Hi, We have deprecated omx plugins. Please use nvv4l2decoder. Here is a python sample for your reference: Doesn't work nvv4l2decoder for decoding RTSP in gstreamer + opencv - #3 by DaneLLL

Also I want to ask, what’s the difference between input the whole gst string into cv2 and use the gi package? are they doing the same thing?

Here’s the updated method for created VideoCapture and VideoWriter: # video capture def _create_jetson_nano_v_cap(self) -> cv2.VideoCapture: gst_str = f"rtspsrc location={self.uri} latency={self.latency} " \ f"! rtph264depay " \ f"! h264parse " \ f"! n…

Try the following sample (assumming that your python install has opencv with Gstreamer support). I just made a localhost RTSP server in a first terminal with test-launch using: ./test-launch "videotestsrc is-live=true ! video/x-raw, width=640, height=480, framerate=30/1 ! nvvidconv ! video/x-raw(m…

Can you share the test-launch shell? and my original code can also work in short period of run. But when comes to keep inferencing frames and recording in about hours, the error is occurred.

Hi,
Please check Jetson Nano FAQ

Q: Is there any example of running RTSP streaming?

And download/build test-launch
