idct input permutation.

several optimized IDCTs need a permutated input (relative to the normal order of the reference IDCT) this permutation must be performed before the idct_put/add, note, normally this can be merged with the zigzag/alternate scan
an example to avoid confusion:

  • (->decode coeffs -> zigzag reorder -> dequant -> reference idct ->...)
  • (x -> reference dct -> reference idct -> x)
  • (x -> reference dct -> simple_mmx_perm = idct_permutation -> simple_idct_mmx -> x)
  • (->decode coeffs -> zigzag reorder -> simple_mmx_perm -> dequant -> simple_idct_mmx ->...)

void(* DSPContext::vector_clip_int32)(int32_t *dst, const int32_t *src, int32_t min, int32_t max, unsigned int len)

Clip each element in an array of int32_t to a given minimum and maximum value.

Parameters:
dst destination array constraints: 16-byte aligned
src source array constraints: 16-byte aligned
min minimum value constraints: must in the the range [-(1<<24), 1<<24]
max maximum value constraints: must in the the range [-(1<<24), 1<<24]
len number of elements in the array constraints: multiple of 32 greater than zero
