Andreas Rheinhardt	40e6575aa3	all: Replace if (ARCH_FOO) checks by #if ARCH_FOO 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).

Manuel Stoeckl	ca594df622	swscale/yuv2rgb: fix conversion to X2RGB10 This resolves a problem where conversions from YUV to X2RGB10LE would produce color values a factor 4 too small, because an 8-bit value was placed in a 10-bit channel.

Andreas Rheinhardt	2c05ee092b	avutil/internal, swresample/audioconvert: Remove cpu.h inclusions 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>	3 years ago

Ronald S. Bultje	b64a72e1b2	yuv2rgb: handle line widths that are not a multiple of 4. This introduces support for width%4==2 in addition to width%4==0.
