Date: Tue,  8 Feb 2022 06:02:37 -0500
Message-ID: <20220208110240.4179-1-qyot27@gmail.com> (raw)

AviSynth+ 3.6.0 introduced support for frame properties, allowing
various metadata to be passed between filters or read out by
client programs.  Using this, FFmpeg can read Color Range, Transfer
Characteristics, Matrix, Color Primaries, Chroma Location, and
Field Order information from AviSynth scripts.

Reading frame properties through AviSynth's C interface was not
possible until a few months ago, though, so client programs that
use the C API need version 3.7.1 or higher to be able to take
advantage of it.

Incorporates a previous patch by emcodem that fixes setting field
order on non-frameprop-aware versions of AviSynth.

  avisynth: use AviSynth+'s frame properties to set various fields
  configure: check avisynth header version

  avisynth: corrected interlace detection
