Forum Post: how to pack rsz output of raw into 12bit?

I need to get isp processed RAW 12 bit data out of ipipe (case 2).

Therefore, I let data from ipipe go into rsz with the pass-through mode.

I got 16 bit RAW from rsz.

How can I get 16->12bit pack compression onto the 16bit RAW data? like ISIF does?

I cannot find any hints in the docs.

Thanks.
