From 1585c4d9fbbba3ba70ae625923b85cd02cb8a0fd Mon Sep 17 00:00:00 2001 From: Andy McFadden Date: Fri, 28 Jun 2013 13:52:40 -0700 Subject: Pay attention to buffer timestamps When acquiring a buffer, SurfaceFlinger now computes the expected presentation time and passes it to the BufferQueue acquireBuffer() method. If it's not yet time to display the buffer, acquireBuffer() returns PRESENT_LATER instead of a buffer. The current implementation of the expected-present-time computation uses approximations and guesswork.
