From e202e515b7278e4b418df3ceafae3fdd2bd31128 Mon Sep 17 00:00:00 2001 From: Hans Verkuil Date: Fri, 20 Mar 2015 13:23:06 -0300 Subject: [PATCH] [media] vivid-tpg.c: fix wrong Bt.2020 coefficients Mistyping 0.2627 as 0.2726 I can understand, but -0.4598 as -0.4629? No idea how I managed that. Anyway, these coefficients are now correct again.
