From 0423a964698fa64f499c916d77dcbc5bcad61d69 Mon Sep 17 00:00:00 2001 From: Adrian Grange Date: Thu, 1 May 2014 14:31:50 -0700 Subject: [PATCH] Fix mode selection bug when ARNR filtering disabled When ARNR filtering is disabled, by setting arnr_max_frames=0, mode_skip_mask was being set to -1 for the ARF frame resulting in no mode being selected for the block. The intent is to restrict the reference frame to the previous ARF frame and the mode to one of ZEROMV, NEARMV or NEARESTMV.
