From 8404d02d75586d4fc570096f72a46f5af13b80ed Mon Sep 17 00:00:00 2001 From: Naushir Patuck Date: Fri, 18 Sep 2020 10:42:23 +0100 Subject: libcamera: pipeline: ipa: raspberrypi: Rework drop frame signalling MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The IPA now signals up front how many frames it wants the pipeline handler to drop. This makes it easier to handle up-coming changes to the buffer handling for import/export buffers.
