1. Fix multi-bit TestCpuFlag(A | B) checks in AYUVToNV12, AYUVToNV21, RAWToRGBA, NV12ToRGB24Matrix, NV21ToRGB24Matrix, MergeRGBPlane, and MergeXR30Plane to compare == (A | B) so AVX-512 VBMI/BW kernels are not dispatched when AVX512VBMI or AVX512VL is absent. 2. Fix 2-byte SVE2 heap buffer overflow on odd widths in I422ToARGB1555Row_SVE_SC and I422ToARGB4444Row_SVE_SC using trn1/trn2 + st2b under .b predicates. 3. Fix ARGBPolynomialRow_SSE2 to use packssdw before packuswb, and add missing vzeroupper to SplitRGBRow_AVX2. 4. Fix CalcFrameSsim to return 0.0 instead of 0.0 / 0 (NaN) when width <= 8 || height <= 8 so I420Ssim stays finite on small frames. 5. Fix negative-height vertical inversion in ConvertFromI420, SplitARGBPlane (when dst_a is NULL), I422Rotate, I010Rotate, and I210Rotate. 6. Fix horizontal flip (negative x/dx) in ScaleFilterCols_NEON (signed sbfx #16, #16 offset extraction) and ScaleAddCols1_16_C (shift x >>= 16 before indexing src_ptr). 7. Fix ConvertToARGB odd crop_x chroma alignment in NV12/NV21, src_u offset in I420/YV12/J420/H420/U420, and FOURCC_U422 calling U422ToARGB instead of H422ToARGB. 8. Remove dead 14-instruction block in ScaleRowUp2_Bilinear_16_SSE2. 9. Fix UVScale_16 for src_width == 1 (P010ToP410/P210ToP410), enable and fix column order in TransposeWx4_32_SVE2, fix ByteToFloatRow NEON Any BPP (3 -> 4), fix AB64ToARGBRow_Any_*, ScaleColsUp2_SSE2, ScaleUVRowDown2Box_SME, and UYVYToARGBRow_SME macro guards, fix SVE2 loop tail branches (b.lt/b.ge), and remove duplicate HAS_* macros. 10. Fix ConvertFP16ToFP32Column_NEON loop condition and unsigned b.lo underflow on widths < 8 or not multiples of 8. 11. Fix UYVYToNV12 IS_ALIGNED(awidth, ...) checks and WASM SIMD IS_ALIGNED(width, 16) checks in I420ToRGB24Matrix / I422ToRGB24Matrix. 12. Wire SplitUVRow_SVE2, SplitUVRow_LSX, and SplitUVRow_LASX in NV24ToARGB. 13. Fix MJpegDecoder heap buffer overflows in LoadFrame (reallocate databuf_[i] when scanlines_size changes), DecodeToBuffers, and DecodeToCallback (clamp scanlines_to_copy to lines_left and align skip to max_v_samp_factor). 14. Replace width & (vl - 1) tail calculations with post-loop remainder across 18 SVE2 functions in row_sve.h for non-power-of-2 SVE VL, and remove duplicate label 2: in UYVYToARGBRow_SVE_SC. 15. Handle width & 15 tail pixels in DetileToYUY2_C and validate IS_POWEROFTWO(tile_height) in DetileSplitUVPlane and DetileToYUY2. 16. Avoid signed 32-bit overflow in DivideRow_16_C and C16TO8, fix ClampFloatToZero_SSE2 pointer increment (lea 0x4) and loop counter (sub $0x1), and initialize xmm3 in ARGBCopyYToAlphaRow_SSE2. 17. Check max leaf 7 subleaf and max extended CPUID leaf in GetCpuFlags before querying subleaf 7:1 and extended leaf 0x80000021. 18. Free plane_u on error in I422ToNV21, and fix 4x/2x scratch row over-allocation in ScaleARGBBilinearDown and ScaleUVBilinearDown. 19. Add ARGBSetRow_RVV and ARGBShuffleRow_RVV in row_rvv.cc. 20. Fix NEON mask (15 -> 7) in ScaleUVRowUp2_Linear_Any_NEON / _16_Any_NEON, use SIMD InterpolateRow + SplitUVRow in NV16ToI420, wire SSSE3/SSE2 in ARGBToI400Matrix / ARGBToYUY2Matrix / ARGBToUYVYMatrix and RGB24Mirror, and split HalfFloatRow multiply into (src * scale) * 2^-112 to avoid 50x Intel denormal stalls.
