the motion estimation should already produce a "matching score" of some
kind for every block, its sum is probably a good indication how
similar frames are
the sum probably would need to be compared to some meassure of variance
for the frame so near black frames dont get better matches
a bit like a correlation coefficient
you can also look at
git grep scene libavcodec/mpegvideo* libavcodec/motion_es*
