Zaggy1024	6b392cef9c	LibVideo: Treat BT.601/709/2020 input transfer characteristics as sRGB ... I've realized that it probably makes more sense to change the input transfer characteristics to treat these as sRGB since color conversion in linear converted from BT.709 doesn't really make sense. If content creation applications expect media players to display BT.709 without conversions, this means they expect applications to treat it as sRGB, since that's what most displays use. That most likely also means they process it as sRGB internally, meaning we should do the same for our color primaries conversion.	2022-11-11 11:34:03 +01:00
Zaggy1024	3720f66bb1	LibVideo: Set CodingIndependentCodePoints in its member functions ... This moves the setting of code points in CICP structs to member functions completely so that the code having to set these code points can be much cleaner.	2022-10-31 14:47:13 +01:00
Zaggy1024	cd127b65c3	LibVideo: Implement CICP color space conversion ... This adds a struct called CodingIndependentCodePoints and related enums that are used by video codecs to define its color space that frames must be converted from when displaying a video. Pre-multiplied matrices and lookup tables are stored to avoid most of the floating point division and exponentiation in the conversion.	2022-10-25 11:06:11 +02:00
