From 6c5ff7c8e8800c95be96c59f02ea31b8860ad745 Mon Sep 17 00:00:00 2001 From: Sakari Ailus Date: Mon, 5 Sep 2016 12:15:15 -0300 Subject: [PATCH] [media] smiapp: Provide a common function to obtain native pixel array size The same pixel array size is required for the active format of each sub-device sink pad and try format of each sink pad of each opened file handle as well as for the native size rectangle.
