Here I attach a preliminary version of a patch for precompute_partition_info_sums_() function that should accelerate encoding of 24-bit input data.
1) SSE2, SSSE3 and AVX2 versions of this function should be updated, too
2) the patch also changes
if(FLAC__bitmath_ilog2(default_partition_samples) + bps +
FLAC__MAX_EXTRA_RESIDUAL_BPS < 32)
into (in effect)
if(FLAC__bitmath_ilog2(default_partition_samples) + bps +
FLAC__MAX_EXTRA_RESIDUAL_BPS <= 32)
So, should the value of FLAC__MAX_EXTRA_RESIDUAL_BPS be increased (to 5? or to
6?)
3) any comments?
precomp_partitions.patch
