Vapoursynth HDR to SDR not working as expected
#3
Had a quick look and the issue seems that Hybrid sets the Transfer information to a wrong value.
MediaInfo report:
Color range                              : Limited
Color primaries                          : BT.2020
Transfer characteristics                 : PQ
Matrix coefficients                      : BT.2020 non-constant
Mastering display color primaries        : Display P3
Mastering display luminance              : min: 0.0500 cd/m2, max: 1200 cd/m2
about the "LG New York HDR UHD 4K Demo.ts" source
clip = clip if not core.text.FrameProps(clip,'_Transfer') else core.std.SetFrameProps(clip, _Transfer=9)
which is wrong PQ <> smpte2084 and thus should be 16 (https://github.com/vapoursynth/vapoursyn...nstants4.h).

-> I'll fix it after work.
