Subject: [FFmpeg-devel] [PATCH v2 1/5] avfilter/vf_yadif: Fix edge size when MAX_ALIGN is < 4
Date: Wed, 20 Jul 2022 19:25:10 -0700
Message-ID: <20220721022514.1466331-1-cphlipot0@gmail.com> (raw)
If alignment is set to less than 4 filter_edges will produce incorrect
output and not filter the entire edge. To fix this, make sure that
the edge size is at least 3.
