From b37aa4de2deb79aeb2b8c52a1696d796cde7ce72 Mon Sep 17 00:00:00 2001 From: Stefano Sabatini Date: Sun, 29 Nov 2009 18:02:19 +0000 Subject: [PATCH] Use the correct chroma values for the data[] array used in draw_slice(). The chroma values to use are supposed to be those of the input format, not that of the output format, the latter case was causing crashes and chroma issues.
