From 595264f1af12e25dce57d7c5b1d52ed86ac0d0c9 Mon Sep 17 00:00:00 2001 From: Mathias Agopian Date: Tue, 16 Jul 2013 22:56:09 -0700 Subject: [PATCH] BufferQueue improvements and APIs changes this is the first step of a series of improvements to BufferQueue. A few things happen in this change: - setSynchronousMode() goes away as well as the SynchronousModeAllowed flag - BufferQueue now defaults to (what used to be) synchronous mode - a new "controlled by app" flag is passed when creating consumers and producers those flags are used to put the BufferQueue in a mode where it will never block if both flags are set. This is achieved by: - returning an error from dequeueBuffer() if it would block - making sure a buffer is always available by replacing the previous buffer with the new one in queueBuffer() (note: this is similar to what asynchrnous mode used to be) Note: in this change EGL's swap-interval 0 is broken; this will be fixed in another change.
