The question of turn on the camera

Autonomous Machines Jetson & Embedded Systems Jetson TX2

In order to turn on the camera , I used the following command :

gst-launch-1.0 nvcamerasrc ! 'video/x-raw(memory:NVMM), width=(int)1920, height=(int)1080, format=(string)I420, framerate=(fraction)60/1' ! nvvidconv ! 'video/x-raw(memory:NVMM), format=(string)I420' ! nvoverlaysink -e

It has a error and the camera dosn’t turn on:

WARNING: erroneous pipeline: no element "nvcamerasrc"

But if I use the command “nvgstcapture-1.0” ,the camera turn on successfully .

My gst-launch-1.0 version is 1.14.5 .

hello arknights,

may I know which JetPack release you’re working with.
please also refer to Development Guide, you should using nvarguscamerasrc plugin instead.
thanks

It is JetPack 4.2.1(rev.1)

nvcamerasrc has already deprecated, please using nvarguscamerasrc instead.

Hello JerryChang,

Thanks ,the camera turns on.
I have another question about L4T Multimedia,
in this sample application:
https://docs.nvidia.com/jetson/archives/l4t-multimedia-archived/l4t-multimedia-322/l4t_mm_camcap_tensorrt_multichannel_group.html
I can run it successfully , but I can’t find three output files(output1.h265 , output2.h265 , output3.h265) .
I also found that the sample 09_camera_jpeg_capture and the sample 10_camera_recording have the same problem .
How can I view all of its output ?
