This document mainly introduces the usage of IMX415 MIPI Camera.

Please follow the documentation to upgrade your system to latest version.

You can find the video node from the table below.

Compile:

gcc -o mipi mipi-camera.cpp -lopencv_imgproc -lopencv_core -lopencv_videoio -lopencv_imgcodecs -lopencv_highgui -std=c++11 -std=gnu++11 -Wall -std=c++11 -lstdc++ -I/usr/include/opencv4

Test:

./mipi /dev/video33

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

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
