From 18691c538b9dad777bd61fe8400289298c78ac10 Mon Sep 17 00:00:00 2001 From: David Plowman Date: Mon, 8 Mar 2021 22:39:37 +0000 Subject: ipa: raspberrypi: Make CamHelpers return the frame delay for vblanking For some sensors (e.g. imx477) we need to update the vblanking on the frame before the exposure. For this reason the GetDelays method must also return the number of frame delays for the vblanking control.
