31.8.2 mips_h264_iqt_setup

Description

Computes the inverse quantization matrix used by the mips_iqt() function. The default inverse quantization coefficient array as specified by the H.264 video compression standard is provided as mips_h264_iq_coeffs and can be used in place of the q parameter.

Include

dsplib_video.h
