Capture of 5 NTSC cameras

Autonomous Machines Jetson & Embedded Systems Jetson TX2

Hi.
I designed a carrier board and connected five NTSC cameras to CSI. Fixed the device tree, 5 NTSC cameras appear as /dev/video0 to 4, but only /dev/video2 can image capture.
When capturing five NTSC cameras, is it necessary to modify the driver on Jetson?
thanks.

hello at-yama,

Jetson had support multiple camera use-case, please refer to [L4T multimedia API]-> [Sample Applications]-> [13_multi_camera] for example.

also,

  1. could you share your commands to access your camera sensors
  2. please test all your sensor individually following below commands.
v4l2-ctl -d /dev/videoX --set-fmt-video=width=1920,height=1080,pixelformat=RG10 --set-ctrl bypass_mode=0 --stream-mmap --stream-count=100
