From 1f4ff53aea7c5090f31cd1323d95f7c407c9b2bb Mon Sep 17 00:00:00 2001 From: Christophe Gisquet Date: Sat, 3 Oct 2015 18:59:17 +0200 Subject: dnxhddec: Introduce DNXHD_VARIABLE Currently not used, but will be used to indicate that a CIDEntry field is not set, because it is variable, and that checks should be adapted.
