Edge-2L all camera interfaces support 4K@60fps record.

You can find the video nodes from the table below.

Record video from CAM0:

gst-launch-1.0 v4l2src device=/dev/video33 io-mode=dmabuf min-buffers=64 num-buffers=300 ! video/x-raw,format=NV12,width=3840,height=2160,framerate=30/1 ! mpph264enc ! h264parse ! qtmux ! filesink location=/tmp/video33.mp4

Record video from CAM1:

gst-launch-1.0 v4l2src device=/dev/video21 io-mode=dmabuf min-buffers=64 num-buffers=300 ! video/x-raw,format=NV12,width=3840,height=2160,framerate=30/1 ! mpph264enc ! h264parse ! qtmux ! filesink location=/tmp/video21.mp4

Capture frame from CAM0:

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 CAM1:

v4l2-ctl -d /dev/video21 --set-fmt-video=width=3840,height=2160,pixelformat=NV12 --stream-mmap=3 --stream-skip=3 --stream-to=/tmp/data21.yuv --stream-count=1 --stream-poll
