* avcodec/asvenc,dvenc: Optimize unaligned checks away if possibleAndreas Rheinhardt2025-05-311-1/+6
| | | | | | | | | For certain arches (AARCH64, x86, generic) get_pixels and get_pixels_unaligned always coincide for 8 bit input. In these cases it is possible to avoid checks for unaligned input in asvenc, dvenc. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* avcodec/pixblockdsp: Improve 8 vs 16 bit checkAndreas Rheinhardt2025-05-311-6/+6
| | | | | | | | | | | | | | | | | | | | | | | | | Before this commit, the input in get_pixels and get_pixels_unaligned has been treated inconsistenly: - The generic code treated 9, 10, 12 and 14 bits as 16bit input (these bits correspond to what FFmpeg's dsputils supported), everything with <= 8 bits as 8 bit and everything else as 8 bit when used via AVDCT (which exposes these functions and purports to support up to 14 bits). - AARCH64, ARM, PPC and RISC-V, x86 ignore this AVDCT special case. - RISC-V also ignored the restriction to 9, 10, 12 and 14 for its 16bit check and treated everything > 8 bits as 16bit. - The mmi MIPS code treats everything as 8 bit when used via AVDCT (this is certainly broken); otherwise it checks for <= 8 bits. The msa MIPS code behaves like the generic code. This commit changes this to treat 9..16 bits as 16 bit input, everything else as 8 bit (the former because it makes sense, the latter to preserve the behaviour for external users*). *: The only internal user of AVDCT (the spp filter) always uses 8, 9 or 10 bits.

* configure: Remove av_restrictAndreas Rheinhardt2024-03-151-6/+4
| | | | | | | | | All versions of MSVC that support C11 (namely >= v19.27) also support the restrict keyword, therefore av_restrict is no longer necessary since 75697836b1db3e0f0a3b7061be6be28d00c675a0.

* pixblockdsp, avdct: Add get_pixels_unalignedMartin Storsjö2020-05-131-0/+3
| | | | | | | | | | | | | 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.
