yes, its dependant on motion estimation. the frame_drop_ratio simply checks 
the number of skipped-macroblocks. when given two identical frames, xvid 
"should" drop the second frame.

if you want a frame dropping solution that operates independant of m.e., 
then we have to perform a simularity check between the current and reference 
frames within xvid. what algorithm does your filter use to identifiy simular 
frames?

note: xvid has already has an image-based mad function 
(xvidcore/src/image/image.c::image_mad). this is currently used to detect 
keyframes when bframes are enabled.
