Before open an issue here, I tried to solve this problem myself. After quite a thorough googling, I tried :
rm ${HOME}/.cache/gstreamer-1.0/registry.x86_64.bin
debug gstream by :

export GST_DEBUG=WARNING
deepstream-app -c source30_1080p_dec_infer-resnet_tiled_display_int8

It complains:

I run deepstream-test1-app 123.mp4, it comlains:
0:00:00.009463954 416472 0x5635900fa560 WARN GST_ELEMENT_FACTORY gstelementfactory.c:467:gst_element_factory_make: no such element factory “nvv4l2decoder”!

One element could not be created. Exiting.

Seems the nvstreammux thing losts. I asked chatGPT, it says that this thing belongs to DeepStream. How to fix that? All related stupied answers already checked, so forget about it.
As a Linux expert, installing your product wasts me one whole day, what you say?

version-related information are as follows:
└──╼ #deepstream-app --version-all
deepstream-app version 6.3.0
DeepStreamSDK 6.3.0
CUDA Driver Version: 12.0
CUDA Runtime Version: 12.0
TensorRT Version: 8.6
cuDNN Version: 8.9

Dewarper: not found

The version of gstreamer installed in 1.18, not 1.16. DeepStream6.3 requires gstreamer 1.16, it shall be forward-compatible, right?
└──╼ #deepstream-app --gst-version
GStreamer Core Library version 1.18.4
