The environment is agx-orin, Jetpack version 5.0.1.
I use a mipi csi camera with UYVY output. The driver has been debugged properly.
The following command will preview the camera image normally.
export DISPLAY=:1
gst-launch-1.0 v4l2src device=/dev/video0 ! "video/x-raw,format=(string)UYVY,width=(int)1920, height=(int)1080" ! nvvidconv ! "video/x-raw(memory:NVMM),format=(string)NV12" ! nv3dsink -e
But error occurred if I use nvv4l2camerasrc:
export DISPLAY=:1
gst-launch-1.0 nvv4l2camerasrc device=/dev/video0 ! "video/x-raw(memory:NVMM),format=(string)UYVY,width=(int)1920, height=(int)1080" ! nvvidconv ! "video/x-raw(memory:NVMM),format=(string)NV12" ! nv3dsink -e
Here is error log:
$ gst-launch-1.0 nvv4l2camerasrc device=/dev/video0 ! "video/x-raw(memory:NVMM),format=(string)UYVY,width=(int)1920, height=(int)1080" ! nvvidconv ! "video/x-raw(memory:NVMM),format=(string)NV12" ! nv3dsink -e

Spinning. Please run 'gdb gst-launch-1.0 3676' to continue debugging, Ctrl-C to quit, or Ctrl-\ to dump core.
I really prefer nvv4l2camerasrc because it use DMA BUFFER.
Please help me. Thanks in advance.
