[libcamera-devel] [PATCH v2 04/12] android: camera_stream: Plumb process() with Camera3RequestDescriptor

Data (or broader context) required for post processing of a camera request
is saved via Camera3RequestDescriptor. Instead of passing individual
arguments to CameraStream::process(), pass the Camera3RequestDescriptor
pointer to it. All the arguments necessary to run the post-processor can
be accessed from the descriptor.
