Hello, I am trying to take a 3840*2160 60fps rtsp stream on jetson nano Nx 16GB as the input for deepstream sample app, with jetson clocks running and NV power MAXN. And the test app /opt/nvidia/deepstream/deepstream/samples/configs/deepstream-app/source1_usb_dec_infer_resnet_int8.txt:

1. I have modified the input into:

[source0]
enable=1
type=4
uri=rtsp://admin:123456@192.168.1.100:8554/live

2. 3840*2160 60fps rtsp input, but the fps output on the terminal is only about around 42 fps, and the display video blurs in the rapidly changing video regions.
3. Then I tried to slow down the input fps to 30, the deepstream processing fps is stable around 30, but the video blurring does not improve.
4. Then I tried input of 1920*1080 60/30 fps rtsp input, everything went ok and no blurring and fps is the same as the input.
5. I also tried to view the same 4k rtsp input by the VLC player, no blurring happens.
   So the question is how to avoid the blurring and the lower fps with the 4K 60fps rtsp input? Is there any parameters or setting I can set or this is only the performance limit of the orin Nx hardware?
   Thanks for your help.

1. You can use tegrastats to check the loading of your board
2. Could you try to use videotestsrc to reproduce your problem?

gst-launch-1.0 -v videotestsrc ! video/x-raw,format=<your_camera_format>, width=3840,height=2160,framerate=30/1 ! ...
