From fec64fb75ac1e64e4bf6af7885170a51c637cd45 Mon Sep 17 00:00:00 2001 From: Hirokazu Honda Date: Fri, 27 May 2022 18:34:36 +0900 Subject: android: camera_stream: Add sourceStream Add a sourceStream field to the CameraStream class, meant to contain a reference to the direct stream which produces actual image data for streams of type CameraStream::Mapped. The sourceStream of mapped streams will be used in later patches to make sure for each Mapped stream at least one libcamera::Stream is queued to the libcamera::Camera.
