From 62e5ef95cacb29b5ee3149792f12f9204dbd1655 Mon Sep 17 00:00:00 2001 From: Michael Niedermayer Date: Thu, 12 Apr 2012 21:03:19 +0200 Subject: [PATCH] av_image_alloc: Align the width to 8 when align >= 8. This allows simd optimized routines to work in steps of 8 pixels without going over the linesize. (this matters for yuv->rgb24 for example) Signed-off-by: Michael Niedermayer --- libavutil/imgutils.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/libavutil/imgutils.c b/libavutil/imgutils.c index 75642d1913..ef7d4138ae 100644 --- a/libavutil/imgutils.c +++ b/libavutil/imgutils.c @@ -188,7 +188,7 @@ int av_image_alloc(uint8_t *pointers[4], int linesizes[4], if ((ret = av_image_check_size(w, h, 0, NULL)) < 0) return ret; - if ((ret = av_image_fill_linesizes(linesizes, pix_fmt, w)) < 0) + if ((ret = av_image_fill_linesizes(linesizes, pix_fmt, align>7 ?
