From ae342991dc6ac4a68893024686da30f93d12ed9e Mon Sep 17 00:00:00 2001 From: Jacopo Mondi Date: Fri, 16 Apr 2021 11:25:32 +0200 Subject: libcamera: uvc: Report sensor timestamp MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Report the sensor's timestamp in the Request metadata using the completed buffer timestamp. The UVC driver reports timestamps of SOE event through metadata, for which there is no support in the current pipeline implementation.
