Hi,
Seems like software decoder is absent in your environment. Please try hardware decoder:
DISPLAY=:1 gst-launch-1.0 v4l2src device=/dev/video0 ! video/x-h264,width=2560,height=720,framerate=30/1 ! h264parse ! nvv4l2decoder ! nvegltransform ! nveglglessink sync=0
front usb camera device report the error as log.txt

rear nvidia device as the follow：
Hi,
It looks like hardware decoder cannot decode the stream. Please check if the camera supports other formats such as YUV422.
support yuv420
What command is used to display YUV?
Hi,
Please refer to
Using gst-launch-1.0 pipeline to Receiving (on target) : Network Source + video decode + video render - #14 by DaneLLL
The guidance is in FAQ.
Please run the command and share the prints for reference:
$ v4l2-ctl -d /dev/video0 --list-formats-ext
