From 34d497283c66b5ef0f8855c007eaa20d7ac8b96d Mon Sep 17 00:00:00 2001
From: Marco Nelissen <marcone@google.com>

Subject: Expand AMediaFormat

Remove getDouble and getSize methods, since these are not used and/or
not present in the corresponding Java MediaFormat API.
Add setBuffer/getBuffer, needed for making formats for encoding, and
add other setters.
