RPR - Combination with BDOF

Description

The bioApplied determination in the following function:

void InterPrediction::motionCompensation( PredictionUnit &pu, PelUnitBuf &predBuf, ... )

is missing a check for isRefPicSameSize for the RPR case.

Without this check, RPR still disables BDOF at a later point. However, not until after calling xSubPuBio, which results in each 16x16 sub-block being handled separately.

Calling RPR interpolation for individual 16x16 sub-blocks gives a different result than calling it once for the whole PU (because of accumulation of errors in xStep and yStep).
