From 67d5f1023e4299a5f2741e2523e559d892f1bb56 Mon Sep 17 00:00:00 2001

Subject: [PATCH] h264dec: use a large enough field for reference list
modification values
pic_num can be at most 17-bit, so uint8_t is not sufficient.
Found-By: Bradley Sepos <bradley@bradleysepos.com>
CC: libav-stable@libav.org
