Looking the H265 reference at
https://www.itu.int/rec/dologin_pub.asp?lang=e&id=T-REC-H.265-201802-S!!PDF-E&type=items
go to function st_ref_pic_set( stRpsIdx ) at 7.3.7
inside that function there is a for loop with j variable.
for (j=0; j<=NumDeltaPocs[ refRpsIdc], j++){
}
where NumDeltaPocs is derived as:
NumDeltaPocs[ stRpsIdx ] = NumNegativePics[ stRpsIdx ]
+ NumPositivePics[ stRpsIdx ]
as you can see, it seems that num_negative_pics and num_positive_pics are unknown values. They are parsed in the else branch in pseudocode at 7.3.7
How can I implement that pseudocode?
