Hi
I post the question below in a wrong place. I post it to here to get your help.
Thanks
Hi,
On Jetson Nano, we support the camera:
You may buy one and try again. You can also try gstreamer pipeline:
$ gst-launch-1.0 nvarguscamerasrc ! nvoverlaysink
Your command “gst-launch-1.0 nvarguscamerasrc ! nvoverlaysink” does not work. The error message as below:
ion@ion-desktop:~$ gst-launch-1.0 nvarguscamerasrc ! nvoverlaysink
Setting pipeline to PAUSED ...
Pipeline is live and does not need PREROLL ...
Setting pipeline to PLAYING ...
New clock: GstSystemClock

This command “gst-launch-1.0 v4l2src device=/dev/video0 ! “video/x-raw, format=(string)UYVY, width=(int)2592,height=(int)1944” ! nvvidconv ! “video/x-raw(memory:NVMM), format=(string)I420” ! nvoverlaysink” is working.
but with the warning message below:

Hi,
Argus works with Bayer sensors. Your camera looks to be this one:
https://www.e-consystems.com/nvidia-cameras/jetson-nano-cameras/5mp-mipi-nano-camera.asp
This is a YUV sensor and should use v4l2src.
Let’s clarify the issue about 12_Ccamera_v4l2_cuda in
Why this WARNING?
How about the camera API libargus, does it only support Bayer sensors camera? Or it does not support YUV sensor camera?
Hi,
Yes, it only supports Bayer sensors. It does not support YUV sensors.
