From 187a537904ef2193a4b5e0312349f95223ff8610 Mon Sep 17 00:00:00 2001 From: Alex Converse Date: Sat, 9 Apr 2011 17:22:04 -0700 Subject: Convert some undefined 1<<31 shifts into 1U<<31. MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit According to ISO 9899:1999 S 6.5.7/4: The result of E1 << E2 is E1 left-shifted E2 bit positions; vacated bits are filled with zeros. If E1 has an unsigned type, the value of the result is E1× 2^E2, reduced modulo one more than the maximum value representable in the result type. If E1 has a signed type and nonnegative value, and E1× 2^E2 is representable in the result type, then that is the resulting value; otherwise, the behavior is undefined. --- libavcodec/fraps.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'libavcodec/fraps.c') diff --git a/libavcodec/fraps.c b/libavcodec/fraps.c index 346f03439d..a142484a51 100644 --- a/libavcodec/fraps.c +++ b/libavcodec/fraps.c @@ -180,7 +180,7 @@ static int decode_frame(AVCodecContext *avctx, return -1; } /* bit 31 means same as previous pic */ - f->pict_type = (header & (1<<31))?
