Module: libav Branch: master Commit: 3fd22538bc0e0de84b31335266b4b1577d3d609e
Author: Diego Biurrun <di...@biurrun.de> Committer: Diego Biurrun <di...@biurrun.de> Date: Wed Aug 24 11:52:10 2016 +0200 prores: Change type of stride parameters to ptrdiff_t This avoids SIMD-optimized functions having to sign-extend their line size argument manually to be able to do pointer arithmetic. Also adjust parameter names to be "linesize" everywhere. --- libavcodec/proresdsp.c | 6 +++--- libavcodec/proresdsp.h | 3 ++- libavcodec/proresenc.c | 19 ++++++++++--------- libavcodec/x86/proresdsp.asm | 3 +-- libavcodec/x86/proresdsp_init.c | 6 +++--- 5 files changed, 19 insertions(+), 18 deletions(-) diff --git a/libavcodec/proresdsp.c b/libavcodec/proresdsp.c index 3af2f0b..f782c90 100644 --- a/libavcodec/proresdsp.c +++ b/libavcodec/proresdsp.c @@ -36,11 +36,11 @@ /** * Add bias value, clamp and output pixels of a slice */ -static void put_pixels(uint16_t *dst, int stride, const int16_t *in) +static void put_pixels(uint16_t *dst, ptrdiff_t linesize, const int16_t *in) { int x, y, src_offset, dst_offset;
