h.264 IPP API / Sample quantization questions

Hi!

I have same questions about h.264 IPP API / Sample.

1)
ippiTransformQuantFwd4x4_H264_16s_C1
ippiTransformQuantInvAddPred4x4_H264_16s_C1IR

These functions allow to use not FLAT Scale Levels (allow to use pointer pScaleLevels)?

2) Decoder based on IPP 5.3 Sample support other Scale Levels?

Thx.

Hello,

there is comment from our expert on your the first question

Yes, you should provide scale matrices based on your scaling list generated by function

ippiGenScaleLevel4x4_H264_8u16s_D2

I'm waiting for the comment on your second question

Regards,
Vladimir
