[FFmpeg-devel] [PATCH] avcodec/vvcdec: fix boundary strength when IBC involved

The following cases should set bs to 1: If the prediction modes are not the same. If both prediction modes are MODE_IBC, but the motion vector delta is larger than 8 of 1/16 pixels. see 8.8.3.5 How to reproduce it: vvencapp -i sintel_trailer_2k_1080p24.y4m --preset fast --additional "IBC=1" -o
