From 038e2fd66cd07354e2527e7e9aecd8a849f08799 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Niklas=20S=C3=B6derlund?= Date: Fri, 25 Sep 2020 00:18:43 +0200 Subject: libcamera: pipeline: rkisp1: Move start and stop of path to RkISP1Path MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Move the start and stop of a path to RkISP1Path. This allows the importing of buffers to be moved closer the path start/stop simplifying the code. Also by adding a simple running tracker the error logic in PipelineHandlerRkISP1 can be simplified as stop() can always be called. This also removes all external users of RkISP1Path::video_ so it can be made private.
