From 7ed827e0a09bffabf4b2c4bc2a506e9563207a93 Mon Sep 17 00:00:00 2001 From: Paul Elder Date: Sat, 4 Jul 2020 17:55:57 +0900 Subject: libcamera: raspberrypi: Fill stride and frameSize at config validation Fill the stride and frameSize fields of the StreamConfiguration at configuration validation time instead of at camera configuration time. This allows applications to get the stride when trying a configuration without modifying the active configuration of the camera.
