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.
