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.

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. |
