dav1d 0.9.2
Quote:
0.9.2 is a small update of dav1d on the 0.9.x branch, focusing on adding SIMD on numerous small cases:
x86: SSE4 optimizations of inverse transforms for 10bit for all sizes
x86: mc.resize optimizations with AVX2/SSSE3 for 10/12b
x86: SSSE3 optimizations for cdef_filter in 10/12b and mc_w_mask_422/444 in 8b
ARM NEON optimizations for FilmGrain Gen_grain functions
Optimizations for splat_mv in SSE2/AVX2 and NEON
x86: SGR improvements for SSSE3 CPUs
x86: AVX2 optimizations for cfl_ac
This mostly concludes SIMD for SSSE3 (32+64), AVX2 and NEON (32+64). The rest are scaled-related and z1/z2/z3 and should not bring significant improvements in speed for most cases.
