From 94cbaa381aa8b1b3f34ad8bf14989456ba79a9af Mon Sep 17 00:00:00 2001 From: Laurent Pinchart Date: Wed, 1 Sep 2021 23:22:40 +0300 Subject: libcamera: formats: Add planeSize() helpers to PixelFormatInfo Add two helpers functions to the PixelFormatInfo class to compute the byte size of a given plane, taking the frame size, the stride, the alignment constraints and the vertical subsampling into account. Use the new functions through the code base to replace manual implementations.
