-==== Video Node ==== +
- +
-You can find the video node from the table below. +
- +
-|        ^  Video Node    ^ +
-^  CAM1  |  /dev/video33  | +
-^  CAM2  |  /dev/video24  | +
-^  CAM3  |  /dev/video42  | +

-==== Record Video with Gstreamer ==== +
- +
-=== Record Video === +
- +
-Record video from ''CAM1'': +
- +
-```shell +
-gst-launch-1.0 v4l2src device=/dev/video33 io-mode=mmap num-buffers=300 ! mpph264enc ! h264parse ! qtmux ! filesink location=/tmp/video33.mp4 +
-``` +
- +
-Record video from ''CAM2'': +
- +
-```shell +
-gst-launch-1.0 v4l2src device=/dev/video24 io-mode=mmap num-buffers=300 ! mpph264enc ! h264parse ! qtmux ! filesink location=/tmp/video24.mp4 +
-``` +
- +
-Record video from ''CAM3'': +
- +
-```shell +
-gst-launch-1.0 v4l2src device=/dev/video42 io-mode=mmap num-buffers=300 ! mpph264enc ! h264parse ! qtmux ! filesink location=/tmp/video42.mp4 +
-``` +
- +
-==== Record Video with OpenCV ==== +
- +
-=== Install OpenCV === +

-``` +
- +
-Test: +
- +
-Capture frame from ''CAM1'': +
- +
-```shell +
-./mipi /dev/video33 +
-``` +
- +
-Capture frame from ''CAM2'': +
- +
-```shell +
-./mipi /dev/video24 +
-``` +
- +
-Capture frame from ''CAM3'': +
- +
-```shell +
-./mipi /dev/video42 +
-``` +
- +
-==== Capture Frame with V4L2 API ==== +
- +
-=== Install V4l2 Utils === +
- +
-```shell +
-sudo apt update +
-sudo apt install v4l-utils +
-``` +
- +
-=== Capture Frame === +
- +
-Capture frame from ''CAM1'': +
- +
-```shell +
-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'': +
- +
-```shell +
-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'': +
- +
-```shell +
-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 ''3840x2160 NV12'' format frame to file ''/tmp/dataXX.yuv''. +
- +
- +
-Preview the file: +
- +
-```shell +
-$ ffplay -f rawvideo -pixel_format nv12 -video_size 3840x2160 /tmp/dataXX.yuv+
