From 9b672d4017bb34992045da2632c3599da791cbc6 Mon Sep 17 00:00:00 2001 From: Michael Niedermayer Date: Sat, 13 Apr 2013 15:00:22 +0200 Subject: vf_mp: mp buffers are not compatible with the reference count system We thus must copy each frame on the vf_mp output. This fixes artifacts with "ffplay -threads 1 dnxhdconv.mov -vf mp=eq2=1:1" Signed-off-by: Michael Niedermayer --- libavfilter/vf_mp.c | 12 +++++++----- 1 file changed, 7 insertions(+), 5 deletions(-) diff --git a/libavfilter/vf_mp.c b/libavfilter/vf_mp.c index 9a05997dec..53cdd93d56 100644 --- a/libavfilter/vf_mp.c +++ b/libavfilter/vf_mp.c @@ -568,16 +568,18 @@ int ff_vf_next_put_image(struct vf_instance *vf,mp_image_t *mpi, double pts){ memcpy(picref->linesize, mpi->stride, FFMIN(sizeof(picref->linesize), sizeof(mpi->stride))); for(i=0; i<4 && mpi->stride[i]; i++){ - picref->buf[i] = av_buffer_create(mpi->planes[i], mpi->stride[i], dummy_free, NULL, - (mpi->flags & MP_IMGFLAG_PRESERVE) ?
