Niklas Haas	bf0a6c4111	avutil/csp: add av_csp_trc_inv_from_id() Mathematical inverse of av_csp_trc_from_id(), plus testing to make sure it roundtrips correctly with the corresponding TRC.	3 months ago
Niklas Haas	ec0489e35c	avutil/csp: fix documentation of av_csp_trc_function This explanation was inaccurate and highly misleading. The new wording is taken more or less directly from ITU-T H.273, and also matches my understanding of these functions.	3 months ago
Leo Izen	719a93f4e4	avutil/{color_utils, csp}: merge color_utils into csp and expose API libavutil/color_utils contains some avpriv_ symbols that map enum AVTransferCharacteristic values to gamma-curve approximations and to the actual transfer functions to invert them (i.e. -> linear). There's two issues with this: (1) avpriv is evil and should be avoided whenever possible (2) libavutil/csp.h exposes a public API for handling color that already handles primaries and matricies I don't see any reason this API has to be private, so this commit takes the functionality from avutil/color_utils and merges it into avutil/csp with an exposed av_ API rather than the previous avpriv_ API. Every reference to the previous API has been updated to point to the new one. color_utils.h has been deleted as well. This should not break any applications as it only contained avpriv_ symbols in the first place, so nothing in that header could be referenced by other applications.

Marvin Scholz	88e78ec6a8	avutil/csp: Fix bogus doxy filename Separate the blocks to make the grouping easier to grasp, add the file properly to the group and fix the file description incorrectly used as filename, fixing the following doxy warning: warning: the name 'Colorspace' supplied as the argument in the \file statement is not an input file	2 years ago
Leo Izen	d42b410e05	avutil/csp: create public API for colorspace structs This commit moves some of the functionality from avfilter/colorspace into avutil/csp and exposes it as a public API so it can be used by libavcodec and/or libavformat. It also converts those structs from double values to AVRational to make regression testing easier and more consistent. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	3 years ago
