Anton Khirnov	e15371061d	lavu/mem: move the DECLARE_ALIGNED macro family to mem_internal on next+1 bump They are not properly namespaced and not intended for public use.	4 years ago
Anton Khirnov	c8c2dfbc37	lavu: move LOCAL_ALIGNED from internal.h to mem_internal.h That is a more appropriate place for it.	4 years ago
Andreas Rheinhardt	ead3134150	avcodec/mpegaudiodsp: Make ff_mpadsp_init() thread-safe The only thing missing for this is to make ff_mpadsp_init_x86() thread-safe; it currently isn't because a static table is initialized every time ff_mpadsp_init() is called (when ARCH_X86 is true). Solve this by initializing this table only once, namely together with the ordinary not-arch specific tables. This also allows to reuse their AVOnce.

James Almer	1a35fffaf2	x86/cfhddsp: zero extend int arguments if taken from stack, they may have garbage in the upper bits otherwise. Also, there are only 8 arguments, so don't attempt to load 11.

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.

Peter Ross	fd17218558	vp4: prevent unaligned memory access in loop filter VP4 applies a loop filter during motion compensation, causing the block offset will often by unaligned. This produces a bus error on some platforms, namely ARMv7 NEON. This patch adds a unaligned version of the loop filter function pointer to VP3DSPContext.

Mikulas Patocka	fbdd78fa3e	avcodec/fft: fix INTERL macro on 3dnow The commit `b7c16a3f2c` ("x86: fft: Port to cpuflags") breaks the opus decoder in ffmpeg when compiling for 3dnow. The output is audible, but there's a lot of noise. The reason for the breakage is that the commit unintentionally changed the INTERL macro so that it is empty when compiling for 3dnow.
