I had change the deepstream_sdk_v4.0_jetson\sources\apps\apps-common\src\deepstream_source_bin.c file code to the pipeline which it suggested like as jhchris713 post# 7 from How to change source pixel format from YUYV to MJPG.
I rebuilt it which you suggested like as post# 9 from How to change source pixel format from YUYV to MJPG.
my computer environment:
Jetson Nano
deepstream_sdk_v4.0.2
my camera information:

unexpectedly, I had error with deepstream-app like below:
