Comment (by _theman):
The Rec.2020 standard defines new RGB<-->YUV matrix coefficients,
RGB<-->R'G'B' transfer coefficients, and primaries. Support for these need
to be implemented in SWScale to enable conversion between the Rec.2020
standard and the previous Rec.601 and Rec.709 standards. Additionally,
Rec.2020 uses a 10-bit working precision (64-940 range) for the data
format.
The important operations that need to be supported are:
- 10-bit end-to-end operation for transcoding and filtering.
- Color conversion (CMS) from Rec.2020 to sRGB/Rec.709 gamut. This implies
support for:
- * Gamut and gamma conversion through color management (CMS).
- * New RGB/YUV matrices for RGB-->YUV conversion.
