Cannot launch stream from camera using GStreamer

[dovydas1928]

Hi, I’m using the VC-MIPI camera driver on Jetson Linux R36.4.4 and I need help getting nvarguscamerasrc working.

This pipeline fails after a few seconds:

gst-launch-1.0 -e \
  nvarguscamerasrc sensor-id=0 ! \
  'video/x-raw(memory:NVMM),width=2048,height=1536,format=NV12,framerate=30/1' ! \
  fakesink sync=false

Got this output:

Why I got these errors:

nvbuf_utils: dmabuf_fd -1 mapped entry NOT found
Error generated. gstnvarguscamerasrc.cpp, threadExecute:734 NvBufSurfaceFromFd Failed.
Error generated. gstnvarguscamerasrc.cpp, threadFunction:245 (propagating)

Sensor streaming starts (vc_sen_start_stream(): Start streaming), but Argus/GStreamer stops with EOS.
I checked dependencies using the loader (/lib/ld-linux-aarch64.so.1 --list ...) and there are no missing libs.

Does anyone know what could cause dmabuf_fd to be -1 with Argus on R36.4.4 (device-tree module config / ISP config / required packages / known patches)?

I added this driver to my project: https://github.com/VC-MIPI-modules/vc_mipi_nvidia
