* swscale: add GBRAP14 format supportPaul B Mahol2023-09-28

* libswscale: force a minimum size of the slide for bayer sourcesChema Gonzalez2022-10-14
| | | | | | | | | Bayer sources are read in groups of 2 lines (e.g. for a BGGR flavor, the first row contains only B and G samples, while the second row contains only G and R samples). They need to be read as a whole. Signed-off-by: Anton Khirnov <anton@khirnov.net>
* all: Replace if (ARCH_FOO) checks by #if ARCH_FOOAndreas Rheinhardt2022-06-15
| | | | | | | | | | | | | | | | | | This is more spec-compliant because it does not rely on dead-code elimination by the compiler. Especially MSVC has problems with this, as can be seen in https://ffmpeg.org/pipermail/ffmpeg-devel/2022-May/296373.html or https://ffmpeg.org/pipermail/ffmpeg-devel/2022-May/297022.html This commit does not eliminate every instance where we rely on dead code elimination: It only tackles branching to the initialization of arch-specific dsp code, not e.g. all uses of CONFIG_ and HAVE_ checks. But maybe it is already enough to compile FFmpeg with MSVC with whole-programm-optimizations enabled (if one does not disable too many components).

* avutil/internal, swresample/audioconvert: Remove cpu.h inclusionsAndreas Rheinhardt2021-07-22
| | | | | | | | | | These inclusions are not necessary, as cpu.h is already included wherever it is needed (via direct inclusion or via the arch-specific headers). Also remove other unnecessary cpu.h inclusions from ordinary non-headers. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* swscale: Add support for NV24 and NV42Philip Langdale2019-05-12
| | | | | | | | | | | The implementation is pretty straight-forward. Most of the existing NV12 codepaths work regardless of subsampling and are re-used as is. Where necessary I wrote the slightly different NV24 versions. Finally, the one thing that confused me for a long time was the asm specific x86 path that did an explicit exclusion check for NV12. I replaced that with a semi-planar check and also updated the equivalent PPC code, which Lauri kindly checked.

* swscale: Add p016 output support and generalise yuv420p1x to p010Philip Langdale2018-03-02
| | | | | | | | To make the best use of existing code, I generalised the wrapper that currently does yuv420p10 to p010 to support any mixture of input and output sizes between 10 and 16 bits. This had the side effect of yielding a working code path for all yuv420p1x formats to p01x.
* swscale: use dithering in DITHER_COPY only if not set -sws_dither noneMateusz2017-10-25
| | | | | | | | | | | | This patch uses dithering in DITHER_COPY macro only if it was not used option '-sws_dither none'. With option '-sws_dither none' it uses downshift. For human eye dithering is OK, for video codecs not necessarily. If user don't want to use dithering, we should respect that.
