* avcodec/pixblockdsp: Improve 8 vs 16 bit checkAndreas Rheinhardt2025-05-311-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | 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.
