Hello.. I want to ask about TensorRT Demos, when I ran the program with the RTSP link.. the output error was like the below..

WARNING:root:Camera: starting while cap is not opened! ERROR: failed to open camera!

Why the program error?

Thank you

Please refer to my blog post: How to Capture and Display Camera Video with Python on Jetson TX2

Make sure you've installed all necessary GStreamer components for RTSP.

@ilhamrayhan117 Try setting USB_GSTREAMER to False to see if it works for you.

hello Jiun,

I have not found a solution for gstreamer rtsp

@Ardihermanto Please refer to https://github.com/jkjung-avt/tensorrt_demos/issues/220 to debug the issue. Basically you need to make sure you could access your RTSP stream by GStreamer first.
