Deepstream python app test-3 cannot decode rtsp stream

Hello,
I had a problem about rtsp stream, i wonder can you give some advice, thanks.
Actually Deepstream python app test-3 works well with local files h264, but cannot decode rtsp stream, I generated rtsp stream by a usb camera with obs on another computer… I got the errors as below when I run
deepstream_test_3.py:

GST_DEBUG=3 python3 deepstream_test_3.py rtsp://user:password@ipaddress:554/live

Actually now test-3 works well with public rtsp stream like below:

GST_DEBUG=3 python3 deepstream_test_3.py rtsp://wowzaec2demo.streamlock.net/vod/mp4:BigBuckBunny_115k.mov

But still not working with my own rtsp stream generated from my laptop camera with obs rtsp server: GST_DEBUG=3 python3 deepstream_test_3.py rtsp://ipaddress:8554/live, the errors as as below…
do not know why this happens, thanks!

And after the above errors, there are huge of messy letters and number coming up…

The rtsp seems not standard RFC 2326 stream. Please contact the camera vendor.
