectnet-camera.py

in Terminal I do :

python3 detectnet-camera.py --camera ‘rtsp://admin:xxx@192.168.0.13:554//h264Preview_01_main’

it fail and give me just few data :

[gstreamer] initialized gstreamer, version 1.14.5.0
[gstreamer] gstCamera::Create(‘rtsp://admin:xxx@192.168.0.13:554//h264Preview_01_main’) – invalid > camera device requested
camera = jetson.utils.gstCamera(opt.width, opt.height, opt.camera)
Exception: jetson.utils – failed to create gstCamera device
PyTensorNet_Dealloc()

I don’t found any explaination for jetson.utils.gstCamera

I’m able to connect and read a frame of my camera with openCV, so the link and the camera are ok.
I’m missing for something.

Thank you !

Hi,
The camera is CSI camera. On Jetson Nano, you can connect Raspberry PI camera V2 and try again.

Hi, what the moderator tried to say is that apparently you can’t use rtsp with that program, just a physical camera connected to the nano. The rtsp part you should do it yourself, but you have many components for that: https://pypi.org/project/rtsp/ is one example.

Best regards.

Hello drakorg and DanrLLL, thabk you for your quick reponse.
I miss that point.
I will try rtsp lib.
I Need to choose the fastest of the 3.
So I will try them.

One last point, is therr any documentation for the jetson library, in particular jetson.utils and jetson.inference ?

Thank you again !
