From dd8a76ab080d6862ec8e182e805794ebb27be8b0 Mon Sep 17 00:00:00 2001 From: Clément Bœsch Date: Wed, 5 Dec 2012 04:58:03 +0100 Subject: lavfi/gradfun: do not increment DC pointer for odd values. First DC is only used once otherwise. This also makes the code consistent with ASM versions. --- libavfilter/vf_gradfun.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'libavfilter/vf_gradfun.c') diff --git a/libavfilter/vf_gradfun.c b/libavfilter/vf_gradfun.c index a9eeca54f2..9255f614a2 100644 --- a/libavfilter/vf_gradfun.c +++ b/libavfilter/vf_gradfun.c @@ -56,7 +56,7 @@ DECLARE_ALIGNED(16, static const uint16_t, dither)[8][8] = { void ff_gradfun_filter_line_c(uint8_t *dst, const uint8_t *src, const uint16_t *dc, int width, int thresh, const uint16_t *dithers) { int x; - for (x = 0; x < width; x++, dc += x & 1) { + for (x = 0; x < width; dc += x & 1, x++) { int pix = src[x] << 7; int delta = dc[0] - pix; int m = abs(delta) * thresh >> 16; -- cgit v1.2.3
