Motion Compensation Deinterlacer Ported from MPlayer libmpcodecs/vf_mcdeint.c.
Known Issues:
The motion estimation is somewhat at the mercy of the input, if the input frames are created purely based on spatial interpolation then for example a thin black line or another random and not interpolateable pattern will cause problems. Note: completely ignoring the "unavailable" lines during motion estimation did not look any better, so the most obvious solution would be to improve tfields or penalize problematic motion vectors.
If non iterative ME is used then snow currently ignores the OBMC window and as a result sometimes creates artifacts.
Only past frames are used, we should ideally use future frames too, something like filtering the whole movie in forward and then backward direction seems like a interesting idea but the current filter framework is FAR from supporting such things.
Combining the motion compensated image with the input image also is not as trivial as it seems, simple blindly taking even lines from one and odd ones from the other does not work at all as ME/MC sometimes has nothing in the previous frames which matches the current. The current algorithm has been found by trial and error and almost certainly can be improved...
