From c49beead1926400dadf92e00de906300b41e3d21 Mon Sep 17 00:00:00 2001 From: Stephen Hutchinson <qyot27@gmail.com> Date: Sun, 28 Aug 2022 14:08:55 -0400 Subject: [PATCH] avformat/avisynth: read _SARNum/_SARDen from frame properties Initialized to 1:1, but if the script sets these properties, it will be set to those instead (0:0 disables it, apparently).
