V4L2 programming with ISI downscaling feature

[aso]

I am programming V4L2 on the evaluation board 8MNANOD4-EVK using Linux 4.14.78.

The custom camera board is connected to MIPI-CSI.
The output format of the camera is 1280x720, YUV.

I would like to use V4L2 programming to get the video data with the camera output data scaled to 800x480 by ISI downscaling feature.

Is this possible with V4L2 programming?
Or is it something you scale yourself with ISI?

Please let me know.

Thank you.

Hi aso

one can try with latest linux, run unit test capplication:

/unit_tests/V4L2/mx8_v4l2_cap_drm.out -cam 1 -ow 720 -oh 480 -of

Linux 4.14.78 does not support 8MNANOD4-EVK as described on below link, column "Supported Platforms"
