From e5be4c5a88df90477f36cc81993d10f41d6180ce Mon Sep 17 00:00:00 2001 From: Xu Guangxin Date: Fri, 16 Oct 2020 21:57:34 +0800 Subject: [PATCH] avcodec/hevcdec: constrained intra predict, do not check top left IS_INTRA if it's not available fix ticket: 8932 For poc 2, we have tile boundary at x = 640. When we predict cu(640,912),the top left pixel is not avaliable to the cu. So, we can not check it's intra or not. We need set top[-1] = top[0] directly. see 8.4.4.2.1 for details Signed-off-by: Xu Guangxin Signed-off-by: Linjie Fu --- libavcodec/hevcpred_template.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/libavcodec/hevcpred_template.c b/libavcodec/hevcpred_template.c index f1a1f4c1f0..ca75ec1128 100644 --- a/libavcodec/hevcpred_template.c +++ b/libavcodec/hevcpred_template.c @@ -214,7 +214,7 @@ do { \ while (j < size_max_x && !IS_INTRA(j, -1)) j++; if (j > 0) - if (x0 > 0) { + if (cand_up_left) { EXTEND_LEFT_CIP(top, j, j + 1); } else { EXTEND_LEFT_CIP(top, j, j);
