Doing a frame capture using V4L2 utils command:
v4l2-ctl --stream-mmap --stream-count=1 --stream-to=file.raw
creates an unsupported raw image.
But, capture using Gstreamer works fine.

Your IMX219 sensor is a Bayer sensor, so the v4l capture is in bayer RG10 format. This is expected. You would have to debayer the frame into a suitable format such as RGB or YUV for viewing it.

When using nvarguscamerasrc, the RG10 frames are redirected through a bypass to ISP that performs debayering (and more) and provides NV12 format. Note that when capturing with v4l2-ctl, you should add option :

--set-ctrl bypass_mode=0

so that it won’t interfere with argus-daemon.

Hello !
I tried running the command :
v4l2-ctl --stream-mmap --stream-count=1 --stream-to=file.raw --set-ctrl bypass_mode=0
Still I am facing the old issue, the raw is not viewable.
Is there anything which am missing ?

You’re just missing a viewer supporting Bayer RG10 format. Sorry I can’t provide any link for this.
I’d suggest to use argus to get a debayered format.

Thanks @Honey_Patouceul !
