Jetson-inference use postnet run rtsp camera, It can be used all the time yesterday, but can't be used when it is started today, why

See this post regarding removing the gstreamer1.0-plugins-ugly package in the event of RTSP authentication errors:

Gst-launch-1.0 rtspsrc

Seems the RTSP server didn’t acknowledge the connection. Is @123 part of the password ? It might not be a good idea to use ‘@’ in password for this case…may require some special string adjustments. Another possible cause of the issue is that in some older gstreamer versions, I remember that something in gstreamer plugins-ugly library could result in authentication failures into RTSP server. If you have this package installed, you may try uninstalling with: sudo apt remove gstreamer1.0-plugi…

If video-viewer and deepstream are still no longer working for RTSP either, you may just want to re-flash your SD card (or use the jetson-inference docker container, which should still be working)

Also you could try running export GST_DEBUG=6 before to see if more information is printed out related to the error.
