From 79cdb1f19d8033cf2e291b284fe1419098d5df81 Mon Sep 17 00:00:00 2001 From: Umang Jain Date: Tue, 26 Oct 2021 12:51:45 +0530 Subject: android: post_processor: Consolidate contextual information Save and provide the context for post-processor of a camera stream via Camera3RequestDescriptor::StreamBuffer. We extend the structure to include source and destination buffers for the post processor, along with CameraStream::Type::Internal buffer pointer (if any). In addition to that, a back pointer to Camera3RequestDescriptor is convenient to get access to overall descriptor (status, metadata settings etc.). Also, migrate CameraStream::process() and PostProcessor::process() signature to use Camera3RequestDescriptor::StreamBuffer only. This will be helpful when we move to async post-processing in subsequent commits.
