From 5a0f6b099f3e8fcb95a80e3ffe52b3bf369efe24 Mon Sep 17 00:00:00 2001 From: Philip Langdale Date: Thu, 16 Nov 2017 07:31:58 -0800 Subject: avcodec: Fix reference data type for nvdec vc1 hwaccel I took the reference lookup code from the vp9 hwaccel where the type is unsigned char, but for vc1, the type is signed int. This is particularly important because the value used when there's no reference is different (255 vs -1). It didn't seem to break anything, but for mpeg1/2/4, this mistake caused decode errors. --- libavcodec/nvdec_vc1.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'libavcodec/nvdec_vc1.c') diff --git a/libavcodec/nvdec_vc1.c b/libavcodec/nvdec_vc1.c index cf75ba5aca..588a5b9d07 100644 --- a/libavcodec/nvdec_vc1.c +++ b/libavcodec/nvdec_vc1.c @@ -25,13 +25,13 @@ #include "decode.h" #include "vc1.h" -static unsigned char get_ref_idx(AVFrame *frame) +static int get_ref_idx(AVFrame *frame) { FrameDecodeData *fdd; NVDECFrame *cf; if (!frame || !frame->private_ref) - return 255; + return -1; fdd = (FrameDecodeData*)frame->private_ref->data; cf = (NVDECFrame*)fdd->hwaccel_priv; -- cgit v1.2.3
