From 73d4efc596ad7d476dc303a88d251a903ed31136 Mon Sep 17 00:00:00 2001 From: Carl Eugen Hoyos Date: Fri, 1 Feb 2019 23:18:05 +0100 Subject: [PATCH] lavu/imgutils: Use FFABS() instead of abs() for ptrdiff_t. Fixes a warning with clang: libavutil/imgutils.c:314:16: warning: absolute value function 'abs' given an argument of type 'ptrdiff_t' (aka 'long') but has parameter of type 'int' which may cause truncation of value --- libavutil/imgutils.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/libavutil/imgutils.c b/libavutil/imgutils.c index afc73e2def..c733cb5cf5 100644 --- a/libavutil/imgutils.c +++ b/libavutil/imgutils.c @@ -311,8 +311,8 @@ static void image_copy_plane(uint8_t *dst, ptrdiff_t dst_linesize, { if (!dst || !src) return; - av_assert0(abs(src_linesize) >= bytewidth); - av_assert0(abs(dst_linesize) >= bytewidth); + av_assert0(FFABS(src_linesize) >= bytewidth); + av_assert0(FFABS(dst_linesize) >= bytewidth); for (;height > 0; height--) { memcpy(dst, src, bytewidth); dst += dst_linesize;
