The mlib_VideoIDCT8x8_S16_S16_Q1_Mismatch() function computes the inverse IDCT in the inter mode.
This function is similar to mlib_VideoIDCT8x8_S16_S16_Q1() which should only be used when coeffs[u][v] (u,v = 0...7) are nonzero only for u and v less then 4. However, this function also allows element coeffs[7][7] to be nonzero. The primary benefit of this modification is that it can handle situations where coeffs[7][7] has been made nonzero by MPEG mismatchcontrol, allowing a simplified version of the IDCT to be undertaken for a much larger number of situations.
The function takes the following arguments:
block
coeffs
The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
