Field Documentation

void(* AVFixedDSPContext::vector_fmul_window_scaled)(int16_t *dst, const int32_t *src0, const int32_t *src1, const int32_t *win, int len, uint8_t bits)

Overlap/add with window function.

Used primarily by MDCT-based audio codecs. Source and destination vectors must overlap exactly or not at all.

Parameters

dst	result vector constraints: 16-byte aligned
src0	first source vector constraints: 16-byte aligned
src1	second source vector constraints: 16-byte aligned
win	half-window vector constraints: 16-byte aligned
len	length of vector constraints: multiple of 4
bits	scaling parameter

void(* AVFixedDSPContext::vector_fmul_window)(int32_t *dst, const int32_t *src0, const int32_t *src1, const int32_t *win, int len)

Overlap/add with window function.

Used primarily by MDCT-based audio codecs. Source and destination vectors must overlap exactly or not at all.

Parameters

dst	result vector constraints: 32-byte aligned
src0	first source vector constraints: 16-byte aligned
src1	second source vector constraints: 16-byte aligned
win	half-window vector constraints: 16-byte aligned
len	length of vector constraints: multiple of 4
