From 2c0fad508cf64624b22cca74e623eb2a2f2c29ef Mon Sep 17 00:00:00 2001 From: Laurent Pinchart Date: Fri, 1 May 2020 03:22:46 +0300 Subject: libcamera: pipeline: raspberrypi: Start IPA when starting camera MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The IPA is meant to be started when starting the camera, and stopped when stopping it. It was so far started early in order to handle the IPAInterface::processEvent() call related to lens shading table allocation before IPAInterface::configure() to pass the table to the IPA. Now that the lens shading table is passed through configure(), starting the IPA early isn't needed anymore.
