This document mainly introduces the usage of IMX415 MIPI Camera.
The reverse connection will damage the camera, please check the connection of the picture carefully before connecting.
Please follow the documentation to upgrade your system to latest version.
You can find the video nodes from the table below.
Video Node(5.10.66) | Video Node(5.10.160) | |
---|---|---|
CAM1 | /dev/video33 | /dev/video42 |
CAM2 | /dev/video24 | /dev/video33 |
CAM3 | /dev/video42 | /dev/video51 |

Follow the steps below to install v4l-utils
:
sudo apt update sudo apt install v4l-utils
Capture frame from CAM1
:
v4l2-ctl -d /dev/video33 --set-fmt-video=width=3840,height=2160,pixelformat=NV12 --stream-mmap=3 --stream-skip=3 --stream-to=/tmp/data33.yuv --stream-count=1 --stream-poll
Capture frame from CAM2
:
v4l2-ctl -d /dev/video24 --set-fmt-video=width=3840,height=2160,pixelformat=NV12 --stream-mmap=3 --stream-skip=3 --stream-to=/tmp/data24.yuv --stream-count=1 --stream-poll
Capture frame from CAM3
:
v4l2-ctl -d /dev/video42 --set-fmt-video=width=3840,height=2160,pixelformat=NV12 --stream-mmap=3 --stream-skip=3 --stream-to=/tmp/data42.yuv --stream-count=1 --stream-poll
Capture frame from CAM1
:
v4l2-ctl -d /dev/video42 --set-fmt-video=width=3840,height=2160,pixelformat=NV12 --stream-mmap=3 --stream-skip=3 --stream-to=/tmp/data42.yuv --stream-count=1 --stream-poll
Capture frame from CAM2
:
v4l2-ctl -d /dev/video33 --set-fmt-video=width=3840,height=2160,pixelformat=NV12 --stream-mmap=3 --stream-skip=3 --stream-to=/tmp/data33.yuv --stream-count=1 --stream-poll
Capture frame from CAM3
:
v4l2-ctl -d /dev/video51 --set-fmt-video=width=3840,height=2160,pixelformat=NV12 --stream-mmap=3 --stream-skip=3 --stream-to=/tmp/data51.yuv --stream-count=1 --stream-poll
It will capture a 3840×2160 NV12
format frame to file /tmp/dataXX.yuv
.
Preview the file:
$ ffplay -f rawvideo -pixel_format nv12 -video_size 3840x2160 /tmp/dataXX.yuv
