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. > http://git.videolan.org/gitweb.cgi/ffmpeg.git/?a=commit;h=5a0f6b099f3e8fcb95a80e3ffe52b3bf369efe24 --- libavcodec/nvdec_vc1.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) 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; _______________________________________________ ffmpeg-cvslog mailing list ffmpeg-cvslog@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-cvslog
