Hi
I’m trying to create Argus::CaptureSession with 6 cameras to capture synchronized frames.
Each camera are Leopard LI-IMX490-GMSL2, and connected to Leopard LI-XNX-BOX-GMSL2.

Jetpack version is 32.5.1 and Leopard’s driver is installed. And each camera works correctly.

v4l2-ctl --list-devices show following.

$ v4l2-ctl --list-devices
vi-output, imx490 30-001b (platform:15c10000.vi:0):
        /dev/video0

vi-output, imx490 30-001c (platform:15c10000.vi:1):
        /dev/video1

vi-output, imx490 31-001b (platform:15c10000.vi:2):
        /dev/video2

vi-output, imx490 31-001c (platform:15c10000.vi:3):
        /dev/video3

vi-output, imx490 32-001b (platform:15c10000.vi:4):
        /dev/video4

vi-output, imx490 32-001c (platform:15c10000.vi:5):
        /dev/video5

But, when I called ICameraProvider::createCaptureSession with 3 or more cameras, It returns null pointer and status=3(STATUS_UNAVAILABLE).

I could create only 2 cameras CaptureSession with following pairs. Any other combinations were failed.

  • video0 + video1
  • video2 + video3
  • video4 + video5

Is this behavior driver related issue or libArgus limitation?

Here is reproduction code.
multicam_session.cpp (1.2 KB)

To compile code, run following.

$ g++ -o multicam_session -I/usr/src/jetson_multimedia_api/argus/include \
  -L/usr/lib/aarch64-linux-gnu/tegra \
  -lnvargus_socketclient

Test example

$ multicam_session 0 1 # create CaptureSession with video0 and video1
createCaptureSession was succeeded
$ multicam_session 0 2 # create CaptureSession with video0 and video2
Failed to create CaptureSession: 3

It’s better to contact with Leopard Imaging to do the suppprt.
