Macro Definition Documentation

◆ RocdecHevcPicture_RPS_ST_CURR_BEFORE

#define RocdecHevcPicture_RPS_ST_CURR_BEFORE   0x00000010

RefPicSetStCurrBefore of HEVC spec variable Number of ReferenceFrames[] entries with this bit set equals NumPocStCurrBefore.

RocdecHevcPicture_ST_CURR_BEFORE, RocdecHevcPicture_RPS_ST_CURR_AFTER and RocdecHevcPicture_RPS_LT_CURR of any picture in ReferenceFrames[] should be exclusive. No more than one of them can be set for any picture. Sum of NumPocStCurrBefore, NumPocStCurrAfter and NumPocLtCurr equals NumPocTotalCurr, which should be equal to or smaller than 8. Application should provide valid values for both int16_t format and long format. The pictures in DPB with any of these three flags turned on are referred by the current picture.
