Camera can not work with gstreamer

[meng.li]

Hi Expert,

I download Jetson_Linux_r36.4.3_aarch64.tbz2 https://developer.nvidia.com/downloads/embedded/l4t/r36_release_v4.3/release/Jetson_Linux_r36.4.3_aarch64.tbz2
And then burn orin nx with below command
sudo ./tools/kernel_flash/l4t_initrd_flash.sh --external-device nvme0n1p1 -c tools/kernel_flash/flash_l4t_t234_nvme.xml -p “-c bootloader/generic/cfg/flash_t234_qspi.xml” --showlogs --network usb0 p3768-0000-p3767-0000-a0-nvme external

and then I follow Accelerated GStreamer — Jetson Linux<br/>Developer Guide 34.1 documentation to test camera, but encounter below error

gst-launch-1.0 nvarguscamerasrc ! 'video/x-raw(memory:NVMM), \

I try another command, still have stranger issue
mli1@mli1-desktop:~$ gst-launch-1.0 nvv4l2camerasrc device=/dev/video0 ! \

another question,
How can I confirm which sink is used?

thanks,

I use below simple command, but still report error.

gst-launch-1.0 v4l2src device=/dev/video0 ! ‘video/x-raw, format=(string)NV12, width=(int)1920, height=(int)1080, framerate=(fraction)30/1’ ! nveglglessink -e

hello meng.li,

let’s narrow down this issue
(1) is the camera device register to system correctly?
please check kernel init message, such as.. $ dmesg > klogs.txt
it should reported as following..

[   10.172978] imx185 9-001a: probing v4l2 sensor
[   10.173155] imx185 9-001a: tegracam sensor driver:imx185_v2.0.6
[   10.175734] tegra-camrtc-capture-vi tegra-capture-vi: subdev imx185 9-001a bound
[   10.179580] imx185 9-001a: Detected IMX185 sensor

(2) please check you’ve video node availabe, $ ls /dev/video0, please also run.. $ v4l2-ctl -d /dev/video0 --list-formats-ext to check the sensor format dumps.

(3) you may see-also applications Using V4L2 IOCTL Directly to use V4L2 IOCTL to verify basic functionality.
for instance, $ v4l2-ctl -d /dev/video0 --set-fmt-video=width=1920,height=1080,pixelformat=RG10 --set-ctrl bypass_mode=0 --stream-mmap --stream-count=100

thanks a lot!
I have resolved this issue.
