From 7d2714d1abb432575e667870e0248e2ee77ed9a4 Mon Sep 17 00:00:00 2001 From: Philip Langdale Date: Sun, 12 Jun 2011 20:21:28 -0700 Subject: [PATCH] CrystalHD: Keep mp4toannexb filter around for entire decoder lifetime. In preparation for using the filter on the actual bitstream, we need to extend it's lifetime to match that of the decoder.
