Andreas Rheinhardt	790f793844	avutil/common: Don't auto-include mem.h There are lots of files that don't need it: The number of object files that actually need it went down from 2011 to 884 here. Keep it for external users in order to not cause breakages. Also improve the other headers a bit while just at it. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>	9 months ago
Niklas Haas	736284e7b9	swscale/yuv2rgb: fix sws_getCoefficients for colorspace=0 The documentation states that invalid entries default to SWS_CS_DEFAULT. A value of 0 is not a valid SWS_CS_*, yet the code incorrectly hard-codes it to BT.709 coefficients instead of SWS_CS_DEFAULT.	1 year ago

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
