From 9278ce98f7198e61116043fe69f885bfca54ec1c Mon Sep 17 00:00:00 2001 From: Niklas Haas Date: Sun, 26 Jun 2016 19:04:36 +0200 Subject: vo_opengl: implement ARIB STD-B68 (HLG) HDR TRC This HDR function is unique in that it's still display-referred, it just allows for values above the reference peak (super-highlights). The official standard doesn't actually document this very well, but the nominal peak turns out to be exactly 12.0 - so we normalize to this value internally in mpv. (This lets us preserve the property that the textures are encoded in the range [0,1], preventing clipping and making the best use of an integer texture's range) This was grouped together with SMPTE ST2084 when checking libavutil compatibility since they were added in the same release window, in a similar timeframe. --- DOCS/man/vf.rst | 1 + DOCS/man/vo.rst | 2 ++ 2 files changed, 3 insertions(+) (limited to 'DOCS/man') diff --git a/DOCS/man/vf.rst b/DOCS/man/vf.rst index b4e4438f78..7f60da9385 100644 --- a/DOCS/man/vf.rst +++ b/DOCS/man/vf.rst @@ -311,6 +311,7 @@ Available filters are: :gamma2.8: Pure power curve (gamma 2.8) :prophoto: ProPhoto RGB (ROMM) curve :st2084: SMPTE ST2084 (HDR) curve + :std-b67: ARIB STD-B67 (Hybrid Log-gamma) curve ```` Reference peak illumination for the video file.
