Details about IntRefQPDelta requested


Hi everyone! It's pretty short the info about IntRefQPDelta we found in the mfxExtCodingOption2 section on - saying: 

Specifies QP difference for inserted intra MBs. This is signed value in [-51, 51] range. This parameter is valid during initialization and runtime. 

So what exactly does it mean and what result I should expect setting (by example) IntRefQPDelta = 10 in relation to IntRefQPDelta = 20 or IntRefQPDelta = -10? Any help is appreciated. 

Best, Andreas
