From e78e6c37efc98189c4c3d89acd3265d7a7ba6d05 Mon Sep 17 00:00:00 2001 From: Kostya Shishkov Date: Tue, 7 Aug 2012 19:32:20 +0200 Subject: g723_1: clip argument for 15-bit version of normalize_bits() It expects maximum value to be 32767 but calculations in scale_vector() which uses this function can give it ABS(-32768) which leads to wrong result and thus clipping is needed. --- libavcodec/g723_1.c | 1 + 1 file changed, 1 insertion(+) (limited to 'libavcodec/g723_1.c') diff --git a/libavcodec/g723_1.c b/libavcodec/g723_1.c index aabb03d447..e917f5a50c 100644 --- a/libavcodec/g723_1.c +++ b/libavcodec/g723_1.c @@ -290,6 +290,7 @@ static int scale_vector(int16_t *vector, int length) for (i = 0; i < length; i++) max = FFMAX(max, FFABS(vector[i])); + max = FFMIN(max, 0x7FFF); bits = normalize_bits(max, 15); scale = (bits == 15) ? 0x7FFF : (1 << bits); -- cgit v1.2.3
