#516 closed defect (fixed)

Setting weighted_bipred_idc=0 disables weighted prediction in P-slices.

Description

The function xPredInterBi( ) is called for both P- and B-slices. In this function, only the value of weighted_bipred_idc is used.

So, when coding a P-slice, the value of weighted_pred_flag if ignored, and setting weighted_bipred_idc=0 will incorrectly disable weighted prediction.

I believe the attached patch could be used to fix the issue.
