Rémi Denis-Courmont	1edac8eb46	lavc/pixblockdsp: RISC-V I get_pixels Benchmarks on SiFive U74-MC (courtesy of Shanghai StarFive Tech): get_pixels_c: 180.0 get_pixels_rvi: 136.7	2 years 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).

Martin Storsjö	7168adedbc	libavcodec: aarch64: Add a NEON implementation of pixblockdsp Cortex A53 A72 A73 get_pixels_c: 140.7 87.7 72.5 get_pixels_neon: 46.0 20.0 19.5 get_pixels_unaligned_c: 140.7 87.7 73.0 get_pixels_unaligned_neon: 49.2 20.2 26.2 diff_pixels_c: 209.7 133.7 138.7 diff_pixels_neon: 54.2 31.7 23.5 diff_pixels_unaligned_c: 209.7 134.2 139.0 diff_pixels_unaligned_neon: 68.0 27.7 41.7 Signed-off-by: Martin Storsjö <martin@martin.st>	5 years ago
Martin Storsjö	353aecbb28	pixblockdsp, avdct: Add get_pixels_unaligned Use this in vf_spp.c, where the get_pixels operation is done on unaligned source addresses. Hook up the x86 (mmx and sse) versions of get_pixels to this function pointer, as those implementations seem to support unaligned use. This fixes fate-filter-spp on armv7.

Diego Biurrun	de452e5037	pixblockdsp: Change type of stride parameters to ptrdiff_t This avoids SIMD-optimized functions having to sign-extend their line size argument manually to be able to do pointer arithmetic. Also adjust parameter names to be "stride" everywhere.	8 years ago
