From 8addae2583d68aaa4e904d7607b1d94ddc371860 Mon Sep 17 00:00:00 2001 From: Paul Elder Date: Sat, 4 Jul 2020 17:49:33 +0900 Subject: libcamera: StreamConfiguration: Add frameSize field In addition to the stride field, we want the pipeline handler to be able to declare the frame size for the configuration. Add a frameSize field to StreamConfiguration for this purpose.
