From 3173c2190910a748d1a97b19a94ef4c47e48cb14 Mon Sep 17 00:00:00 2001 From: Adrian Grange Date: Mon, 25 Nov 2013 08:49:58 -0800 Subject: Change default behavior to assume sampled chroma When calling check_initial_width through vp9_set_size_literal the function was defaulting to using non-subsampled chroma. This patch changes the default to assume sampled chroma as an interim solution until complete support for other color formats is added.
