From c0417c4d524ca6c5421c3491bb95af1aabe0d067 Mon Sep 17 00:00:00 2001 From: Umang Jain Date: Tue, 17 Aug 2021 12:29:58 +0530 Subject: pipeline: ipu3: Skip recording timestamp for cancelled buffers There is no point in recording sensor's timestamp when V4L2VideoDevice has marked the frame buffers with FrameMetadata::FrameCancelled (happens when the streams are stopped). The metadata is mostly invalid for cancelled buffers hence, setting timestamp on invalid metadata does not make sense (however some metadata can be considered valid for e.g. returning cause of failure through metadata on cancelled buffers).
