Scalar module: Runtime change output image size

Dear Sirs,

I use DM8148 and HDVPSS_01_00_01_33. My link path is Capture -> Scalar -> Display.

Is it possible that runtime change scalar output image size?

For example:

Input image size: 1280x800 and output image size: 720x480.

then I want to change output image size: 600x400 by some IO_CTL.

I try to use IOCTL_VPS_WRITE_ADV_SC_CFG, but it doesn't work.

If you have confirmed answer, please reply to me. Thank you.
