Niklas Haas	6da940e118	swscale/graph: allow dynamically updating HDR metadata Without triggering a full graph reinit.	2 months ago
Niklas Haas	efff80c8f6	swscale/graph: add color mapping pass This leverages the previously introduced color management subsystem in order to adapt between transfer functions and color spaces, as well as for HDR tone mapping. Take special care to handle grayscale formats without a colorspace gracefully.	2 months ago
Niklas Haas	45f0a7ad33	swscale: add ICC intent enum and option This setting can be used to infuence the type of tone and gamut mapping used internally when color space conversions are required. As discussed at VDD'24, the default was set to relative colorimetric clipping, which is approximately associative, surjective and idempotent. As such, it roundtrips well, although it is strictly speaking not associative on out-of-gamut colors.	2 months ago
Niklas Haas	79452d382f	swscale/graph: fix memleak of cascaded graphs Just free them directly and discard the parent context. Fixes: `bf738412e8` Signed-off-by: Niklas Haas <git@haasn.dev> Sponsored-by: Sovereign Tech Fund	3 months ago
Niklas Haas	bf738412e8	swscale/graph: add new high-level scaler dispatch mechanism This interface has been designed from the ground up to serve as a new framework for dispatching various scaling operations at a high level. This will eventually replace the old ad-hoc system of using cascaded contexts, as well as allowing us to plug in more dynamic scaling passes requiring intermediate steps, such as colorspace conversions, etc. The starter implementation merely piggybacks off the existing sws_init() and sws_scale(), functions, though it does bring the immediate improvement of splitting up cascaded functions and pre/post conversion functions into separate filter passes, which allows them to e.g. be executed in parallel even when the main scaler is required to be single threaded. Additionally, a dedicated (multi-threaded) noop memcpy pass substantially improves throughput of that fast path. Follow-up commits will eventually expand this to move all of the scaling decision logic into the graph init function, and also eliminate some of the current special cases.
