[Mp4-tech] About calculation of SAD in JM10.2

[A R]

Hi dear researchers !
I am working on H.264's reference model JM10.2 . In this reference code I want to change the SAD with my own method. As a big picture I know that, in SAD, two image values(as parameters) are required in calculating SAD between them. The problems I am facing right now are:
1- I could not find/identify these two parameters in this reference code.
2- I could not find/Identify the methods or functions in the code which are dedicated to calculate the SAD.Note: I found three functions/Methods namely SATD() , SATD8X8() and find_SAT() but they do not answer any of the questions above.
I'll really be grateful if someone can help in this regard. Thanks.
Kind Regards,
Amir Raza. (LUMS, Lahore, Pakistan)
