How capture single 8Mp image from rpi camera?

I am using the Arducam 8MP (Raspberry Pi) Camera Module V2, IMX219 Auto Focus Lens , I have both the mipi and the USB version, I can get the video with

gst-launch-1.0 -v v4l2src device=/dev/video2 ! ‘image/jpeg, width=3264, height=2448, framerate=15/1, format=MJPG’ ! jpegdec ! xvimagesink

but this is only video, and I can’t get the full resolution of 8Mp from the sensor with a single picture (like we can on rpi with raspistill), any idea on how to do it on Jetson ?

thanks,

v4l2-ctl --list-formats-ext --device /dev/video0

hello iliesaya,

please refer to L4T Accelerated GStreamer User Guide,
you might modify the gstreamer pipeline to include image encoder and dump it as jpg file.
for example,

$ gst-launch-1.0 nvarguscamerasrc num-buffers=1 ! 'video/x-raw(memory:NVMM), width=2592, height=1944' ! nvjpegenc ! filesink location=sample.jpg

please note that, you should enable different plugins for MIPI and USB sensors.
please check Camera Architecture Stack, that you should only enable v4l2src to access USB cameras.
thanks
