From 9068f36dccb15646480e8751385f086215287655 Mon Sep 17 00:00:00 2001 From: Kostya Shishkov Date: Mon, 22 Feb 2010 13:51:32 +0000 Subject: Macroblock and block Huffman code sets are to be used by both Indeo 4 and Indeo 5, so make them global and move their initialization to the common place as well. And fix static VLC initialization, as ff_ivi_create_huff_from_desc() used old way to do so.
