Author: reimar
Date: Sat Feb 15 17:52:59 2014
New Revision: 36840

Log:
Switch to refcounted API since the old ones have memleaks.

A fixable one due to the "non-refcounting" API in fact still
using reference counting for the qp tables, and a probably
unfixable one (unless we add hacks MPlayer side) due to the
sidedata being copied.
