From 3f9eb321481de3e118632a594bf1b0c9001c281c Mon Sep 17 00:00:00 2001 From: Steve Kondik Date: Fri, 22 Apr 2016 18:32:39 -0700 Subject: audiopolicy: Add AudioSessionInfo API * This patch introduces a new API which allows applications to query the state of the audio effects system, and receive callbacks with the necessary information to attach effects to any stream. * In the future, this may come as part of the AudioPort system, but since that's an active area of development by Google, we will dodge it for now. * The policy now simply keeps a refcounted list of objects which hold various bits of stream metadata. Callbacks are sent on stream open/close to applications which might be listening for them.
